I was looking at https://blockchain.info/address/1Fd8RuZqJNG4v56rPD1v6rgYptwnHeJRWs Stefan Molyneux's bitcoin adress :

Total Received   652.94530317 BTC   

Final Balance   521.24590891 BTC

He accumulated quite a lot of bitcoins through donations, it will eventually buy a lot in a few years and it is incredible. Do you have other stories of people accumulating large amount of bitcoins without investing any fiat ?
