I also think that it doesn't really matter who he is...No matter who he is from the below there will always be two sides of looking seeing things for people to buy or sell..
1. the NSA (+it must be legitimate so there will be mass adoption buy, - they did that to follow our transactions sell)
2. Bill Gates (+it is Bill Gates so it must have value buy, - this fucker got even richer sell)
3. The Pope (+it is a religious coin that unite people buy, - religion did it again and got into finance sell)
4. Bytemaster (i can see only + in that
5. Me (+we had a genious in our community)
etc... so in the end of the day it doesn't really matter who he is... all that matter is if his fortune will be sold out at some point or if this a lost treasure for ever and therefore bitcoin supply is less than we think..
