It was Paypal President David Marcus that said "The big question is whether [Bitcoin] is going to go mainstream or stay limited to just a few zealots and criminals."
Classic bitcoin bashing from Paypal. They have the most to lose from the rise of bitcoin, so it's only logic. Someone should tell M.Marcus that the vast majority of bitcoin users are legit law-abiding citizens. Saying the opposite is like reading drunk driving stories in the newspaper and claiming that all drivers are drunk.
