Here is the issue.. I have a decent grasp on understanding concepts & things work normally but i really stuck here..

There is a heap of ICO's coming out , part of the business model is potential customers need to go buy there coin from an exchange to use on the said app or website..

Now i have been involved with a few non blockchain business & have a Degree in business.. One of the major points we are taught in business is that to be successful, you must never have a situation where a potential customer has to navigate away from you're business , app , website.

The second that potential customer leaves you're business, there is a bloody good chance you have lost him/her for ever. 

So why the heck are these ICO's setting up to fail buy telling customers you can buy tokens from an Exchange ? seriously who can F&%ked doing that these day's just use some hyped up app or website ?

Is there no better way ?

Why don't they have coins restricted to there app or website where customers use & is not tradable on exchanges, then have a separate coin that they pay stacking per year ( dividends ) in for investors or they could just pay from what ever profit they make..

Maybe there is a better way then i'm not thinking of , but there has to be a better way to doing business the current method  ?
