I think the most remarkable thing on that Leaderboard is not Hufflepuff but the guy who managed to make 110 coins profit with just 147 bets. This is what I call luck
Probably just starting with a bankroll that's large profited them that amount. You also have to remember that early adopters of Bitcoin could have mined a pretty large amount and played in Primedice in its
prime (heh heh) and used their large sum of bitcoins there. Hey, I think we know who the real winners here are, though. Primedice. Imagine the huge amount of money they earn, with all the traffic and gambling. Look at the losers leaderboards. Wow! Insane.
What's really stupid is seeing people unaware of how Hufflepuff cheated. Psh... comment away, spam the same thing about the "massive win" from Hufflepuff without reading anything first.
