There are not many high rollers that play like that. We've got a max win of 20 BTC per roll so they would have to go 1.2x with a 79.17% win chance. Need some balls to do that.
Do those HRs mainly Martingale? Palms be sweaty, knees weak, arms are heavy each time the bet is doubled.
Depends on his stack I think. You shouldnt stick to Martingale if your bankroll isnt huge or you may get wracked in no matter of time. Imagine he starts with 1 BTC and has a loss streak for eg 5 games. He would have lost 1 + 2 + 4 + 8 + 16 BTC at the blink of an eye.
I know that in good old times there were so many whales betting huge amounts of coins at freebitcoin
I saw 1-5 btc bets fly , but it was when bitcoin price reached 200$ , so then it was 200-1000$ per bet
today an 0.01 bet is considered HR and I don't n see people bet 1 btc at freebitcoin anymore , maybe because the whales migrated to
the sites with a lower house edge , maybe because there are less people who got their coins close to nothing , cheap
and martingaling with a 1 btc base and a 20 btc cap is suicidal , you get five reds in 2x every hundred bets or so
