Maybe the devs and the teams would think that if their tokens related to gambling, it is better that they created a gambling website, attract the investor to their site while the investor can play gambling and make an investment in the same time. It would be better for the teams so they can get double profit from the project. Maybe it's like a new trend among the dev, and I think we will see many more like them that will launch in this month or next month.
The main reason why a token built is to have a specific use . so if a token is a gambling based token , its normal for the devs of those token to create a gambling site . but i dont see that this kind of idea are getting trendy or indemand . i still see alot of popular casino and gambling sites that only accept btc , eth , bch and other top cryptos .
