Trend momentum
Momentum, but only while Bitcoin is in an uptrend.
How it works
Every month, buy the five liquid coins with the highest 90-day return that trade above their 200-day average, and move to cash whenever Bitcoin closes below its own 200-day average.
The idea
Almost every coin falls when Bitcoin does. Waiting out Bitcoin's downtrends avoids most of the crashes that hurt momentum, at the cost of some false alarms.
