An important role that we must always apply in gambling is to have a time limit to be able to stop the game, because if we decide to continue playing, in the end we will lose control and are always curious to be able to win the game
Things like that can actually be self-defeating and even make things worse
Sometimes, limiting the time and money in gambling can be forgotten by many gamblers because they are too busy to play and really have fun with the game. It will tempt them to use more money without them realize and that is happening to many gamblers, including me in the first time I am playing gambling. But if they really care about their money and time, they are always trying to limit it and never break that.
Probably why it's a lot easier to limit one of the two instead of both. It'd probably better to limit money instead of time though, since with time, let's say play for an hr, that means you technically have an unlimited amount of money to spend during that time, while if limited by money, even if you can spend it around by playing low bets forever, that would probably just end up boring you, though that does help if you're in it for the game and not for the money.
I prefer to limit both money and time in playing gambling to help us not to playing gambling too long and only use small money. If you limit the money and use playing gambling for too long, I am afraid that you can use more money someday because you think you are playing gambling because of fun. But I accept it if you only limit the money instead of time because I am sure that you have a plan while playing gambling.
