Not necessarily but also keep in mind that not everywhere in the world do people have internet!!, also some people in this world will NEVER be able to afford internet, making crypto useless to them!!!
every country has advantages and disadvantages, there are countries that have very high internet networks such as developed countries so they can already use bitcoin in each of their transactions, but there are still countries that do not have adequate internet connections, so that citizens cannot using digital currency, and of course banknotes are still very much needed, digital currencies or bitcoin will have different users than fiat currencies.
