At some point everyone has posted something stupid, but I wish posts asking what to mine would result in an instant suspension. That said, the correct answer is nothing. There is not a coin that you can mine that you will even break even. You will lose money on electricity. You probably got a "good price" because these things are 3 years old and worthless. My advice would be to find a scrapyard and see what the metal is worth
It's funny I thought the same first thing ... if I wasn't here from the start ... I might abandon the ship. WRONG
Even I lost more than 15 BTC by time and now knowing how much they worth today, I just thought to new coins that can be mined even with old equipment. So I just restarted and mined for EMC2 with ... gues what
2 computers of 6 what I had in past in 2012 with 4xATI 5850 equipated.
Funny no ? I mined 103 coins. You will say it's not enough, I agree but it's a start. Still expect to get scrypt miners and put them to work. The question is to remain at EMC2 or move to other coin in SCRYPT ?
