It depends how much money we are talking about and what kind of wallet? If it is a paper wallet locked in a secure fire safe vault guarded by an army then I'd say a wallet. If it is a digital wallet, then a bank that is insured by the FDIC. I think banks have a very different agenda from Bitcoin holders who are benefiting from the long term fundamentals of the currency. Banks are direct beneficiaries of a fractional-reserve currency system.
