That's the problem with garbage token that have no purpose. Unless you have an exchange option on site, like on fury and BC, it's almost impossible to buy and sell this nonsense. Look the blackjack.fun and their ridiculously bad token project. So hard to actually sell this stuff, and if you get it out you can only send it to some exchange that nobody ever heard of. These sites just want to make a quick buck with those tokens.
It is curious that you do not mention the token of the site you promote in these examples. Haven't they launched $MWIN or something? Otherwise I agree with what you say, the best is to have an exchange option on the site, but I was struck by the fact that you did not include the MetaWin token in those mentioned.
