Assuming that HIVE it's your only alt, the rule of thumb would be.
Sell 70-80% at the top for stablecoins (and the 20% remaining a bit more patiently).
At the bottom start DCA into Bitcoin. Remember that blogging rewards were very high at the bottom in HIVE terms, so this will be the moment to accumulate like mad.
