I think a lot of these Alt coin developers are hiring developers to create popup gambling sites like this to create a use case for their tokens.  Yes, a Weed coin is a cool concept and I think a lot of people will find this entertaining and fun... but will it be enough to grow past that stage?

The success of these Alt coins are in the utility of the coin... not only having the ability to gamble with it, but to actually buy something with it. There are some many variations of Crash and Dice and Plinko games.... so you must have something unique to draw in the people who love those games.
