For me anytime i play games on casino or placed some betting on sportsbook i always do with 1 condition. I will withdraw if i already got 2.5x bankroll (150%ROI). But i only withdraw my profit, and i will play again with my initial bankroll until i tired/sleepy/loss.
So atleast if i lost my bankroll after i withdraw my 150% profit it will make me got 50%ROI
