Bro, it's not possible dealing without paper money, it's the bedrock of any monetary policy in any nation that's why some sectors doesn't accept digital means of payment in their business, there's a reason why. Everything must not go digital even if people is saying digitalization is civilisation bla bla.
I bet you, there are business associates that wouldn't support the Digital Euro for their daily transactions which are the drugs dealers or other illegal business dealers. And I'm pretty much sure that any payment app designed for payment will have a certain restrictions on the amount of transaction to be done daily.
Europe and other part of the world is not Africa where the world seems to be darker in terms of technology. Businesses has advanced and technology is the order of the day. Come to think of it which big business tycoon moves about with paper money this days when they go for their business trips? Even a petty business trader takes caution by not going on a business trip with paper money to avoid been rubbed on the road
Electronic cash is more popular than paper money globally. Digital payment methods, including credit/debit cards, mobile wallets (like Apple Pay and Google Pay), and cryptocurrencies, have become the preferred choice for transactions due to their convenience, security, and speed. Many countries are seeing a decline in cash usage, with some even moving toward cashless economies. However, paper money is still widely used in certain regions, especially in areas with limited banking infrastructure or where people prefer cash for privacy reasons.
That is the response I got from chatgpt. Digital payment will become the order of the day because of its convince and accessibility. It will have wider adoption and depending on the model chosen by the central bank they might choose to eliminate third party intermediates which gives their citizens direct power to ECB.
