Though we can't blame the OP if he will push thru his luck, because that's his choice.
In my opinion, it depends on what your gut feel is saying about the outcome.
If you are not very confident about it, you can cash out and you will be happy about it.
But high probability that the OP already knew what his decision will be, just want to hear some confirmation from outside sources.
I agree with what you say, in fact we have also experienced the same situation as in the OP's story in this thread. It could be that OP just wants to know various responses from the community, or it could be that OP really needs advice from us as a community. The point is, every decision belongs to the OP as the account owner with the results of his winnings. and several times I read OP's posts, that he decided not to cash it. In fact, it is completely his. and in the end, OP updated that the game turned negative and ruined everything.
He also said he was a little disappointed and that is very normal in gambling. and what I appreciate about what OP said, is that he has no regrets. regardless of whether it is true or not, it is his right to speak. However, I really agree with what he said. In principle, gambling only has two outcomes. win or lose. continue or stop. and all that, is our choice as gamblers. If it's no longer convincing, I won't hesitate to withdraw it. but if I still want to continue, be prepared for various scenarios that will happen. in short, we would lose everything if we risked it all. or, get a win that is multiplied many times over. Most importantly, we must be able to bear all the risks. anyway, if luck is on our side. we ourselves feel it, get the results, plus get the results from the pleasure of risky types of entertainment.
