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. 
The worst thing I made in my life regarding gambling is that i spend so much time in gambling. Because of that tailored problem occured. I have no time for those important things to do. For example, I forgot to create a post. Since that is the thing that happened, i have to work all day then I get tired. Plus i got my money in gambling. So i have to work more harder to get back my losses in a sure way like signature campaigns. Now that I have learned my lesson, i will not repeat the same mistake again.
