The main reason why cryptocurrencies had become so popular it is just because of its anonymous aspect on which you can really be able to be cheated any moment. Even if you still believe in "anonymous aspect".
There are some gamblers who really want to be anonymous, they choose casino without KYC, but the main part of gamblers, who tell us about anonymity share their private data with any service without any doubts. Be honest with yourself, analyze how much services have your data and add one more - your favorite casino.
It is very true what you say, only sometimes the same system is in charge of forcing people to give their data whether or not, I think that in the world there should come a simpler way of not Fighting against the system, where they allow freedom to remain anonymous, with more privacy, but it is very Difficult, in fact I know that through social networks the Information is channeled to know who is who and what things the person thinks , and what position they can occupy in treatment with cryptocurrencies, governments have detection systems with AI and who knows with what other technology where to be anonymous, it would be necessary to delete oneself from Ssocial networks and that is something that currently for many it is impossible to do.
