Leak a rumor that there has been a fundamental vulnerability in it's crypto implementation and/or a fundamental problem in it's protocol that allows anyone to steal anyone else's funds and/or trivially mine bitcoins. It'd have to look like a legitimate rumor, but this would work because speculators tend to easily spook (at least in other markets) and no one wants some anonymous internet person stealing all of their money.
