Such questions will be asked a lot, but how it is convenient to pay such currencies, which can change their price from 10 percent or more per day in the direction of growth or in the direction of decline.

I think cryptocurrency will be used in the near future as an alternative method of payment, and to replace the money in the near future will be used coins tied to Fiat or material values with low volatility (for example, gold).
