Just to clarify: bitcoin cash (BCH) is only sortof worth $700. There aren't any mainstream exchanges accepting BCH deposits right now, so the market for BCH is limited mostly to people on kraken trading BCH with one another there only.
The exchanges that are accepting BCH require 20 confirmations on your BCH deposit before they let you withdraw the BTC/XBT you traded them for. 20 confirmations right now would take multiple days. The exchanges offering this also seem to have pretty lax identity requirements, which is not a great sign.
