I often look @onchainfx using the "% down from ATH" filter, as the "least down" and "most down" both give valuable information. onchainfx.com 
For the most part, in a bear market "least down" reveals tight-knit resilient communities, which can set them up to rebound quickly when sentiment turns.
"Most down" can either show you what was bad to begin with, or #cryptoassets that are being thrown out with the bathwater. For the latter, mean-reversion can be your friend.
