Something to keep in mind: We are right up against the longest-term trend line (going back to 2011), which has never broken. If history is to repeat itself then this bear market will be over within two months and BTC will start making higher lows.
However, my gut feeling is still bearish in the short- & mid-term. Events that have never happened before should not be treated as impossible, and this trend line could break.
I am holding a conservative amount of bitcoin and small amounts of major altcoins, with an open short position on BTC on bitmex to hedge against further downside.
