Quick follow up re Coinjar rewards points, if anyone is considering using their service:

You earn 500 CoinJar Rewards points per every Bitcoin traded, so if you trade 0.5 BTC that would earn you 250 points.

You earn 5 Coinjar Rewards points for every purchase you make with the Coinjar Swipe card, regardless of the transaction amount.

I might make Part 3 into a successful example of buying BTC low and then loading up the card when it is trading high.

I surmise that the way to profit from BTC price movements is to use the above strategy in a bull market, and use the hedge account in a bear market - one would buy high, then hedge to avoid losses down the track. Actually being able to predict a bear market in BTC is of course very tricky, and might not happen for a long time, if ever (?)
