In my experience, sometimes it's worth to take risk without thinking. But it's because I have an idea of what I am doing and just let it be whether my bet wins or lose, it won't even a huge problem for me. I think with the others that does this, they're putting all that they have and so if they lose, they're regretting it forever. And that is the reason if we're going to gamble, we have to make sure as well that it won't be problematic to us if we lose. But if we hit some wins and the gains are that much, we don't have to put them back at risk again. Because the typical situation happens is that it goes back to the casino and they're win over from the lucky bettors if they're not securing the profits.
If someone once risks to play everything he has, it will be the biggest mistake and it does not matter whether it will be a win or a loss. Because if a player has decided to do this once, he will want to do it again, and if you repeat it, it is not difficult to understand that losing everything will be a matter of time. It is better to bet only what you can afford to lose, even if the winnings are small, it is still better than losing everything in one bet and being left with nothing.
It depends on the gambler. There are gamblers that if they do an all in once, it's most likely that they are already fearless and likely to do that again. The risk that's taken once can easily be taken again for the second time around but it won't change the fact that the results are always varying whether you've done it before or not. And I agree that we should always gamble with an amount that we won't regret to lose.
