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.
maybe in short time there will be as adjustments and some panic from investors and players will take part but this is a basic problem that eventually will be provided answers and solutions.
But look at it now, even there are strict regulation in some part of the world, gamblers and investors still finds place and ways to continue their dealing in crypto world so indeed that this will not totally affect the whole system.
