From what I have read, this is a closed system, inside of which coins managers. And what will it be like - conventional individual signs, and all different? That is, they will not be tokens of the ether. And how to control their number is unclear.

Also in chapter 6.3 Managers' Coins you write:

"The investor can withdraw the invested money, but only at the end of the reporting period."

and ibid:

"Instead, the user buys "tangible" coins that are displayed in his or her personal cabinet and can be cashed at any time."

I understand that we mean the withdrawal from the system of fiat money in both cases, well, or btc, eth. So explain why there is a contradiction? How can an investor dispose of his funds with respect to withdrawals from your system?
