Now its shockingly clear.
I thought when a team decides to have 20% of the tokens sale, i thought they dont have any control over the other 80% of tokens, neither its equalivent amount..
But as you said, the team has the full control over the tokens, at least while the ICO.
Thats why the ico fraud % is extremely high

That leads me to another question:
Why the team devides the tokens into %, like: 20% for the team.. 80% for investors? Is it like the team memebers will be awarded this agreed tokens and will hold, like shares in the company?
