Yes, I agree with your answer all above. If a country prints more money than usual, it will not make the country prosper or advance. But that would be a big problem for the country.
Yes because it will go all wasted making more money than needs get the economy of country badly way, I think the main reason behind it is increasing use of crypto currency, now people use digital currency more than paper money so gradually the need of money is getting smaller and the need of digital currency is increasing so one day country will completely stop printing money they will use digital only.
