This regulation might be problematic for some , for sure now the crypto gambling sites will receive a notice and let's see what would be the height of regulation.
Do you really think so?
Crypto sites are based in tax havens and operate on the basis of loopholes to say the least. They don't usually hold gambling licenses.
It is more likely that they get a notice for operating without the gambling license than for that regulation. However, if after so many years operating in the dark, they haven't received it, I don't see why they are going to receive it now.
I don't know why this has been overlooked for so many years. Maybe it's a mixture of not understanding and downplaying the importance of crypto casinos, but the moment they realize their importance they will force them to buy licenses or they will block them.
