There's nothing happening with gambling projects if crypto will be regulated. Im sure that the regulation will be putting its focus into the taxation for crypto users and AML. The gambling platform just need to follow what will be did by regulators. It's quite easy to follow the regulation.
I think this will not become a serious problem for the platforms that are also supporting the crypto.
Yes, regulation is not a problem at all, crypto just helped more in payment. Making payment, both deposit and withdraw faster which is one of the reasons o prefer to use crypto for gambling.
But on the other hand, some people are gambling from where gambling is not legal, such people may want to bet using foreign sites like those on this forum, but i won't advice such because it is already stated on most of the gambling sites ToS that people from some named countries and places are not allowed to gamble on their site.
There is not problem regulation pose, it is for AML and some other good reasons.
