I wonder how easy it would be to liquidate these bitcoins? I would imagine that Joe Blow tries to liquidate the same amount, alarm bells would ring very loudly.
It is not easy, especially if you don't already have an account at a Bitcoin exchange. See my other comment at https://news.ycombinator.com/item?id=16277833 for more details (tl;dr: we've been looking/signing up for exchanges for over 3 weeks and none have responded to our signup request yet).
