Be this whale a bit more patient, I think he could do the same transaction with fee under $1.
IMHO there is not much to be so exited about.
I remember playing Satoshi Dice game, flipping 0.003 BTC back and forth every 30 seconds. With fees close to zero, maybe $0.00000001. BTC transaction is nothing more than a text message. It's cost to propagate is the same wether it is containing almost $0 or carrying multi billions of USD
