I think he's getting 10mil over 4 years, stated in the chat (I might be wrong). Which is a pretty fair number. He has already given some of his personal coins too, actually

With 50% being granted freely to the public, I think you yourself could easily amass 10million over 4 years :)

The foundation also made it very clear that the pre-sale of coins was being used to fund the project, many projects (such have EOS) have used a similar model. Therefore, the pre-sale price, and the current price are not linked at all -- anyone who bought in with a different idea should have listened to the interview with John on @bluerocktalk or done a bit more research.

The gesture of buying the coins off the market was done as a good faith gesture to appease the miners and keep the price at what he believed to be a fair range for the current. He also believed he was getting the coins at a low price, and if what he says is true about the future.. it probably is.

He purchased so people wouldn't lose faith too early in this project which has a lot of promise -- but in a market where people tend to lose faith and interest quickly, spreading FUD and Doubt for literally no reason. People are not happy with anything they get.

As always, investing is done on a personal basis, and if you didn't know these things before purchasing in a few weeks ago, you were not making an informed decision.

Thanks for your reply, cheers!
