如何快速挖到Bitcoin比特币？

利用显卡的图像处理器(GPU)计算Bitcoin大大提高了计算速度，所以现在通过Bitcoin比特币官方客户端的CPU计算已经很难发现一个新的Block来获得50个BTC，一台普通个人电脑可能需要2年时间才有可能一次性计算出50个或25个新比特币，所以参与集体挖矿(mining pool)，稳定小额的获取BTC成为更现实的选择。因为CPU计算效率过低，官方客户端从0.3.22版起取消了计算比特币的功能。
下面介绍如何在Windows上利用CPU/GPU参与集体挖矿以获得BTC。按目前的计算难度，一块ATI 5750显卡可以每天获得约0.2个BTC。

安装官方客户端
首先要安装Bitcoin官方客户端以获取你的收款地址(Address)，BTC 协议鼓励每次收款使用不同收款地址以保持不可追踪性。这里的收款地址相当于你的一个收款帐号，而每个人可以有无限多个收款帐号，官方客户端会自动汇总你所有地址中的款额作为可用总额。
安装、运行Bitcoin官方客户端后，程序会自动计算出你的私钥并生成第一个收款地址，以1开头的一串字母和数字组合，如 1AhNWp14rNUoWgwrZNtc9vm586pCVqom3n 。这个就是你的收款地址了。
注册集体挖矿网站
你需要到挖矿网站注册（Register）一个帐号（Account），以便保存你的工作成果和收款地址。目前运作的比较好的有
§ Deepbit（推荐，3%手续费，也可以按每个计算成果付费，即Pay per share模式）
§ BTCGuild（推荐，无手续费）
§ BMP （按积分分配，服务器不稳定会影响收益份额）
注册好帐号后，可能需要点开电子邮件中地址或输入邮件中的确认码，以确认邮箱地址。在网站payment address中填入你的收款地址，比如 1AhNWp14rNUoWgwrZNtc9vm586pCVqom3n 。将minimum payment(最小自动付款额)设置成0.01，以便尽快收到第一笔付款。
然后注册新的worker帐号（挖矿工人进程），因为每个人可能有多个计算机或多个计算进程可以使用，所以每个帐号下可注册多个worker。Worker通常有独立的用户名和密码，worker用户名一般是你的帐号名+自定义后缀，密码简单好记就好，worker的密码被别人知道也没有什么安全问题。注意不要和账户或邮箱密码相同即可。
安装GPU计算程序
下载GUI Miner。如果你有独立显卡，尽可能使用GPU计算程序，因为设计结构和指令集不同，GPU 计算能力一般是CPU的几十至几百倍。如果使用AMD/ATI显卡，还需安装AMD显卡开发包。
解压缩GUI Miner后，运行GUIMiner.exe，选择你注册的挖矿网站，填入你的worker帐号和密码，点Start mining即可开始挖矿。

（File->Save settings保存当前设置。菜单第一项为创建新的Worker。）
使用ATI 5xxx系列显卡计算时，可以在flags里填入-v -w128参数。使用CPU计算无需填写任何参数。
Device为设备列表，显卡通常显示为显卡核心的名字，如57xx系列为Juniper，以及CPU设备。一个设备可以对应多个worker同时工作，程序会自动分配计算能力。即几个不同worker设置使用一个device，同时挖矿。不过对提高效率没有什么帮助……
过1个小时刷新你的挖矿网站页面就可以看到你的预期收益了，等待1天网络确认这次计算即可收款。
Bitcoin 官方客户端运行时会自动显示最新余额。当然，离线时也可以正常收款。下次启动Bitcoin 客户端即可看到收款。
使用BTC付款
在Bitcoin官方客户端中，点击Send Coins即可付款，填入付款地址和数量即可。付款小于0.01时需要支付至少0.0005的手续费，以防止大量付款攻击BTC网络。支付更多则可以免手续费。

Frequently Asked Questions (FAQ):
Q: My window is invisible! What can I do?
A: See here for a solution.
Q: Help! The program crashed or didn't work!
A: If you post a bug report in this thread a variety of helpful people including myself can try to fix your issue. We need to know at least the following: what version of Windows you're using, what graphics card you're using, what version of drivers you're using, what pool you're using if applicable, and a detailed description of what went wrong.
Q: I get an error about "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." or an error mentioning "side-by-side". What can I do?
A: You may need to install the Microsoft Visual C++ 2008 Redistributable Package. Nearly all Windows computers already have this installed, but a freshly formatted computer might not.
Q: I'm having trouble solo mining using the 0.3.22 Bitcoin client. Why?
A: This is a known issue, see this thread for more info. Reverting to 0.3.21 or earlier seems to fix the problem.
Q: How do I know if my graphics card (GPU) supports OpenCL or CUDA?
A: Try running GPU Caps Viewer. It will tell you what your GPU supports.
Q: How do I use the Phoenix/phatk miner?
A: See this thread for support.
Q: What extra flags do I use?
A: If you have a Radeon 5xxx card (for example 5770, 5890), use '-v -w128'. On CPU you don't need any flags. For other cards ask around.
Q: My temperatures are too high, can I throttle the GPU so it runs slower but cooler?
A: If you are mining using OpenCL you can use the -s flag a value such as 0.01 in order to force the GPU to sleep for 0.01 seconds in between runs. Increase or decrease this value until you have the desired GPU utilization.
Q: Can I connect to more than one pool with the same GPU? For example have a main pool, and a backup pool in case the main one goes down?
A: Yes, you can use the -f flag for this. A value of -f60 or higher in the backup pool's miner will cause it to yield most of the GPU power to miners with a lower f value (default is 30).
Q: Is it normal that GUIMiner uses a lot of CPU when mining on the GPU?
A: No, for most people GUIMiner uses less than 1% of CPU. This is a poclbm issue some people are experiencing - see this post for more info.
Q: Do I need the official Bitcoin client to be open while mining?
A: Only if you are doing solo mining - in this case you are connecting to the client instead of a pool server.
Q: Is there a tutorial for solo mining?
A: Yes, see this thread.
Q: How does performance using the GUI compare to using the command line?
A: They should be identical; the GUI introduces virtually no overhead.
Q: How do I know if I'm getting a good hashing rate for my card?
A: See this topic for a comparison of various cards.
Q: How do I know how many Bitcoins I'll generate with my card?
A: See Bitcoin Mining Calculator to determine this.
Q: I installed OpenCL, but my GPU isn't showing up. Only my CPU is shown. What is the problem?
A: A couple people experienced this issue and were able to resolve it by installing a different driver version. Another person resolved it on Windows XP by upgrading from Service Pack 2 to Service Pack 3.

Q: How can I delete my miner settings, or edit them manually?
A: Miner settings are stored in %APPDATA%\Roaming\poclbm. For example, on Windows 7 this path translates to C:\Users\Kiv\AppData\Roaming\poclbm. The file poclbm.ini inside contains the settings in JSON format. There are also some settings in .ini files inside the miner directory, also in JSON format. No registry keys are used, so removing these .ini files completely erases your settings.

Q: How can I completely uninstall GUIMiner?
A: Remove the GUIMiner folder and the miner settings above, and that will completely remove GUIMiner.

Q: I want to see X feature in the miner. How can I have it?
A: I'm working on new features but I have a full time job and other things to do too - if you want to encourage me send donations to: 1MDDh2h4cAZDafgc94mr9q95dhRYcJbNQo

Q: What does it mean in the summary panel when the shares say something like 1000 (150) accepted?
A: That means 1000 shares total were accepted, including 150 in the last hour.
