It has been said that the creation of new ETH will be discontinued with Caspar and PoS. Is there a fundamental reason why this is necessary, rooted in the protocol or is this a deliberate decision by the Ethereum Foundation?
After PoS switch at about the 90 Million total issuance mark, Vitalik expects an inflation of a fixed 0-2MM per year. The details are being ironed out with Vlad still. That is less than 2% per year and a disinflationary currency as it is relative to total supply.
