Here is how it happened.
So massive win by MrBrigtside on blackjack private table! I really admire him in terms of how he control his bankroll even when he is on lose streak. He is very patient on playing multiple seat and his bet size increase timing is so perfect. I wonder if this guy experienced loss 100% of his bankroll on his single bad game because he seems the type of guy that will stop playing when he loss a specific percentage of bank roll then just come back again on the other day.
Blackjack is indeed a profitable game if you will just be patient and follow the basic strategy as much as possible without being greedy or chase loss.
I believe that time was the reward is so massive too for all the tournament in the casino which is why high roller can risk huge amount easily because of the possible huge return when they won the tournament. IIRC, 2BTC is the total prize pool on daily while hourly and weekly is different too.
