It seems to me that gambling will be popular at any time. So it was a thousand years ago, and so it will be in a thousand years. This is a very promising direction!
And even more promising direction is not to gamble but to invest in a platform for gambling.
I think that investing in gambling can make quite some serious money. This is a very profitable business.
Well, when the platform is popular, and you bring your game there and it starts working there as much as you are exhausted, much still depends on the paying people.
