No, I do not think so. For banks and large financial institutions, cryptocurrency is too risky. However, if this happens, then I do not think that we should be afraid of this. If they own a cryptocurrency, then they will take measures to develop it. To strive to have an cryptocurrency of one kind is meaningless, because in that case it will lose all value. And the manipulation of the cryptocurrency market will be anyway. If you know the basic rules of the game in cryptocurrency, then such a manipulation will not be terrible for us.
