It's possible but highly difficult, and will probably take a very long time, but to be honest, I wish it can happen sooner, but speaking the fact, I doubt if I will ever use a crypto bank if it comes into existence, cus personally, I see no reason to store my crypto in a bank when I can easily store them on my phone using a wallet app or in a hardware wallet if I own one, the idea of crypto bank is kinda useless for me to be sincere.
