I know it may sound crazy, but given the fact that Vitalik is one the most smartest programmers in which he created the Ethereum platform himself (also with a very complex system) it makes me think whenever Vitalik may be Satoshi or not?
There is a team behind Ethereum and he didn't made it all alone.He might be the leader or the one with the idea but there is a difference when people work with a team behind them to backup and when they are independent developers clearing doubts online.
anyways,There is no suspect other than theymos himself to be the inventor of bitcoin.The "satoshi" is just drama IMO.
