So I was also mining in 2012ish and I had a Butterfly Labs piece and a HashFast Baby Jet. At one point I had 70 BTC but I sold them all long before BTC broke 1000.
The pool I used was the Eligius pool aka LukeJr's pool.
In 2012 until 2014ish I was getting small payments of BTC every day - like .01 - .10 BTC, but then eventually difficulty and electricity made it unprofitable. I still have the HashFast in storage but it's basically an expensive paperweight at this point.

The upshot of Eligius pool was that you didn't need to register for an account. You could just have an address and then the coins were mined directly into it.
