I'm thinking about getting into hobby mining and I'm wondering what type of setups you guys have.
Well, there are only two manufacturers of Bitcoin miners, Bitmain and Avalon. Not allot to choose from.
Is there are reason for this? Are these miners built specifically to mine Bitcoin, and if so how? How do you build a computer specifically to mine Bitcoin and not for any other applications? Also, I thought there were more companies doing this back in the day. What happened to them?
