The good news is that you can purchase purpose-built mining hardware that will mine Bitcoin. While potentially profitable, there are several caveats. ASIC mining hardware is backordered, expensive, power hungry and loud. I backordered a 5Gh/s and a 25Gh/s ASIC (both pictured above) from ButterFly Labs in May and just got them this month, a six month backorder. If you're serious about getting into Bitcoin mining I suggest that you either purchase a BFL miner on eBay, or place a pre-order for one of the rip-snortin' fast 300 or 600Gh/s miners that Butterfly Labs will begin shipping in January.

To monitor your progress, log into your mining pool account and watch the "My Account" page. I have Slush's Pool set to transfer my BTC rewards to my wallet every 0.1 BTC (the "Send threshold" below) and as you can see by the screenshots, I've been getting 35-36Gh/s hashing performance from my two BFL miners pictured above. At 36Gh/s I've been able to mine 0.1 BTC every four days and I'm on a pace to mine 1BTC/40 days at the current difficulty level.
The next generation of mining hardware from Butterfly Labs are a pair of PCI cards based filled with 28nm ASICs that are capable of mining at 300Gh/s ($2,800) and 600Gh/s ($4,680) respectively. Orders places today for the new "Monarch" cards are expected to begin shipping in February 2014. KnCMiner, based in of Stockholm Sweden, is taking pre-orders for a 3 Terahash miner called Neptune, only 1200 units are being made and one will set you back $12,995. According to the founders, Neptune can mine 2.1 Bitcoin per day at current difficulty levels.
Has anyone successfully set up a miner on Mac OSX? What are the most recent mining clients that will work on my 2011 MacBook Pro? I've tried DiabloMiner and poclbm but can't seem to get them running. I'd rather have a command line client if possible. Also, on what basis should I choose a mining pool? Can anyone recommend any and why?
Been using the Open Source MacMiner for over a month...:-) This mining GUI is mining engine agnostic because it natively supports bfgminer, cgminer and cpuminer/(minerd) under the hood on Mac Platforms. This GUI interface is mining pool agnostic because it can effectively interface to centralized pools and natively supports decentralized pooling, i.e., P2Pool.
I've exercised bfgminer functionality associated with MacMiner's "BFGMiner" and "FPGA/ASIC Miner" views using both the STM and GBT protocols at a number of different pools (e.g., the usual Centralized Mining suspects: BTC Guild, BitMinter, EclipseMC, Eligius...; Decentralized Mining: P2Pool through the Fabulous Panda P2Pool Service Provider and others). Albeit, not all pools support both STM & GBT. I've exercised minerd/(cpuminer) functionality associated with MacMiner's "CPUminer" view for mining Litecoins, but not recommended for Mac Mini - overheats unit. (You can guess what miner the "CGminer" view executes. Need time to exercise this functionality.) The performance of multiple ASIC devices can be seen from the "API Output" view. This Mining software is still a little rough around the edges, but software updates are automated, and require your approval.
Once MacMiner is configured and running, you can "ps -A grep bfgminerminerdcgminer" and you are off to the races building your own JSON config files (typically residing in your /Library/Application Support/MacMiner directory; examine the bfgurls.conf & ltcurls.conf files written when you save your pool settings) that can be used to execute the miners (i.e., bfgminer, cgminer, minerd) with a text terminal. Check out an alpha HOWTO for using MacMiner's bfgminer functionality at =Tutorials:HOWTO+Install+and+Run+MacMiner-+Version+0+9-alpha.
One of the most popular and best-rated software for mining Bitcoin is CGMiner. It's available on Windows, macOS, and Linux, making it an extremely versatile option. The software is an open-source project written in C. This is an ASIC/FPGA miner that includes support and binaries for RPi and OpenWrt routers. CG Miner is filled with great features like overclocking, monitoring, fan speed control, and remote interface capabilities. It can detect new blocks with a mini-database. It also supports binary loading of kernels, multi GPU support, and CPU mining support.
BFGMiner is a modular ASIC/FPGA miner written in C, featuring dynamic clocking, monitoring, and remote interface capabilities. This software is compatible with FPGA and ASIC mining hardware. When you use BFGMiner, you'll be hash on the most popular mining algorithms like Scrypt and SHA256d. You can even use BFGMiner to mine multiple cryptocurrencies at the same time.
MultiMiner is a desktop application for crypto-coin mining and monitoring on Windows, Mac OS X, and Linux. MultiMiner simplifies switching individual devices (GPUs, ASICs, FPGAs) between crypto-currencies such as Bitcoin and Litecoin. MultiMiner uses the underlying mining engine (BFGMiner) to detect available mining hardware and then presents an intuitive screen for choosing the coins you'd like to mine. MultiMiner was designed from day-one to cater to both new miners and power users. From the Getting Started wizard to MultiMiner Remoting, you can be certain you've found the Bitcoin mining software to fit your needs.
