I just used my Jaxx wallet with Shapeshift. Sold 10 ETH for 1.4 BTC, then sold the 1.4 BTC for 13.2 ETH tracking the curl down on the ETH to BTC ratio. My January 2018 target for ETH to BTC is 1 to 10, so when it gets more than 20% away from that to either side, I plan to take a position, and wait for it to head closer to 1 to 10.
