Kinda impossible to beat the dealer, specially with this kind of amount.
5k for the smallest one... to have played a lot to your blackjack and won and LOST important amounts, I never reached even the smaller level of 5000 of gain, even when playing at max bet of 400 steem during more than 1 hour.
So ok I'm really wondering if you will have even only 1 person reaching the smallest reward...
