BitMinter

Bitminter is one of the old mining pools from 2011.

Mining was technically difficult in the early days. A mining client had to be run from the command line. Most people don't know what a command line is. The original idea for Bitminter was for an easy-to-use graphical mining client that anyone could use. This was for mining on graphics cards initially. As client development neared completion the project eventually turned into a full mining pool which launched June 26, 2011. As the first generation USB-based ASIC miners arrived in 2013, support for some of these were also added to the Bitminter client.

The coinbase signature for this pool is: "BitMinter" [1].

Mining servers for Bitminter are available in the US, Canada and the EU.
