There are many games on blockchain on Asian market. How benefecial is it? Therefore, gambling industry has never suffered from lack of attention. And now, when blockchain technologies are being used for online games, the demand should increase. At least among users, such platforms will cause more confidence than ordinary platforms that spread like mushrooms, where you do not know whether you can withdraw your earnings or not
In terms of economic growth I wouldn't say that it is beneficial.
However, it is an industry that it is reformed by the blockchain technology and it has a lot of gains since its initial start. We actually don't get any value from those casinos. They are just beneficial for bringing mass adoption.
That is true, gambling add nothing to the gdp of any country because it is like recycling of funds within the economy. Economic growth is as the result of products and services why gamble and casino add not to productions and services. For those that are into gambling business I think blockchain do help them and that is why we are seeing many gambling business adotpting blockchain technology.
