OP, let me first of all say that I am sorry for your losses. Sadly you clearly have a severe gambling addiction, the sums of money youve been playing with are no joke. It saddens me to read that somebody could get so deep & obsessed with gambling. What Id suggest is you find help & Im being serious, you need to stop gambling all together. There are organisations for gamblers that can help you. You need to stop gambling altogether before it ruins you mentally & financially.
I do have to comment and say that gambling should be fun, it should be a hobby. You cant blame a casino or sports-book for your losses. There is no guarantee to win, you gave to accept that. Its the way it goes a lot unfortunately, you never see a poor casino. There is usually only one winner & its not us, the punters.
Bitcasino are provably fair so theres nothing you can do. You just have to stop gambling now, before it fucking ruins you. Get help, seriously. All forms of addiction are crippling but you can do it, I promise.
Good luck my friend.

Thanks for the advice. I don't want to sound like an asshole but I am playing for fun and obviously trying to hit a jackpot just to win some of the losses back. I have a large mining farm and I'm generating a good amount of btc per week. But 90% of it gets dumped into bitcasino because I feel that my luck should change every week haha. It never does. Every deposit is lost. That doesn't sound provably fair. 200+ deposits all gone. They should pay something if their slots are set to 90+% RTP.
