It's rediculous loosing tone of bitcoin in gambling with single night it doesn't make any sense your just wasting your money instead of saving it to your future why not be contented on what you get? and just save it into your bank account just think of your family how if you gave them some of your money then you helped them with their financial problems.
and he didnt also used his money to make it as a site bankroll instead i think he can make alot of btc with that btc. even OP didnt decide to stop at 1k loss OP must have serious gambling problems he cant even self control.
With that serious problem, he must totally quit gambling as he is not making a good decision anymore. What gambling requires us to do is to have fun but we cannot really deny we sometimes do it for profit but with that we must ensure we are taking care of ourselves not to get addicted as it is an automatic defeat on us.
