So I definitely cannot speak to any association he had you'd have to ask him. Not sure on the timelines either. He was definitely not the co founder of Cryptsy haha.

According to Marshall Long he is, or does Cryptsy allow anybody to claim to be a co-founder of Cryptsy sans evoking a cease and desist order?

Went from Cryptsy co-founder to trying to bed Josh Garza at $150/trick to CTO of Cryptsy to CTO of Mintsy to investor to no longer CTO at Cryptsy to Paul Vernon thanking Marshall Long for not having to repay the investment.
