Cgminer is the best mining BitCoin softwares than any other mining softwares ! How to work with Cgminer ? First, you need register an account at a mining pool. There are a lot of mining pools out there. If you choose BTCguide as your mining pool, after you register on BTC Guild, you have a single worker created automatically, named (username)_1. Workers do not require passwords to mine at BTC Guild. We recommend entering '123' as your password when connecting, since some miners do not function without a password. Launching cgminer, you will be prompted with the following: URL: stratum.btcguild.com:3333 Username: username_workername (example: eleuthria_1) Password: 123 (or leave blank, it does not matter) In case you don't want to enter command one per line, you can save command to .bat file (such as cgminer.bat) and run it from promt windows. /*------------------ Here is a simple example of cgminer.bat ---------------*/ @Echo off cgminer.exe -o stratum.btcguild.com:3333 -u username_workername -p 123 /*--------------------------------------------------------------------*/ You can use many other arguments for tweak your command for suitable with your video graphic card.
