Good guy, bad guy... The distinction is blurry in the business world. I would probably think Zuck wasnt that bad if i met him on the street. He probably isnt that bad at all.
The problem is the philosophy behind it.....
But really... He cant corrupt crypto, he can only help it. If he can bring mainstream adoption, i couldnt care less if he made Coinbase into a "give me your fingerprints, your DNA, and your pets name"... I just wouldnt use it...

... but the news that he bought Coinbase would rock the world
