Are Passwords Robust Enough to Protect Your Bitcoins?

Still, it is always preferable to use a different key pair for authentication, signing or rather, non-repudiation and encryption. If you have to create your own protocol for, for instance, homomorphic encryption, where raw primitives are more common then sure, remember Bruce's advice.

Bruce Schneier, encryption, public keys and digital-signature.

However, I don't think offering a token amount of money even in the form of bitcoins is appropriate. A real, professional security review of bitcoin would take a lot of time and a lot of money.

I understand that's not what is being asked, but asking Mr. Schneier to write about bitcoin is really an irrational "Appeal to Authority" -- I think he'd say that any cryptography-related technology is never proven secure, but only gains trust by having multiple people and groups of people look at it, imagine potential attacks, try to attack it, etc.
