you guys forget or don't know the whale bet 7000btc per roll on just-dice, that's the story in 2013, and he rolled the probability of 96% win. that's insane
and don't forget hufflepuff on primedice won over 2k bitcoin. but no doubt 7k bitcoin worth $800k at that time in single roll was insane and sure its biggest bet and won.
Unfortunately the 7k btc bet on jd was not a win.
Saw this on 777dice:

Biggest bet: 12,569.000 mBTC
Is that a bet of $4.984 ?

Yep that's a $5k bet/win?