Asteroid is a free, open-source graphical frontend to CGMiner for Apple Mac computers, whose focus on simplicity is intended to be approachable for new users. Asteroid supports the same devices and features as cgminer, and adds additional features such as crowdsourced scrypt settings, coin address balance monitoring, a pre-populated list of common mining pools, and MobileMiner support for controlling Asteroid from a smartphone.
Precompiled universal binaries for cgminer and its dependencies (libusb, libjansson, and curl) are included. Thus the installation process for end-users is straightforward, involving only downloading and decompressing Asteroid.
All three of the most relevant mining backends are included in this mining software, bfgminer, cgminer and cpuminer. This gives the user the flexibility to choose whichever runs faster for their setup, whether they're CPU, GPU, FPGA or ASIC mining Bitcoin, Litecoin or any compatible Alt Coin - including Dogecoin, VertCoin, QuarkCoin and MaxCoin - faster than an asteroid. Each miner window has a full set of tailored options for ease of use and there is a detailed API Output window which even allows one to monitor other miners on the network that are using cgminer or bfgminer.
MacMiner is a versatile, yet quite intuitive to use bitcoin miner for the OS X platform designed to offer a convenient and native graphical user interface that replaces the sophisticated command line based tools, which Mac users generally use for bitcoin mining[1].
When opening the MacMiner app for the first time, the BFG Miner window will be displayed by default, while the other miners can be accessed through the View menu or using keyboard shortcuts for all miners. In addition, although each mining window is separate, you can monitor all of them from the API Output window.
The software includes overclocking, monitoring, fan speed control and remote interface capabilities, among others. With ASIC, FGPA & GPU and multi pool support, CGminer is more than an adequate solution to handle your mining operation.
Besides being a super versatile program, BFGminer is also cross platform, including an option to install on Raspberry Pi which is pretty neat. Though text based, the interface is very straightforward and you can use hotkeys to go through the different options it offers.
Lastly, BFGminer has a watchdog thread to detect idle threads and restart them or stop failed reconnects to spare your resources. Among the ASICs supported by BitMinter you could find Antminer U1/U2, Block Erupter USB, Red/Blue Fury and more.
Only the cyber criminals who successfully trick users into installing cryptocurrency miners benefit from this process. If a miner has been installed on the operating system unintentionally, remove it immediately.
These instructions describe the installation of the Silicon Labs CP210x USB2Serial driver, the installation of the adapted BFGMiner version for the Moonlander 2 USB stick miner as well as the setup of the mining software with a mining pool. For Mac OS systems we provide a 64-bit binary version for download.
For beginners we recommend registering with a Litecoin pool or the mining pool of another Scrypt-based crypto currency. We have had good experiences with litecoinpool.org and Nicehash and can recommend both of them.
You can set the clock rate of the miner with the following command line parameter. As a start, a clock rate of 600 MHz is a good compromise between performance, power consumption ageing of your miner.
Please note that this version of the miner has a fixed list of frequencies available to use below: 384, 450, 480, 540, 576, 600, 612, 625, 636, 648, 660, 672, 684, 700, 720, 744, 756, 768, 796, 832, 852, 876, 900, 924, 954.
Please note that higher clock rates cause a disproportionately higher power consumption. Your USB port or active USB hub must be able to provide the requested power, otherwise malfunctions will occur. Furthermore, high clock rates result in a high level of heat development, which is associated with a reduced life expectancy of your miner.
One note in advance: The voltage adjustment may only be carried out very carefully and in small steps. Under no circumstances may values be set above or below the bandwidths specified here, as this can damage the ASIC chip. Please note that a miner damaged by faulty fine adjustment will not be replaced by us. The voltage is adjusted at your own risk.
By 2011, Bitcoin mining was largely performed by GPUs. This raised concern in some users that mining now had a high barrier to entry, and that CPU resources were becoming obsolete and worthless for mining. Using code from Bitcoin, a new alternative currency was created called Tenebrix (TBX). Tenebrix replaced the SHA-256 rounds in Bitcoin's mining algorithm with the scrypt function,[10] which had been specifically designed in 2009 to be expensive to accelerate with FPGA or ASIC chips.[11] This would allow Tenebrix to have been "GPU-resistant", and utilize the available CPU resources from bitcoin miners. Tenebrix itself was a successor project to an earlier cryptocurrency which replaced Bitcoin's issuance schedule with a constant block reward (thus creating an unlimited money supply).[10] However, the developers included a clause in the code that would allow them to claim 7.7 million TBX for themselves at no cost, which was criticized by users.[12] 2ff7e9595c
