Bitcoin is a digital decentralized currency that is getting hot these days.One bitcoin, as of this writting, worths about 520 US dollars.It has been recently legalized by California.Bitcoin can be earned by helping verifying transaction, aka, mining.Mining is essentially computing hashes, many many of them.This article will walk you through how to start mining bitcoin with a graphics card on a commodity PC.The first step is to setup a wallet to store your money(Bitcoin).There are a bunch of choices, you can choose to setup a local wallet on your computer or choose a online service.I chose to use coinbase because it’s easy to setup.You will get a bitcoin address like 1NpnrNH12JGLhCdHrMLSZhNptnVVPfvafy which identifies a digital wallet.It can be used to send or receive bitcoins.You will work with a group of other miners by joining a pool.A list of available pools can be found here.I chose the Slush’s pool as an example.After setting up your account.Put in your bitcoin address in the My Account page.

In the same page, you will find one worker has been created.gold bitcoin pendantIts login and password will be used later by the miner.bbc bitcoin 1000One worker is needed for each miner you setup.cours bitcoin 10 ansThere are a lot of miner options.bitcoin mine ubuntuYou choose a miner based on your hardware and operating system.bitcoin fmiVarious kinds of hardware have been used for bitcoin mining, for example: CPU, GPU, ASIC, FPGA, etc. My desktop PC is running Ubuntu 12.04 and has a radeon HD 6670 graphics card.bitcoin hydroThere is a post about setting up CGMiner on XUbuntu.

Not all the instructions work for me, so here is what I did for your reference: Download the driver from here.Follow the instructions in the installer.Check your card can be found by: You are expecting this as output: Note: You’d better don’t use newer version of cgminer since versions after 3.7.2 don’t support GPU anymore per this post.Write a shell script to run cgminer: Cgminer looks like this when it’s running.You can find your current hash rate, GPU temperature and many other information.Bitcoin mining speed is measured hash rate whose unit is Mhash/s which means million hashes per second.That number largely depends on the hardware used.My radeon HD 6670 is working at about 90 Mhash/s.You can find the speed of different hardware from here.Specially made ASICs have much faster hash rate than GPU and CPU.You can calculate the earning of mining using this tool.At my current hash rate, I will earn about 3 cents per month :( So don’t expect making money by mining from your personal desktop.

You should consider purchasing those much more efficient ASICs.bfgminer: multi-threaded multi-pool ASIC, FPGA and GPU bitcoin miner bfgminer-dbgsym: debug symbols for package bfgminer Versions published Release The package versions that were published when the distribution release was made.bfgminer 5.2.0+dfsg-1build1 () bfgminer information Current version: 5.2.0+dfsg-1build1 Uploaded: Urgency: Upstream connections BFGMiner ⇒ trunk Modular Bitcoin miner Bug supervisor: Bug tracker: Branch: There are no registered releases for the BFGMiner ⇒ trunk.Show upstream links Releases in Ubuntu 5.2.0+dfsg-1 5.2.0+dfsg-1build1 5.2.0+dfsg-1build1 Binary packages bfgminer-dbgsym (amd64) (arm64) (armhf) (i386) (powerpc) (ppc64el) (s390x) bfgminer (amd64) (arm64) (armhf) (i386) (powerpc) (ppc64el) (s390x) Download files from current release (5.2.0+dfsg-1build1) File Size SHA-256 Checksum bfgminer_5.2.0+dfsg.orig.tar.xz 845.0 KiB 28dc28076561405bbd47635873b97823fa9ff0ac1e3cf08b6585489fa3681da4 bfgminer_5.2.0+dfsg-1build1.debian.tar.xz 12.0 KiB f31fcd7c870381bc23c177e69ceace60d5546ef74be44a7defd7f396e4fa862f bfgminer_5.2.0+dfsg-1build1.dsc 2.2 KiB 2ee87a46fef03539ec9a29c99c42c42a4d93ee41bfdbc72ed2dd4b3e99435753 Package relationships Build dependencies debhelper (>= 9) dh-autoreconf help2man libbase58-dev (>= 0.1.4) libblkmaker-0.1-dev libcurl4-gnutls-dev libevent-dev libjansson-dev libmicrohttpd-dev libncurses5-dev libsensors4-dev libudev-dev libusb-1.0-0-dev pkg-config uthash-dev Platform-independent build dependencies Platform-dependent build dependencies Build conflicts Platform-independent build dependencies Platform-dependent build dependencies
