That's a lot of money spent on gambling and I'm even more amazed that you are only doing it for fun

I don't know if you have that "never give up" mentality but I don't think that really works on gambling.
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.
Seriously, you can limit it to 50% instead of throwing 90% of your mined btc.
