Well, the selfie thing may surprise you about casinos, but some fintechs ask you to take a video of you holding your ID card or passport with your mobile phone in order to sign up. If I remember correctly, some CEXs do too. So it seems to me that this is not going to be exceptional in the future. In the old days you went to the bank with your documents and the bank manager saw your face, or to the casino and they asked you for ID to enter, and something similar is going to happen online, adapted to this medium.
It's sad, isn't it?
Back in few years when we heard the word Crypto Casino, we used to get a picture that it was a casino where we can play anonymously. It's not the same anymore. Now in reality things are changing. All Crypto Casinos are moving out from the concept. They ask for KYC for silly reasons, even when it's obvious that VPN was used in some cases.
