Good to see people are still wagering as much as possible. Happy April Fools everybody and do not submit KYC
How long have you been investing in the site? Generally investing in the bankroll is never a get rich type of deal, you need to leave your funds there for a long time and you will always come out ahead.
Basically you can't really lose because the casino always wins in the long run however there are weeks/months where the profits can be against you for a little while, you just need to wait it out. Since BTC is still very low there isn't much you can do with it. Even lending it out for margin on sites like Bitfinex doesn't result in much profit.
I am a very new user to be honest. I have tried investing on only 3 sites. The first one I withdrew early because it was losing badly 2 years ago and after I lost money the whole bankroll just got closed down. Then I left all casino bankrolls until February this year. I kept some in Bitvest and some here on YoloDice. Basically, it is just my Bitcoin earnings. No matter how small I try to save them. The only problem for me is I keep divesting to gamble hehe.
You CAN lose, do not be fooled. Even if the edge is in your favor. Bad luck happens:)
