I have some simple questions about PoI.

(1) How the share of profit will be paid to the ERM coin holder?
1.1. How many times of profit sharing per year?
1.2. Dividends In what currency? ERM, BTC or USD?
1.3. How to pay the dividends to the ERM coin holder (i.e., the payment method)

(2) After one has spent his/her coins for many times, how your team could trace how much ERM this guy has? According to Bitcoin protocol, it is impossible/very difficult to trace how many coins a coin holder has.
P.S. Dividends should be given to coin holders, not IPO investors. If IPO investors are keeping their coins, they are still valid coin holders.
