I wasn’t aware of the risk management while betting, I thought it was kinda reserved just for my trading activity, thanks God I din not lose that last roll, but as I mentioned. I never played anymore...
Risk management is useless in gambling with luck-based games. It does not matter if you place a bet with 1% of your gambling wallet or 100% you still have the same odds of winning and reward if proportional to risk. Risk/money management is necessary only with games in which your opponent does not have statistic advantage over your. F.e Poker.
That's why we have professional Poker players and 0 professional roulette players. Because with luck-based games there is only one factor that determines how much you win/lose - that's luck.
