personally it is very convenient for me to send money to my friends in other countries! they get them very quickly and the commission is cheap! That's all it says! Bitcoin is a new digital money. We all still live in the digital age ?!))) bitcoin is rapidly moving and developing the entire world economy! Paper money gradually goes to the background, after bitcoin.
Off course comparing the two, Bitcoin is better than banknotes, since bitcoin itself are having a faster transactions in terms of money exchange with very low fees, while banknotes is a type of negotiable promissory note and considered legal tender along with coins. They make up the bearer forms of all modern money.
