Not literally, crypto can stand without having an actual bank. Though we need it somehow in dealing using P2P trades usually a personal Bank account is needed. Yet, there are still P2P traders allowing transactions using another virtual wallet. So yeah, Crypto have its own workaround that Banks have. So nah, even without banks crypto will still move.
indeed without crypto banks can move as they are today, but we do not know what kind of crypto policy will be enforced in the future. we know the government plays an important role, where we cannot avoid the regulations that have been set. actually in crypto everyone has their own bank and must be responsible for the security of their wallet
