I ended up getting 2 AMD Radeon 5970s with the bitcoins I was exploiting, but at the time, the OpenCL libraries from AMD and nvidia were all really buggy and I could never work properly with Many GPUs. I also did work at the time and so I never finished it. I ended up leaving only a bitcoin on the record drive for a few years, then it exploded and people started asking me about the merchandise trades. I am a Bitcoin millionaire, I can tell everyone the same thing, to make myself a little interesting hacking target
