Those put options are 1. traded on an unregulated exchange and 2. quoted in BTC.. which means when you buy puts they are settled in bitcoin, so when bitcoin is at zero those puts are basically worth zero as well. And even if it drops only to a certain level, when you sell the puts you get bitcoins for it and you still need to get out of those to cash in... All up, there are no proper options on bitcoin for people to short it.
