Step 1: buy TSLA puts
Step 2: @elonmusk: "I'm retiring effective immediately. Don't believe what you read in the news tomorrow."

It's an ocean of contracts out there.
My guess is it would trend downward since my evaluation of $tsla is that it is a personality driven bubble; but my evaluation isn't everyone else's.
And if you really want to be pedantic, the hacker has made $0 from it so far, since the Bitcoins haven't been transferred anywhere to cash out. Which is pretty easy to beat :-p
