thanks for your reply

to clarify, when you say

{"mapping has been done to ensure we will have a total number of coins"}

do you mean that the five million maximum will NOT CHANGE? or are you saying that the max cap will change?

please explain what you mean

I suggest that the max cap NOT CHANGE - after a cap is reached, I think the mining (whether it is POW  or POS or POW/POS hybrid) should be sustained by transaction fees and other fees but never by changing the cap AFTER a specified maximum cap was stated.

It is OK to have an unlimited supply coin as long as that was the stated policy from the start

But if the initial policy was a maximum cap of a specific amount, then it should remain fixed at that exact specific amount - the software can change but the max cap should never change after it has been advertised - - - just think about the mess if bitcoin decided "now we change software and the maximum bitcoins to be issued is 100 million" that would destroy the very idea of value by fixed deterministic mathematically bounded supply...
