Cash is a kind of paper currency that has existed around us for a long time. It is a sign of the strength of the economy of a country. Moreover, cash has better characteristics than cryptocurrencies like: popular with all people. , fast, can be used anywhere, in any case, many ATMs have cash support while there are very few ATMs that support cryptocurrencies.
Cash is not a kind of paper currency.
There are no more kinds of paper currencies, that is the definition of cash.
And how is it a sign of the strength of a certain country?
Both Zimbabwe and Japan, Somalia and Germany have cash, are all four of them strong economies?
Again, why do you think cash is popular with all people? I don't like cash.
Sweden does not like cash except for 2% of all transactions.
Furthermore , another stupid thing "many ATMs have cash support".
No way, I would have not believe that, maybe is because that's what ATMs do?
