hello @reeta0119,
this is one of the things i don't understand about governments, from what i see most states that implemented a digital version of their currency already had digital money for a long time, i don't understand why now they want to sell it as something new, the problem that coins solve is the transfer of value between people who don't have bank accounts, a good example is that if I want to send money to a friend in africa using the coins I only need a wallet and an email whereas if you want to do it through a bank we both need to have access to the global financial network, the problem is not whether the money is digital the problem is the controls that the state implements on the currency to control the citizen who is why the coins are superior to any version of them that a central bank implements.
