A bitcoin bank is a contradiction in terms, since the blockchain is already a bank. In addition, in this operation there are many obscure points, so it seems to me a good and good scam. We'll see how it turns out.
Certainly no doubt it is a huge contradiction, considering the fact that as a cryptocurrency user, you are meant to be your own bank without the involvement of a third party, but we still have to realize that in as much as it could be easy for some of us, there is still a chance that some will really find it hard, so in that way, if banks want to be involved in the space, to at least service the latter, then I guess there is a lot of room for everyone and then a chance for the space to grow further.
However, at this stage, I really do not expect any smart person who is a tech savvy to obviously trust the banks over their own judgment to keep their funds for them.
