Sure, and if that happens then it's value as a liquid fiat will decrease. The idea that "it only goes up and to the moon!" is what has made everyone declare it a scam.
If it currently has a use case then it has value. The currency is not a "scam" but this horrendous idea of treating it as an "investment" is delusional.
I think cryptocurrency has a few very valid use cases, but I think it's been shoved onto everything when it's not even needed (CSGO has been fine without NFTs).
