Here's an idea. Ethereum smart contracts to short bitcoin. You borrow my BTC for 30 days, with a 5% fee. Someone could make a killing off of that idea.

Note: I'm not affiliated with that project, but I did see them present yesterday at Token Summit and it looked very interesting!

This is more of a general purpose app, but would work.

I used to short/long bitcoin/eth on GDAX, you have to register as a business and turn on Margin Trading
