Bitcoin Miner Vergleich 2020: Test der Anbieter & Hardware
I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build).

At which time I'd be obliged to send an itemized list or see if I have what they're/you're specifically looking for.\* ______________________ THERMAL APPLICATIONS/FANS - JUST FANS - BeQuiet - Pure Wings 2 (80mm) Pure Wings 2 (120mm) Pure Wings 2 (140mm) Silent Wings 3 PWM (120mm) NOCTUA - PoopBrown - NF-A20 PWM (200mm) Specifically for the BIG "CoolerMaster HAF XB EVO" Case GREY - NF-P12 Redux - 1700RPM (120mm) PWM Corsair - Air Series AF120LED (120mm) CPU COOLING SYSTEMS - NOCTUA - NT-HH 1.4ml Thermal Compound NH-D15 6 Heatpipe system (this thing is the tits) EVGA (Extremely crappy coding in the software here, I'm like 99.99% these will be problematic if I were to try and use in any OS outside of Windows, because they barely ever work in the intended Windows as it is). CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)
part 3: down the NodeRed rabbit hole - resurrection (long)
so, now that i've got about 4 weeks of NR experience under my belt, i thought i would do a follow up and show a few new flows. plus, i've picked up a few new hardware add-ons. namely a Harmony Hub and a coupla Sonoff/Tasmota S31. one of the new things i did was setup some global.variables i can use in any flow. https://imgur.com/YFJEwRd 1] is pretty obvious, does my bayesian sensors think i'm home/not_home, and then save it to a global.variable. 2] reads the MQTT for my S31 power monitor on my dumb TV. if it's > 100, then the TV is ON, <= 99, then TV is OFF (or in the process of turning off). then set a global.variable for on/off. https://imgur.com/mcuS1Vk 3] i changed the day/night temperatures to global.variables. 4] this one gets the current volume level of my Sonos and then stores that to a global.variable. (get to why further below) 5] this one i talked about in another post here: https://www.reddit.com/homeassistant/comments/abvqup/device_tracker_with_unifi2mqtt/ okay, so now that i know if my dumb TV is on/off, then i can add it into my "away" (and "bedtime") flow. that gray one on the bottom right is using the HarmonyHub control node to fire the power toggle. (which i'll get to further below) plus it'll stop my Sonos, if it's playing. https://imgur.com/nerbMv3 also you may notice the "alexa TTS" one, that's a subflow, which is a bit of reusable flow, you can put anywhere you want it. this one picks a random number between 1 and 10, then alexa TTS plays the corresponding message. https://imgur.com/bLtBlaD this was also my attempt to get alexa to say "aaaf-firmative" like newt in aliens. https://imgur.com/cUnG1IE doesn't really work, but i'm determined to make this happen. gonna have to figure out the proper phonetics of it. then i'm totally gonna get her to do a stutter like max headroom on one of the other responses. but, my ultimate goal is to get her to do "twiki" from buck rogers. beaty beaty anyways, i've also added that subflow to all my switch on/offs. along with an MQTT log. https://imgur.com/SnpAnW8 now for some of the new stuff... here's a sleep timer. if i'm listening to music in bed, i can activate this with "alexa turn on sleep" and what it does, is it takes the current volume level of my Sonos, stored in a global.var, stores it in a flow.var, then subtracts 1 every minute, until it reaches zero. if the volume is at 30, then it'll be 30 mins until zero. https://imgur.com/7QmbY2S once it reaches zero, it stops the music, sets the volume back to the original state (ie: 30) and then turns itself off. there's an issue when you use something like a Harmony Hub to turn on/off dumb devices via input_bool, or switches, or lights, etc.: that once you turn it on via NR, HA, HHub, Alexa, etc., then HA thinks it's on. if you then turn it off via the device remote, HA won't let you turn it on again, because HA thinks its already on. so, i had to use a script and a "dummy" input_boolean. by dummy i mean, that i do not care, and will not EVER care, what it's state is. on. off. whatever. won't need it. it just needs to be there for the script to work.
input_boolean: mac_x: game_x: candles_x: tv_x:
hide them from emu_hue, cause Alexa doesn't need to see them either.
