The price breakout for Bitcoin Gold is most likely a long with some returns. It is medium to high risk but still very investible until 3rd quarter 2018. While it isn't as investible as BTC as a short or conservative as long, the potential is higher given more demand breakout. Also the resistance level has potential for a long run maximized trade strategy throughout 2018 to mid 2019. For a short position that is less then 2 to 3 month, it is expected to have higher risks or negative correlations.
I hope to miss it soon
