Well your mistake is common to all gamblers that is why gamblers end up broke because of chasing their losses instead of calming down and rest for a while. I made that mistake too long time ago and good thing I only used little amount of bitcoin since I can't afford to lose a lot of money through gambling. I would go crazy if I lose 1btc bro.
That is the most reason why most of the people are addicted to gambling, because they wanted to win all back their loses that bad. In my opinion I'd try another way rather than to be contented on to something that is not benefiting me at all(and that is gambling). I've been through this before also, but that doesn't make any sense, I'm still losing money everytime I tried to win it all back, so I've decided to do something else, and that is joining Signature Campaign.
