This will always happen if you don't have a daily, weekly or monthly limit of what amount you should gamble with. If you have a limit and you haven't exceed the limit, then you have nothing to worry about even if you lose the first bet.
Believe me, it is difficult to control yourself when gambling. Even disciplined people sometimes break their own rules. When it comes to betting, anything can happen. Like a series of failures followed by a streak of luck. Our brain remembers it. Do you understand what I mean? That is, a situation when a person knows that he can win back what he has lost before. But this does not happen. Alas, this is how this direction is arranged and the admins are well aware of this. After all, all this was created by specialists in the field of psychiatry.
