What if he is working on something new? Something that would outshine Bitcoin??
I think he is not working on anything new, since he is allready rich, first few thousands of BTC mined are his, i'm sure. This can be checked somehow i guess, who was the first miner and how much did he mine so far ?
That's not exactly true. Right now there a lot of exchanges open that would easily be able to deal with 50-100BTC which would easily suffice for the short term day to day costs. We don't know all of his addresses and as long as he does not withdraw excessive amounts very rapidly it'll be hard to track him down. A couple hundred of BTC over the course of a year would make him quite comfortable without drawing too much suspicion provided that the trades were done in regular small amounts.
Unless its so very few, the amount of Bitcoin days lost would be very significant and someone would notice.
And even if he traded at an exchange, any exchange, unless he trades straight crypto to crypto it would be VERY hard to conceal his identity.
