paper money have your days count
While I agree with you, it's not because of Bitcoin.
Digital fiat is the reason paper currency will go away, as I find digital fiat to be far more versatile and stable than any crypto. Bitcoin might be the best crypto, but all that makes it is the best version of the least dependable payment option
And what does that have to do with the price of tea in China?
More specifically, if you find "digital fiat to be far more versatile and stable" than any cryptocurrency out there, what does this comparison have to do with paper money? Should we thus conclude that digital fiat is more stable than its representation in the form of paper bills? In a sense, digital fiat can in fact be considered more stable since it is basically indestructible unless you blow up a central bank server room (provided there is any, in the first place), but this doesn't seem to be what you likely meant to say
