Just noticed that the #1 miner on Dwarfpool hasn't sold a single ETH he mined in the last 2 weeks.
He has 76000MH/s so about ~4000 GPUs or so.
He started on April 17th and the ETH aren't transfered to any exchange but to his personal wallet.
Daily he makes around $7000-8000 and is currently sitting on 6500 ETH so about $50,000 worth.
Either he knows something, is stupid, or has balls of steel.http://dwarfpool.com/eth/address?wallet=23886517f1c818412505066a9d3f10792783d869&allpayouts=1https://etherchain.org/account/0x23886517f1c818412505066a9d3f10792783d869#txsent
