To have money in a bank account, we still need cash, but every country's cash is printable and it is not limited. This is the problem. The unrestrained nature of cash will inevitably lead to inflation, which no one wishes.
Electronic money is considered as gold or diamond. To get it we have to "exploit" using complex algorithms. The more participants, the harder it is to exploit and it is limited, so its value will increase. => The inflation problem will be solved. I think the future of paper money will no longer prevail, and electronic money will solve every problem
