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.
If it is too difficult of us to trace the Coin holders Coin we can always take the steps of manual verification for precise calculation of coin share for ea holder. Otherwise we will verify them thru final balance of coin on ea addresses ^^, but am sure Tech team will come up for a solution for this.
manual verification
Not possible if your altcoin becomes successful
Otherwise we will verify them thru final balance of coin on ea addresses
Seem like you are proposing some promises, but do not have a correct concept about "address" for bitcoin-based cryptocurrencies.
Your tech team better providing a solution here before doing the IPO.
Good luck.
Actually it will be possible to create an automated system which will simply share to every adresses on the blockchain once it grows big enough excluding the specific exchangers adresses.
For now this is not a concern.
