Without that though you might spend a lifetime making one coin. When you get much over 0.3 Mh/sec you need forced air cooling and it goes downhill from there. Technology costs decrease but a multi-ASIC mining rig isn't something in much demand so nobody puts much money into improving them. Mining difficulty, by design, increases with the number of coins mined. If it were easy it wouldn't be a currency. Something like solar powered ASICs are about the only thing feasible. ![]() ![]() I worked for several days to get 5 machines online running cpuminer and realized if I ran them for 20 years I might make one litecoin worth $12. minerd -o stratum+tcp://us.:3333 -O ab1jx.3:3Īnd one of the first things you learn is how futile it is. You don't remember all the options of course, you start it from a script like: h, -help display this help text and exit V, -version display version information and exit c, -config=FILE load a JSON-format configuration file B, -background run the miner in the background S, -syslog use system log for output messages P, -protocol-dump verbose dump of protocol-level activities q, -quiet disable per-thread hashmeter output no-redirect ignore requests to change the URL of the mining server no-longpoll disable long polling support coinbase-sig=TEXT data to insert in the coinbase when possible coinbase-addr=ADDR payout address for solo mining Long polling is unavailable, in seconds (default: 5) s, -scantime=N upper bound on time spent scanning current work when T, -timeout=N timeout for long polling, in seconds (default: none) R, -retry-pause=N time to pause between retries, in seconds (default: 30) r, -retries=N number of times to retry if a network call fails t, -threads=N number of miner threads (default: number of processors) cert=FILE certificate for mining server using SSL p, -pass=PASSWORD password for mining server u, -user=USERNAME username for mining server O, -userpass=U:P username:password pair for mining server a, -algo=ALGO specify the algorithm to use Bitcoin uses SHA256, litecoin uses scrypt, cpuminer can do both, and parts were written in assembly language. A little playing around at CPU mining could help you decide. But an ASIC is dedicated hardware, a bitcoin ASIC can't do litecoin, you have to make up your mind before you invest. A Pi with bfgminer controlling one (or a few) of those would work fine. Cute little $30 ones are controlled over USB and run on like 15 watts. Don't bother with cgminer or bfgminer in the Raspbian debs, cgminer doesn't do litecoin anymore and bfgminer doesn't mine with a CPU as configured.Īnd buying an ASIC isn't a huge investment necessarily, look on eBay. There's no binary for the Pi but you just need mostly libcurl then it's the standard configure and make. For CPU mining cpuminer is what they recommend. There's even a profitability calculator based on how fast you can do work and how much electricity costs to run your hardware. Of course, the Pi is hopeless at a crypto processor for Bitcoin mining, but it is absolutely ideal, with its low power overhead, as a controller for ASICs running software like CGMiner for example.Ĭook_Trading_Chart_Long Term_6 months.gif (16.24 KiB) Viewed 14755 times Start in a shared pool, you are guaranteed to earn some money, there are several reputable ones to choose from. That's speculation for you, could as easily happen with company share stock. It had been over $1000, and it's not beyond imagination that events might take the price well beyond $1000 or it may just collapse to nothing. But the real interest is not in the current price, but speculatively what may happen to the price in the future. It's not true that you can't make money on it, if you get your ASIC devices reasonably cheaply, and find a source of cheap energy then like the thousands of people involved there is a bit of pocket money to be made. Although 1 btc was over $400 dollars a year ago, the Bitcoin spent a long time at about $200, currently it is around $280 at the time I am writing this email. The price of a Bitcoin is actually a bit higher lately. ![]()
