...Situations like these, we tend to take it for granted until all hope is lost and we suffered the consequences. That is also why double-checking everything is the key towards preventing mistakes that would be very costly in the long-run.
I have had this situation several times. You simply double automatically and it is very easy to press the wrong button by mistake. And you will find out that your balance is empty only when you cant make another bet. In any case, you do not need to keep large amounts on the balance sheet.
mistakes like this often occur, the main cause is the lack of focus when betting or using the Martingale strategy when losing in a row, so being able to make the wrong decision to be able to double the bet without looking at the remaining balance. but the incident that happened to the op seems to be in a hurry to place a bet manually so he doesn't pay attention to adding 0 and causing a big loss
