I think being an early adopter is in no way a good guess about him or her having a lot of bitcoins. The thing is that the community was really very noobish when it comes to investments and scams. Practically every early adopter lost a lot of coins to scams, bad investments or inept businessmens. And if that did not work then they built their own projects that turned out to be not that successfull.

That is because many early adopters left or became quite calm.

It's a pain that the bitcoin community is so very dangerous. At least a lot was learned and it's possible to try to stop scams from happening. That's, by the way, why i do the escrow service.
