Bet adjustment is actually about the management of risk and emotions. Pursuing after losses through bets increase can be potential danger, because a single wrong turn can erase you. Increasing after a win may feel safe, if you will be betting with the profit, yet it can as well backfire when the streak stop abruptly. From my view, I will prefer staying with consistent bets with slight adjustment, because stability provides better chances of lasting longer to avoid tilt. The concern is securing your bankroll at first, not going after fast swings.
Risk management is extremely important in gambling, and this means that you should stick to a fixed stake (or with a slight deviation that is allowed). If you start increasing your stake for any reason without increasing your bankroll, this will lead to losing more than originally planned. Significant losses will make you think about trying to recover, and if you have the habit of raising your stake, in the end this will result in losing your entire bankroll.
