So KYC is only harm and an extra trouble for any person.
This is how I think.
There are some gamblers who actually don't mind and they easily provide KYC to the casinos they use because they believe the personal data that has been provided will not be misused.
There are also gamblers who don't bother looking for casinos without KYC that are trusted and can be relied upon, so they choose the most popular casinos with KYC to make it easier and faster to use casinos without having to think about it and reset before using the casino.
Maybe you can come to such a conclusion because you yourself don't like KYC and mind if the casino knows personal data because you want to gamble anonymously in a crypto casino.
KYC is a problem for those who use multiple casino platforms, there are difficulties filling in all the data. While those using one platform or only a few, can e en be in favor of KYC service, since it guarantees a bit more security at least in fiat money sector. That's why, I think, in some time both KYC and non-KYC algorithms will be offered by most platforms at the same time, so that it will balance the demands in both groups of gamblers.
