If Bitcoins were introduced in banks, there'd be probably a different protocol made by banks if I'm correct? What would it be like?
If it was introduced in banks, of course they will not allow it to become a decentralized cryptocurrency because it cuts all the purpose of the banks which is being the middleman and allowing all people to make transactions directly without the needs of their service. They will change it to a centralized coin and people will still need to provide their information to own Bitcoin, of course they will not allow owning it anonymously because they will not be able to tax people.
