In an article featured on corepay.net titled 'Cashless Societies: Which Countries Are Making The Switch?', it highlights the global trend towards cashless economies. Many nations are embracing digital payment systems, with Sweden leading the way, although it has not yet achieved complete cashlessness.
This will resolve "Yes" if any country implements a ban on cash or physical currency by 2030 to transition towards a cashless society.
@jesyspa a repeal of the legal tender laws is very different from a ban on the currency. Legal tender just means debtors are required to accept it as payment for debts. Gold coin is not legal tender, but not banned either.
"ban" is kind of a sliding scale rather than a binary. Civil Asset forfeiture in some parts of the US means essentially that if you have any significant amount of cash the cops consider that by itself suspicious enough to take the money from you and then you have to prove your innocence to get the money back. That's almost a de facto ban on large amounts of cash. Or if a government requires you to record cash transactions larger than 1k on some digital database that's almost a de facto ban on large amounts of cash -- the cash is superfluous if you have to use a digital ledger for everything anyway.
