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?
Technically the proceeds from the ICO should go directly into the implementation of the project, whereas the team's share (20% or whatever) can have a different purpose, perhaps as an incentive to make sure the project succeeds. There are other token allocations being used as well - for bounties etc.
It's all quite pointless though unless some ironclad escrow is in place for those funds. As you've correctly noted the team controls everything anyway.
