First of all, the site will be of interest to those who have already played gambling in the first year, but I'm not sure that there are investors among them.
investors are interested in making a profit from their investments. And gambling always brings profit to its developers. So I'm sure investors can be among the players.
Gambling is not an investment, investors are interested in things that are likely to make them earn money like buying tokens during ICO and sell it later on exchange with high price, or host game, but not playing ( Gambling ).
For me gambling is just a form of entertainment which shouldnt be considered as an investment of a job because it should only be played to spend some of your freetime.
