Out of curiosity, I traced some of the whale's payments through the bitcoin network, and very quickly found about US$3.5 million still sitting unspent in bitcoin wallets.  If the whale were really a pool, then he would have had to pay much of that out to miners.  So it seems that he is indeed a very large farm as he has mentioned, likely with installations located in Guangzhou, Beijing, and Shanghai -- which suggests very strong backing as it has not been necessary for him to convert that much bitcoin into fiat currency in order to cover expenses.

And with all that money, he only donated $63 to Wil for wafflestats.  Well, it's better than nothing I guess!
