Would you want your bitcoins stored in the vaults of some bank that can freeze your holdings whenever they feel like and for whatever reason?

The banks will never adopt bitcoin, because those that use bitcoins only use bitcoins and other crypto currencies so that they can completely bypass the banks and conduct frictionless, semi anonymous and peer to peer transactions

The banks just cannot compete with the fact that my qt client does EVERYTHING a bank can do, and more... and also gives users the ultimate control over their finances
