Apart from that, I think it's still the person's fault, but I say it was someone's careless mistake when they wanted to start the game, and not a mistake that was entirely due to the luck factor. in gambling. To be honest, I also feel what you feel, because I wasn't careful when I wanted to start the game, and I think everyone who is active in gambling will also feel the same way. It hurts quite a bit when they forget to change the amount of the bet in the game so that when luck is not on their side the game will only run for a while because the bet value is too big they forget to change, and for now when I want to gamble there are many things I pay attention to first, one of the most important is the nominal bet which sometimes changes itself to the initial setting.
Yes, it's someone's carelessness when he wants to play and doesn't check the bet before pressing the button. Yes, maybe many gamblers have had the same experience as him and I think that is a normal thing that we experience. And that makes us careful and always check the number of bets we want. And if we feel that the bet amount is too high or not what we want, we can still change it before pressing the button. But some gamblers get lucky because of their carelessness and I can only say that they were lucky because they managed to get that big win.
I also have a same experience, but luckily I double of my money because of my mistake, after that I stop to gamble and cash out my winning to enjoy my day. But most of the times I keep losing and that's has been expected because of house edge. Gambling for long surely will make your money lose and almost has no chance to make money, while bet in bigger amount has a chance to make money.
You are really lucky because you managed to double your money from your mistakes and very rarely gamblers could get their luck because of their mistakes too. The average gambler will only get lost because of his mistakes and will regret it because he has lost money that shouldn't have been lost at the gambling table. Gambling for a long time will stress you out, especially if you experience a losing streak. It can cause you to want to use more money to recover your losses. But it's also not easy to get.
