Bitcoin has been in incline since the day it was released. Till now, we saw an increase of 300%, which is impressive no less. On the other hand, Ethereum recorded an incline of 3000%. All of this looks appealing to banks across the planet.
At the moment, all banks offer reserve (electronic form) and cash (physical form). Soon, we will have a new form based on cryptocurrencies, probably Bitcoin. It will be a mixture of two forms used today. As such, people will be able to use cryptocurrencies for retail and financial institutions will use a wholesale version. This implementation has been tested by 40 banks till now.
