My worst decision was playing in bustabit.com site and then playing in dice game and losing most of the coins, after that i found one of the script in bustabit and recovered the lost bitcoin, and now only doing sports betting as i have some knowledge about cricket and by following my instinct i have made a good profit.
I think gambling is most often made someone cry of course because they are the wrong choice. thus making them big losers are poor or even to lose all their money. I never played bustabit and I busted a couple of times. but it was not the worst decision. because I always control my game so I have limited balance in the wallet to gamble. so it does not make me a big loss
