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
Actually it should be considered as a mistake because it leaves bad effects on your life so its better to leave it as quick as you can. Learning is a good habit in your life but one should not develop the habit of learning things that are not acceptable in the society and if he will try to do so, the people around him will discontinue their relation with him. Being addict is a mistake but losing money all the time is not a mistake because it depends upon your luck whether you lose or win.