so instead of key'ing off the input_booleans, i key off the script call. "alexa, turn on candles" calls the script, which toggles the i_b but i only care about the state change of the script. then NR does it's thing. https://imgur.com/Hky9fWd notice tho, that it's a little smart. if the tv is already on, via that global.var, then it just switches inputs, otherwise it turns it on, waits 7 seconds, then switches inputs. okay, here's something REALLY advanced. i have a second pi running cgminer with a USB hub and some USB stick ASIC bitcoin miners. and every once and a while, they stop working and need to be reset. and you can't just restart, you gotta kill the power to the hubs to get them to reset. and then restart cgminer. enter NR cgminer node and the cgminer API. https://imgur.com/POSkjrp so every 5 mins, hit the cgminer API, it returns stats in json, dump those to mqtt. use the function node to pull out the array nested values we need to look at. look for a zero value in any of them. if the input_boolean "auto-reset-miner" is on, then lets reset. stop cgminer, wait, turn off the USB hub, wait, turn on hub, wait, start cgminer, send an alert to mqtt and SMS me. now the real magic is the red exec "start cgminer" node. because we stopped cgminer, we have to start it again, on a whole other computer than NR is on. it basically does a SSH into the miner pi and starts up cgminer. this was difficult to accomplish inside a docker of NR. i had to move some ssh keys around and then reference them with full paths. then i had to do an ssh-copy-id so it didn't require a password.
Full Node Hardware Configuration Requirements - Multi-GPU and Legendary USB Mining
Make mining great again! Unlike traditional Bitcoin and Ethereum nodes, Cortex has a higher hardware requirement for full node. This requires a relatively larger amount of hard disk storage and a multi-GPU desktop host for the best possible speed of confirmation, but this is not a must. In the field of Bitcoin mining, the USB miner used to be a popular plug and play small ASIC mining device. Before the large-scale mining farms emerged, this decentralized mining mode was extremely popular. Cortex full node in the absence of GPU can be configured to have the similar neurocomputers with special AI chips, and computing stick, which have matured in the market. Unlike Bitcoin USB Mining, the computing stick is the complementary hardware to verify the full node, not the equipment needed in the specific process of mining.

Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority. The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin. Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value. Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers. The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone. Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency. The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies. Bitcoin creator, Satoshi Nakamoto What is the Mining of bitcoin? Technical details : During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized. The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network. Material : In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU. Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time. For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency. A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people. The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins. The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7. Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs. There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology. Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable. Software : There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains. Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner. If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.
Hi i just had an idea of buying 2 usb miners, now i know mining bitcoin and other popular coins will net me probably .0001 a day or a week im fully aware of this fact but what i want to try is mining any new coins will i be able to mine a few coins of them?? Im looking into getting the ff: GekkoScience Asic Rev.2 Double chip 2-Pac Compac-2 USB Stick Bitcoin Miner 15gh/s+ (BM1384x2 for tha sha algo and FutureBit Moonlander 2 Litcoin USB Miner 3 M/H to 5 M/H Scrypt performance per mine. I plan to hold them in hope that after 2-3 years the value increases just wanted to have an opinion if i even have th chance to mine a few coins instead of .00001 a coin and i am strictly speaking of new alt coins or others that are not well know
Want to invest in bitcoin but willing to accept more risk for more return? Maybe investing would be right for you!
As we all know, companies such as AsicMiner are currently kicking butt with their asics by releasing the eruptor blades and Erupter USB sticks for mining. This combined with their 28% or so of total hashing power for the entire bitcoin network is resulting in fantastic growth over the past few months, and their dividends are doing quite well. If you are interested in shares of AsicMiner , check out either Direct Shares or Pass Through shares, which is just one share of AsicMiner. You can find them in auctions on bitcointalk as well as sites such as BTCT.TO
There are other shares too, such as AMC which just recieved a few Avalons they purchased a while ago. Keep in mind that the owners relations with others on the forum is quite poor and very unprofessional, so I would still consider it rather risky.
There are also companies which are not based on bitcoin but experimenting with it as a source of capital, such as KenilWorth on bitfunder, who are a mining company which finds raw material deposits and then sells them to another company (I think). The people with that company are VERY responsive on bitcointalk and seem to be very professional.
You can even if you wish bet on funds which are reliant upon BFL's shipping, such as HaveLock's Investments Mining Fund. The owner of that fund is also rather response on bitcointalk and is a very down to earth person from what I have seen. For example, they just purchased a single Jupiter rig from KnCMiner in an effort to diversify so if BFL fails they will not be destroyed.
They are also other funds out there which are designed to represent an amount of Mhash/s per each share, for example RedStarMining which aims to have 180 Ghash/s eventually, with each share containing 2.818 Mhash/s.
Also, a very cool thing about these funds is that they are very present on bitcointalk in the securities section, so you can see up to date discussion about each fund. For example, for red star mining, here is their thread: https://bitcointalk.org/index.php?topic=63257.0 You can even get a fund in an exchange, such as Crypto-Trade! Though, they seem to be having some major issues with their site for a while now, which is unfortuntate.
