I've won so many times that I believe I've mastered this game and should start stealing some money from casinos through this game. Do you think I should try my hands on this game with real money? Have you ever made a lot of money and made a casino helpless with this game?
If you know yourself that you can make money on it then you definitely should try it but start at a low money as normal 
.I've played blackjack in one website already but not using real money but their own tokens. TBH, if only the currency that is being used there for gambling isn't their native token I probably won a lot already but sad they only use their native token for gambling. I always win in gambling or I should say most of the time I'm winning and since on that website there is staking feature, I just stake my winnings to get some profit in the long run.
I never tried to play BlackJack using coins like Bitcoin or Ethereum but when all is well and this pandemic is gone, maybe I'll try to gamble some too in blackjack
.
But if you are winning a lot from a website then you should never invest in their bankroll because you are supposed to make profits when players lose on their side so just take away your money if you won big.
