My last withdrawal from Stake was two and a half months ago. I have made 6 deposits after that and lost all of them. Also, I have been losing my bonuses since then without being able to turn it into the desired amount. My luck has disappeared from Stake.
Take a break, testing on different casino, test on different gameplay and hopefully you got one days streak. If you have the streak, just keep push it until is getting lose. Damn, I once not getting any withdraw for more than 2-3 month as well. It's pitty too, stressfull and want to self-exclusion. I now, is also on streak lose as well, can't even passed at least 1,000$ with deposit 500-800$.
