First of all, this is risk management and money management. The second is probably unsystematic play. Let me make a reservation that I do not mean casinos, as well as people playing "for fun". I mean sports betting.
So, how much did your mistakes cost? Did they cause you a serious psychological blow? What were your mistakes, did you learn from these mistakes and do you apply this knowledge in practice now? Were these mistakes simply painful, dramatic or catastrophic?
Not actually but a supposed to be profit. I have a lot of bets that option to cashout just because it offers already a good profit while my bet is already so close to win with potential x3 of my cashout profit.
The most disastrous to me that still I can’t forget is when the time I bet for Mbappe to win golden boot on world cup. Mbappe and Messi is close on score that time while France is already losing the game.
I option to cashout when Mbappe manage to tie the score with Messi until he made another score few minutes that seal his award.
