I don't think the new casino will ever be able to become a legit casino because we don't know how their future journey will be. Like it or not, KYC will probably be implemented in crypto casinos so if we use big money to bet, we have to be ready with KYC so there won't be any problems later. But maybe Freebitco.in can satisfy you because until now, the site does not ask its members for KYC, and I think many gamblers use big money to bet there.
I also think that, like you, the time will come for all casinos in their entirety when KYC is mandatory, in fact I think we are already experiencing that, and that is why there is so much resistance that is currently taking place, there are many threads of discussion of this, and yes, I cannot deny that those who are against KYC are absolutely right, but on the other hand there are regulations and licenses that require a casino to be authentic and that can make a difference, because if a casino it loses its authenticity and its licenses will not be seen very well either, so I see KYC as a double-edged sword.
You will have a hard time finding a casino that requires no KYC for you to play. Most of the casinos now require verification of their client's identity because of the regulation imposed by the government due to unusual activities that are rampant nowadays. Hence, you'll really have to abide to their protocols to successfully create and account and enjoy the features of the casino site.
While there are also casinos that do not require KYC, but they are now very few because KYC has becoming more of a requirement already. You can still find some, but the casino features are limited and the games you'll be able to play won't be much in variety too. If you are specifically looking for high roller like what's written, I suppose you'll have a hard time too because most of them are requiring KYC, if not in the very beginning of the process of making an account, it will be the moment you decide to withdraw your winnings. Be careful for those who claim that they have what you're looking for. Always do a background check to make sure.
I would rather think of finding a way to go to a safe and reliable casino, I think that as time goes by, people will realize that the fight between fighting for No KYC and going in favor was no longer easy of KYC, because it is very difficult, the machinery that requires a KYC is practically worldwide, if a casino does not have licenses, it is not authentic, it is not reliable, therefore there are examples of authentic casinos that make a difference, in my In this case, I did not mind giving KYC for stake.com, bitcasino.io, duelbits, Sportsbet.io, all these things are what really make a person leave their data in casinos that would never dare to let information leak.
