The main purpose of making coins is to get a profit. I very rarely meet projects that have a real product useful for community. Most of the coins are created for speculation and in order to make the project team rich.
I agree with you, if we take a closer look at these ICOs for instance they are existing mostly for profit, they do not offer anything outstanding that they will require their own token. I guess all of them should do something like KU shares and similar tokens to give bonuses to investors. Other than that to have real use on their platform is not what they should go for. Because who on earth will keep up which coin to buy to use certain service? I'd tell you,nobody.
