It's incredibly reductive and almost embarrassing to say "it's simple math".
Nothing about economies is simple.

Inflation is an INVESTMENT.

On the Bitcoin network the only investment being made is for block security... which means they can't scale up in any other way but highly secure small blocks. Cryptocurrencies that are hyperinflating can have massive success if that money is actually going to places that generate more value than they cost. This is the definition of an investment. Inflation is only bad when a corrupt elite controls it for their own ends (aka the investment is a bad one). This is a nuance that almost no one seems to understand... and even worse everyone acts like they understand the situation perfectly because it's "so simple".
