Just a quick chart trick I've been using — split your screen, throw $BTC on one side, cycle through alts on the other.

Super easy to spot which ones have actual relative strength in real time. Like when $BTC keeps making lower lows but some alt is stubbornly holding higher lows? That's your signal.

Especially useful for bottom fishing. If something just refuses to drop further while everything else is bleeding, that's usually the one that rips hardest when the selling pressure finally lifts.

Simple but works.
