Is it not better that the fear of losing money cautions you to gamble responsibly than having confidence in your bet and using what you can't afford to lose? it is easy to talk about the what if i have used a big money, considering that he won in this case, have you considered what would have been your opinion in this case had it been he lost?

We have been using this phrase that scared money don't make money, but if you allow yourself to get too exposed to using too huge amount anytime you gamble, the same you will run back to lament after losing the money. Gambling is a game of risk, and we are all aware of it. if you have the mind of going into it with something that will at least yield good returns, then there is nothing wrong doing it that way but if that same amount that can yield you god returns is something you will not be willing to lose, it is better to regret not using much because you have won than using much and then lose at the end. Small bets always come out as predicted more than a bet where you use a big amount, maybe there is something about this.
