All these stress for what? Because you want to gamble online? I don't really get the reason for KYC in online crypto casinos, crypto it's is a decentralized currency, so what's the essence of KYC when you're using a decentralized currency on the casino, if it's a normal online casino that doesn't require the use of crypto, then it's cool, but it just don't make any sense making KYC mandatory before you can bet on crypto casinos.
This is the reason gamblers as slowly moving aware from online crypto casinos that requires KYC and very soon I bet we won't be seeing more of them and they'll be forced to change that policy.
Who told you that cryptocurrencies are decentralized? Only Bitcoin and a few others are decentralized while BTC is the only one that is entirely decentralized today. Not having any kind of information about the creator of Bitcoin and their identity makes Bitcoin the one and only true decentralized cryptocurrency. And yeah, to you, it may seem a lot of stress, but those crypto casinos have to face lots of issues. This is the reason they say that it is mandatory for people to verify KYC before they can do anything.
Doesn't matter if you are using a decentralized or centralized crypto for deposit, when you are using a centralized platform, your privacy is already compromised. And day by day they are not going to remove the KYC verification, but rather those other platforms that haven't implemented this yet, they will do it in a matter of time. If you want to bet, you need to follow their rules.
It is important for a company to do such a thing. Maybe you should do a bit more research on this.
