What about a BTC options trade or sorts, there must be some sort of financial product whereby you can hedge i.e go short and cover your long BTC exposure??
Like a BTC put option?

http://btclevels.com/ might be of interest or is there an alternative?
As soon as it is available, bitshares aims to do just that. Protoshares are being mined now for that.
