Question about price levels/inflation and cryptocurrency’s value

Hey folks, i just wanted to get some insight about how deflationary currencys with PoS model work in our economy.

So fiat currency is inherently inflationary, we print and print and devalue our currency which forces price levels to go up right.

If we constantly force price levels up, and if cryptocurrency hits a plateu in value, wouldn’t crypo be experiencing the side effects of inflation still?

Say “x” crypto is worth 100$ and its proved to be the stable price for it. And milk goes from 4$ a bag to 7$ a bag over “y”time, our crypto is worth less tommorow than it is today as long as feds keep printing money and causing price levels to rise, right?

Im just trying to understand this from a economics perspective; would love to hear everyones insight!
