The development of the crypto currency from time to time shows a positive direction. More people are getting to know crypto currencies and using crypto currencies for various transactions. The convenience offered by this crypto currency makes people want to continue to use crypto currencies. A lot of cooperation is woven crypto currencies with international businessmen in terms of food or buying and selling goods. But not all countries give legal status to this crypto currency so that the bank's position as a place to store money and financial controllers is still safe and will not be replaced, maybe still in 10 years. But after that the bank must be careful because the presence of crypto currencies is very likely to shift the position of the bank.
