Seriously, get used to this being forced almost everywhere you shop, and as an extension gamble. Governments are requiring more, and more in depth Know Your Customer (KYC) details than ever before, and its likely going to keep getting worse. I can understand it a little bit from some perspectives, but it is most definitely a breach of privacy in a lot of instances. The government wants it because they can likely detect fraud, and tax evasion more effectively, which you can't blame them for, and I can understand from that point of view. Unfortunately, its the people who abuse these services for the above mentioned crimes, that gets genuine customers to give up their privacy as a result.
All gambling websites are likely going to need KYC still almost every country in the next few years.
As i said many times before: AVOID CASINOS WHICH FORCE YOU TO KYC.
At least in crypto. With no exclusions, because this is principal moment: Cryptocurrency is grey technology, so you can be robbed with easy and you don't need to help potential criminals with any type of KYC
The thing is; this is going to get harder, and harder as time goes on. Its a law enforced by the government for the casinos to legally operate in much of the cases that its implemented, and as that law becomes more strict, and more countries adopt KYC the harder it'll be to actually avoid giving up your privacy.
