1. Considering current BTC adoption worldwide, which is around 0.001% of all population. All people dealing with BTC nowadays are early adopters. Even with the "price" of $1000 per 1BTC.
2. If BTC is going to be global currency, some simple math:

- approx. amount of all FIAT money in the world = $75 000 000 000 000
- max available amount of all BTC = 21 000 000
- potential highest value of BTC, if it replaces FIAT (never to happen) = $75 000 000 000 000 / 21 000 000 = $3 571 428 per 1BTC

Actually that number is irrelevant. With wider adoption BTC won't be usable unit for regular people, it will be mBTC, later on μBTC, later on nBTC, later on pBTC.

So yes, if Bitcoin is here to stay, all early adopters (including those buying today) are the new wealthy elite.
