It is difficult to think that money as we see it today will totally disappear, many banks have a large amount of these, so it is not in their best interest for this to happen.
Digital currencies still need more time and a lot of support, people who have this type of currencies must be patient and 100%, because I am patient.
The purchasing power of currencies if it could be increased, has always been used, since memorable times.
Greetings and enjoy your coffee
