This usually happens to many people if they are following up on their game. Unless I place a bet on a live match, I don't usually go and revisit that slip until I know that the game has completely ended.
If you have that confidence with the way you do your research, it's better to leave things that way, just wait for the outcome to removed stress when something happening while the game still in-play.
Although there are times where I place bets on particular matches, I might be watching the match on the game house. This is how the game might be playing, which might start giving me a second lesson on whether I should allow it to play or if I should go cash out the bet.
It happened most of the time when watching the game and fear comes up, either you don't want lose everything or you are already satisfied with the amount that you already got,.
There are times where we might take the decision of cashing out our ongoing game, and it will be the best decision we will make because the game might play against how we predict it, so cashing out gives us room to have a little profit instead of losing it all as a result of overconfidence in the game.
Sometimes yes if the decision you make favors your bet, but if not and you cashout immidiately instead of waiting for the final outcome and the bet happens to win, that's a big regret for sure.
