it really happens to some people who gamble, generally this happens to those who gamble with the aim of getting profit until when the results obtained are not in accordance with what they think their emotions are provoked and make them want to turn things around by continuing to gamble again and again even though they have lost repeatedly. And usually people like this are not easy to withdraw the winnings they have obtained because there is a desire to get a bigger win that can make them not do the withdrawal option. Even though the good option when you have won is to withdraw it because winning in gambling is not certain so extending the gambling session will not guarantee that you can win again but it is possible that the winnings that have been obtained can be lost again.

And consider to take small earnings if we are unsure with the possible outcome of the reamining games, most of the time if not all, you'll regret your decision especially when your original pick wins, as the amount of potential earnings is really huge compared to what you decide to cashout, though same thing if you lose as you push your luck it's also tough as you regret losing your money before the outcome you missed the chance of winning and the chance of saving your money.

Of course a person bets based on his own analysis and predictions but a lot of exceptions can happen in a game and no one can ever guarantee that.  So if you are offered a good odds before the end of the match why not cash it out? When you wait for the whole match to finish because then you will get some more amount return then it is definitely called greed.  In many matches it has happened that a losing team has won in less than 1 minute. Then you lose the bet.  And then of course you blame yourself for not cashing out that time. our emotions and greed can never satisfy us in the slightest loss

Yes, it is a gambling game with features added by the casino to minimize user loss but it could always serve as a trap for the user because the chance of winning the end fund will reduce based on the percent set by the game provider.
The Op used the word beneficial because it could safe the gamblers from losing all the fund. S/he used the word trap because the disadvantage of it is taking the gambler chance of winning big.

In my opinion, this is not a strategy but more of an option that users must be able to utilize to minimize their own losses, and indeed we can minimize losses in gambling but it depends on what we are like in gambling if the gambling that is done is to pursue victory then the option to cash out will usually be set aside because it prioritizes the victory that must be pursued. And withdrawing money when in the middle of a winning streak can be done but as I said it depends on ourselves.

Cashing out or withdrawing the profits that have been obtained is one of the options that must be utilized, I always prioritize this as much as possible even though sometimes I ignore it but that doesn't make me keep doing it.
