If anonymity is needed, the administration of casinos and other crypto sites will come up with ways to ensure anonymity for their customers. One of these ways is to create casinos in jurisdictions that are loyal to cryptocurrencies or not register casinos at all.
The cryptocurrency was created for anonymity. But now no one remembers about it.
States increasingly want to regulate and control cryptocurrencies. Therefore, anonymity is becoming more and more valuable as there is less and less of it.
