I highly doubt clients will need to have cryptocurrency knowledge. They're going to be a real bank. Banks don't need cryptocurrency knowledge.
Of course clients will not need to know anything about cryptocurrencies.
Forty Seven Bank will be able to serve both people in the cryptocurrency world and in the fiat world. However if one client only wants to use a part of the service offering, he'll be free to do so.
As our concept is to unite crytpocurrency world and world of traditional monetary economies and build the bridge between them, we will have customers from both communities - some of them will understand cryptocurrencies, some not, but it does not matter, as we will have products and services for both groups of people. Moreover, Forty Seven Bank will become the easiest way for conservative people to find out more about cryptocurrency world and opportunities it might give.
Forty Seven Bank will be the first bank to understand cryprocurrencies and fully support operations with them.
