There is more than enough space in the sky for every bird to freely fly, so, yeah, this is your opinion about stake, which I believe is based on your personal experience using the casino, I personally, I respect your opinion, but I doubt if the general public or a large audience will do the same.
And this is because Stake is actually one of the biggest online casinos with lots of users, and also one of the most reputable, and then being a casino from an English speaking country, there is no way you except them to accept a kyc document that is not written in English(language they can understand), I am also from third world country and I had no issue of any kind passing my kyc verification on stake.
Stake definitely has its fair share of issues just like any other crypto gambling site out there, but it isn't the worst by any means. It's actually one of the best ones out there when it comes to the casino games.
However, its sportsbook section downright sucks and needs a lot of improvement(Better odds, Smooth live betting UI etc). No comment on the KYC stuff since they didn't ask me for any documents yet.
