Either he knows something, is stupid, or has balls of steel.
There you go, fixed it.
With that much hash power I highly doubt that he is stupid. Anyone can cobble together a few miners in their basement, but that type of operation requires some knowledge, planning, foresight, and obvious capital, not things a stupid person usually has access to.
Balls of steel is basically saying the same as stupid, except the person gets lucky in the end. This is the same kind of distinction as there is between a hero and a fool. A hero runs into a burning building and rescues someone. A fool runs into a burning building and ends up dying too. The result is not based on skill just shit luck.
He knows something. I pick this as the most likely choice. Despite the numerous scam and pump/dump posts all over, Ethereum keeps delivering. Not only in code and tech, but funding other new technologies such as The DAO. It also is being picked up by the big exchanges, Bitfinex, BTCe, and now Gemini. Just today Governor Cuomo of New York announced the decision of Gemini to add Ethereum trading with the approval one of of the toughest states there is for cryptocurrency. It's one thing for it the be approved, quite another for the governor of New York to help announce it.
Listen to the naysayers if you want and give them your coins for cheap, but looking underneath the covers I can see something is afoot, and that something is big.
