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.
The society is now turning into a digital society. This does not only happens on business transactions and any related activities but also to our current paper money which is seen to be replace into a digital currency in the future. It is not clear if bitcoin will be that currency or it will be another version of the fiat currency that will evolved into digital cash.
