Your strategies seem to be following the trends. It would be interesting to test 'buy the dip' strategies, eg:

Strat 1

Filter: Top 30 coin over last 26 weeks (i.e. quality)
Action: Sell when price rises 20% above average price movement of all other quality coins.
Buy when price falls 20% below average price movement of all other quality coins.

Strat 2:

Filter: Randomly choose 20 coins from top 100
Action: Same as strat 1 (to test difference)
