What are some the more idiotic and stupid mistakes that you know you shouldn't have made but did anyway. Yes this includes other none gambling stuff like sending btc to the wrong address. I'm interested to find out the stupid things other people do. 
Well, I have a lot of mistake have done in playing gambling like I lose a lot of money upon there. I remember that I win that big and despite of what I have earn I still continue then I lose all of that instantly. But the most mistake I have ever made is that when I enter this gambling.When you get into gambling site, it is not a mistake but it is learning something new. When you are addicted and keep losing money, that is a mistake. Making mistake is one part of learning but if you keep on dong the same mistake over and over again, that means you are not learning at all but you intentionally want to play and hope to win
Indeed it wasn't a mistake , but inside of the game you will feel have made a lot of mistake as mostly you have got lost instead won it.
The worst one is when you know you ae in huge debt position but then keep trying looking for the luck to cover it up but then you get nothing just morr losses coming.
