When i join this crazy crypto world in 2014 i did it because the casinos used to give away money to the customers, the old and famous chat lotto was a thing. And for that time the licenses for the casinos was irrelevant, all the users used to make the same question:

Is this provably fair? and how can I verify my rolls?

Now is totally different, we see more users but none of them cares if the site is provably fair. they just focus on the license. So, we can see new casinos but at the same time we see new gamblers too.
