Point-1 to remember is that not all crypto coins are 'Bitcoin'. Bitcoin is a specific coin with very specific hardware needs which is very different from the hardware other coins use. The other coins are in general called altcoins and they have their own areas here so when you start posting hardware questions be sure you post in the correct area.
