In the first place why he claimed to be satoshi, what are the advantages. If he is satoshi, then make a transaction from the btc address used from the genesis block.
If he manages to confirm people, and then mainly this whole industry that he is Satoshi, he could pretty easily find himself be asked for plenty of positions in various influential businesses here.
If he has even more shady plans, I am sure that he could extend his position abuse even further to bank on something big. He however made a fool of himself by acting shady and not providing actual public evidence.
Gavin believing that he is actually Satoshi just shows what kind of idiot he is, and that he is a shady entity as well. It's mind boggling how a once respected high level Bitcoiner managed to sink that deep.