There are tons of such securities available for lots of different styles people could choose, and because of bitcoin buying these shares is a very painless process. But do keep in mind that this is riskier than just holding bitcoin, and there are a good bit of scams prevalent in such securities, but if you keep an eye out and read their associated threads on bitcointalk you will be for the most part safe. Also, investing in companies like AsicMiner increases the network hash rate, making it even harder for a single entity to barge in and get more than 50% of the network hash rate, resulting in an even more secure network! These sometimes even hare shares which cost less than five dollars, so to get started you don't need much BTC at all. And here is the link to bitcointalk for anyone who wants to do more research and look at any other funds which might be of interest. Don't forget that there are some funds which are not exchanged on these sites, for example group buys where each buyer holds a certain percentage of proceeds from a very expensive miner they pool together to buy. As earlier though, be careful.
There is also a really good subreddit for discussing these securities as well as others on /BitcoinStocks ! Edit: Added in bitcointalk threads for each security I listed. Edit: It seems that there are nearly half as many downvotes as there are upvotes. Can anyone clarify?
Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it. https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg 1) Hardware List -Raspberry Pi Model B --SD Card --Micro USB power supply --Ethernet cable -Gridseed ASIC --12V power supply (5.5mm/2.5mm barrel connector) --USB to Mini USB data cable The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware. The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that. The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too. 2) Software If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be). Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software. Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now
Log back in with the pi user once the Raspberry Pi is finished rebooting. The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in. To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0
So I decided to document my venture into cryptoland. It is not intended as a lecture, noob guide or even an attempt to get noticed by Readers Digest. Just have a few laughs at my expense and help me where I get it wrong. I'm not a writer by any stretch of the imagination. English is not even my first language. So here goes.... Day 1 Now I'm an Aussie, and things look a bit differently from this side of the world. I'm fairly new to the crypto world and only recently discovered BTC and DOGE. How did I end up mining Doges rather than any other crypto? Well, I really don't remember. I remember reading about Bitcoins, bought a “test” usb stick miner on eBay and reading about Đ and how it was “the future”. I vaguely remember stumbling onto a mining hardware comparison website, downloading Cudaminer, randomly picking a pool and watching the (yay!)'s flicker off the screen. But honestly, that seems like years ago. Actually it was just after the halvening – yes, that was it! It's coming back to me now. So today I started looking into ASIC scrypt miners. They're quite the hype on cryptonews and even in our sub. I found a few people on eBay selling them for AUD290 + postage while my fellow shibes in the US of A could lay their grubby digging paws on them for US220. Unfair! So I hopped on the Net and bee-lined for gridseed.com. I'm not Chinese, can't figure out what I want to know – dead end. Read some more reviews and honestly, it will take me 220+ days to make my money back using one of these and that's not even taking electricity costs into account. That's also assuming I get it to run at the hash rates they claim on the promo material. So I did some math. $300 AUD buys me one of these “bad boys”. $300 also buys me Đ300,000 – almost instantly. I have to admit buying it doesn't have the WOW-factor to it and feels a bit like cheating BUT it gives me the result in less time PLUS any growth over and above my purchase price is all mine! Now I only have to get myself so far as to actually make the purchase! It is an investment... Takeaways already cost $36 (AUD) for the family and I have nothing to show for it after 45 mins except an ever expanding waistline and having to wipe the kitchen counter. This will be an investment in the community, an opportunity to do good AND stop the assault on my body! BARGAIN!!
It seems to good to be true, so I'd like to know why.
So I've looked at doing Bitcoin mining for a while now, and I've just had a CPU running on a computer doing mining so far. I came across the clevermining.com pool and it states right now that the BTC/day per MH/s is about 0.000180 (source). Looking at some of the USB ASIC hardware, I came across the HexFury 11GH/s stick. So just looking at the amount of BTC/day I could make: 0.000180 BTC/day / MH/s * 11000 MH/s = 1.98 BTC/day $257.19/BTC * 1.98 BTC/day = $509.23/day I know from reading other sources that you basically need THs of power to produce a few dollars per day in profit, so what I'm I missing in this calculation? Thanks!
Someone please proofread what I have written below, so it can be posted on r/environment and other such subreddits.
