You can also get paid for securing the cryptoasset system in a PoS system although I don't think that has an equivalent in the fiat space.
Some inflation is fine (some would argue has some value/purpose) - what you don't want is too much inflation, or deflation ("hyper"). But I doubt any cryptocurrencies can truly solve it (Bitcoin least of all).
But what I find fascinating, especially from the Bitcoin crowd, is how they trash all fiat currencies ("because inflation!!"), but still use fiat to compare/set the price of Bitcoin.
Basically, without fiat to give it value, their precious Bitcoin is worthless.
If you did not have inflation - or had deflation even, like in the case of bitcoin - everything would "become cheaper", but it would make certain types of goods/services scarcer (since they'd be paid less and less for doing the same labour due to the deflation, and so would choose to stop doing it at some point).
He changed his whole life by moving away from Turkey to the country with the reserve currency status and then says that ,,everything's fine with the money and banking system''. I challenge him to move back to Turkey and interview some people there.
