I don't think it would last long or we can expect that the demand would really grow.

They are using bitcoin to avoid government restrictions, and I think government will know that and if they order gambling using crypto will be illegal, I guess the adoption that we are expecting might not happen, also, even if the a country is pro crypto, it doesn't mean most transactions are done in gambling and since crypto is regulated in their country, I presume, so I guess it will be easy for them to track individual's transaction as people will use an exchange to convert their fiat into bitcoin and vice versa.
