That was incredible yet unbelievable story of how the person that the OP have mentioned accumulated such a big amount of Bitcoin even without putting up an investment through fiat and those have gathered only by just donations. Maybe at that time Bitcoin was just a small amount compared for today and if that person have managed to take into hold with those Bitcoins for years since accumulation, he would really be a multi millionaire as of the moment that Bitcoin's price have boom compared to what it have before.
