But don't you think that if you find Satoshi, you'll ruin his life?
That's why I don't speculate publicly any more about Satoshi's identity. He deserves his anonymity, very much so. (I do have a clear opinion as to the best candidate, just not voicing it.)
Against the notion that Satoshi was a team, I pretty strongly believe that it was a single individual (albeit one who was well aware of the many failed attempts that pre-dated bitcoin). Part of my conviction is that it is much less likely that multiple people have managed to keep the secret this many years. But the biggest reason is that I'm convinced a single mind had to conceive of all the working parts and visualize how it all worked and was robust against any fatal flaw. Committees can improve pre-existing things, but it tends to be lone inventors who make the breakthroughs that are famous in history.