Here is the title. Bitcoin requires a tremendous amount of electricity to be maintain, but there are much more environmentally-friendly, alternative cryptocurrencies. Please demand that merchants accept the environmentally friendly alternatives. Executive Summary: Large Bitcoin mining operations are now being constructed in places where they unnecessarily squander the least expensive, renewable hydro-electric and geothermal-electric resources. There are very environmentally-friendly, readily-available, alternative cryptocurrencies such as Blackcoin and NXT that do not pose a threat to these precious renewable resources. The environmentally unfriendly coins that require a lot of electricity to mine are called Proof of Work (PoW) coins. The environmentally friendly alternatives like Blackcoin and NXT are called Proof of Stake (PoS) coins. The price spike in bitcoin last fall has led to an arms race to adopt electricity-gobbling, specialized mining equipment in the pursuit of corporate mining profits. They were not required to maintain Bitcoin prior to their invention. Specialized mining equipment for a second class of coins, which are similar to Litecoin, another PoW coin, is about to start shipping. This will lead to another large surge in unnecessary corporate mining operations and greatly increase the electrical demand in the race for corporate mining profits. You can read the long report below.to find out more about the issue, and you can visit blackcoin and NXT at the links below to find out more about our coins. If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed. Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives. http://www.reddit.com/blackcoin http://us.reddit.com/NXT/ Electrical requirement to mine PoW coins: The Bitcoin, Litecoin, and Dogecoin ledger are maintained by miners who compete against each other to see who can first find the next page for their blockchains. Only the miner that wins the race for each ledger page gets paid in coins. As a result of this competition and the late 2013 price spike, Bitcoin mining corporate startups are popping up in central Washington State as documented in the first link below to take advantage of the inexpensive, renewable hydro-electricity and in Iceland as documented in the second link below to take advantage of the renewable hydro and geothermal resources. If bitcoin continue to expand, it will unnecessarily eat up more and more of these valuable renewable resources Link to Washington State Bitcoin mining article http://www.spokesman.com/stories/2014/ap26/northwests-cheap-power-drawing-bitcoin-miners/ Link to Iceland Bitcoin mining article http://dealbook.nytimes.com/2013/12/23/morning-agenda-the-bitcoin-mines-of-iceland/?_php=true&_type=blogs&_r=0 The next surge in electricity requirement is about to happen: The mining hardware manufacturers are about to start shipping specialized mining equipment that can only mine the Litecoin and Dogecoin type of PoW coins as documented in the two links below. This new front in the mining arms race will gobble up much more precious renewable electricity in the competitive pursuit of corporate mining profits than is currently required to update the ledgers of these coins. http://www.cryptocoinsnews.com/news/innosilicon-a2-terminator-scrypt-asics-first-28nm-chips-litecoin-dogecoin-mining/2014/04/30 https://coinreport.net/zeusminer-pre-orders-scrypt-asic-miners/ http://www.coindesk.com/mining-roundup-multipools-doge-amazon-ec2-11ghs-usb-sticks/ This specialized equipment is prostituting the original bitcoin promise The tremendously profitable mining of crypto coins that are competitively produced is unnecessarily prostituting the original concept of their inventor, Satoshi Nakamoto. He envisioned bitcoins as being mined on standard personal computers while preforming other useful tasks. Instead, special computer hardware is being manufactured costing upwards to $10,000 apiece which can perform only one task. These individual units are being racked up in warehouses now. This specialized equipment was not required for Bitcoin prior to its invention and is not required currently for Litecoin and Dogecoin. However, it is coming anyway producing an unnecessary arm race in the pursuit of corporate profits. These specialized dev ices are energy inefficient in a second ways. These specialized devices generate so much heat that they require elaborate energy-intensive cooling system for large operation. One of the most elaborate of these cooling systems is documented in the link below for a Hong Cong corporate mining operation that emerges the energy-wasting equipment in boiling goo to keep it cool. Thus, not only does it take electricity to run the equipment for these large operations, but more to keep it all cool. http://www.theverge.com/2013/12/2/5165428/bitcoin-mine-in-hong-kong-uses-jelly-to-keep-cool PoS coins are the environmentally friendly alternative. In contrast, the ledger pages of coins like Blackcoin and NXT are generated by stakeholders who cooperate to perform the task which are being done on standard multitasking computers. Many of these computers would be running anyway as originally envisioned by the inventor of the blockchain. If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin.

Hi! After watching the bitcoin stuff over the last few years from a distance (and kicking myself for not getting involved), I've been delving into cryptocurrencies hard in the last few months- I even built a milkcrate mining rig using BAMT. I am going to point that at a vertcoin pool once I grab another USB stick. For now, I'm just using my main desktop's GPU, feeble and CUDA-based though it may be. Vertcoin strikes me as one of very few alt-coins to offer something unique- a means to have a more even wealth distribution. I think the ASIC hammer will fall on the scrypt coins later this year, so it's nice to know there is a safe haven out there for individual miners without deep pockets. The existence of an easy trading infrastructure means that there is room for a wide variety of currencies to be in circulation and I believe that Vertcoin will have a solid place among them.
