If you have a look at the scam accusation section, you will find that no casino has a good reputation there. Each and every casino which has their ANN thread here, has at least one complaint against them; sometimes confiscated funds, delayed withdrawal, not paying the winning, freezing account etc. Why this is the principal of all the casinos? Why they can't operate without having any issues? They always do this shit; who knows what has been done with people who don't know how to deal with such a casino. Can you show me a thread that never had any reputation issues on this forum?
Imho every post praising a casino/business and every post calling a business to be scam, all have to be taken with a grain of salt.
Various crypto casinos did/do offer faucet or various bonuses. Some tend to abuse that money. Some use multi-accounts or other tricks attempting to cheat. When caught they call the casino scammer.
Sometimes bugs happen in casino software, leading to friction and, again, calls for scam.
And sometimes the casinos do try to scam.
A special mention is the KYC rules, some users hide behind VPN trying to avoid the rules, some casinos hide behind KYC rules trying to milk some easy money.
As I said, both parts have to be taken with a pinch of salt. Nobody is perfect, but also there are some good casinos too around here.
