I don't know anything about mining bitcoin is possible past few years ago..I just bought it and do some exchanges to complete the level in my games or to get extra things to improve the game that I was playing. Now regret is all I have if only I knew that bitcoin is a valuable thing that can be change as currency I'm not going to be stupid enough just to waste all of em ...haa I try to find a way to recover just by mining using my pc and gpu..cheers
