I don't like the logic your using at the start of the post - it gives it a very sour taste. Using game history isn't really proof of anything, bitstarz does appear to be provably fair, and whilst I haven't talked about their deposits/withdraws yet, that side of them seems to be fine. Losing a lot at any casino, whether it's bitstarz, bitsler, primedice, or even vegas casinos doesn't mean the casino is rigged, you could just be having shit luck.
I don't like their harsh stance on confiscating deposits, but if they've stated it in their terms and everything - they are free to do so if a user's KYC is fake, or inaccurate, but they can't go out of there way to make sure KYC is faked, that's the corrupt part.
Yeah so why KYC people that deposit bitcoins and play live real human casino? Bitcoin users 90% are anonymouse and they don't feel as providing their ID or some sort of identity and also asking for KYC after withdrawing is straight up rip off.
