This guy's got some balls. Martingale is never an option for me. What if he got one more red after that 80btc bets he hit the max amount you can bet and boom will take alot of hours to recover that back. But congrats to that guy he won

Yeah, martingale can be quite deadly when it fails on you. In fact, there was quite a deadly red martingale on BitDice today and profit shifted up by about 200btc
