Not all high rollers are early adopters, some of the high rollers buy bitcoins to gamble. he might've bought it who knows, we can't say for sure.

So do you really think that millionaires will sit in front of a computer and play millions of dollars worth of coins which they invested ,i really do not think so,they will head out and play in a real casino if they are dealing with millions of dollars and most of the players online who wage big amount of money are actually early adapters . Congrats on the crazy win.
