The game is insane winning but the gambler in the subject is not the first person to have won something huge like this from a cryptocurrency casino and if you are a follower of Bustabit there's also a well-known user, high roller and wager which usually make and won an insane bet in the crash game (I don't remember his name now) but he seems to be from Asia.
Having said that, this kind of winning is paid weekly or monthly that's why the winner is elevated to VIP5.
