What threatens the economy with an unlimited number of coins?

Question

Fintech

Most cryptocurrencies have a limited number of coins. However, there are cryptocurrencies where the number of coins is limited. For example Peercoin. Here's what Wikipedia says : "Peercoin does not have a hard limit on the number of possible coins, but is designed to eventually attain an annual inflation rate of 1 percent. This feature, along with increased energy efficiency, aims to allow for greater long- term scaleability."
Explain what are the advantages and disadvantages of cryptocurrencies with an unlimited number of coins? As well as what prospects can have currencies with mortgaged inflation compared to currencies without mortgaged inflation.

Answer 1

Why deprive people of their money? Even 1% is theft.

Answer 2

The economy is nothing. There will just be inflation of a particular cryptocurrency.

Answer 3

On Habré, it seems there was an article about money getting cheaper in one German republic. And as a result of this, instead of accumulating money, people constantly put it into circulation, which led to an economic boom. I would be glad if someone gives a link
