I would not even want to have a completely cashless society in us. First of all, it should be noted that in any case the currencies of states will play a significant role in non-cash payments in the future. However, unlike paper money, non-cash money allows you to track the balance of each person to the last cent or other national currency. And in many cases, paper money is very convenient to use. People need to be given freedom of choice in the use of forms of cash payments. Cryptocurrency will circulate in society as an alternative means of payment, and it is difficult to determine how much of it will be in demand in the end.
