You're absolutely right. For example, it’s convenient for me to use cryptocurrency in order to quickly and inexpensively transfer money to another person, regardless of where he lives. I often have to make payments and send money to people in other countries, and it would not be convenient for me to do this with my bank card because of the high fees for one transaction. By the way, I must say that a bank transfer can be processed for several days, but a transaction, for example, Ethereum, can take several seconds or minutes, depending on the network load.
