As we can see the cryptocurrencies are still being established in the knowledge, socialization and full utilization of humanity, could the cryptocurrencies cause the use of physical money to be eliminated, is this possible?
For my own opinion, Physical money can't replaced. The number one reason for this is, how about the people who don't have phones, internet, bank accounts, ledgers, trezor and many more. They can't buy things for their everyday life and and also us, we need physical money in our life.
