I am not interested in mining myself, I just want to know how true my friend's claims are since Bitcoin is a subject that I try to follow and understand.
He says he mined 31 bitcoins in 7 months using 2 gtx 460 in a regular gaming PC. This supposedly happened around 2011-2012. I told him this sounded like too much to me and he says it was possible because he was in a "hard to access" mining pool.
So, I just want to know if these numbers are remotely possible. My limited knowledge and the browsing I have done says it's too much but, of course, I could be wrong.
What do you guys think? Thanks.
