Someone who's a good trader can earn higher profits by shorting Bitcoin with leveraging when it's at the peak. Just think that the ones who shorted Bitcoin when it reached $73.5k a few days ago with 10x leverage have already made a lot profit with it.
not always true though, some trader might blow their entire month's profit in just one trading mistake, most of the trader doesn't just always profit everyday, some of them have occassional pullback as well, even the best trader there is doesn't have 100% win rate, probably just around 70%, which is still good if they can manage their trade with proper SL/TP setup and risk management.
the investor on the other hand, just ignores the market price action and just hold their coin with targeted price, it works flawlessly and the fact that it carries no risk of getting blown up because of trade means if the market is rising high just like how BTC rise from $16k to $70k, they've made so much profit without even the need to risk their capital which i find pretty astonishing.
the thing is, a trader will more likely trade 1-5% of their entire capital's worth for the sake of risk management compared to investor who just invest 100% of their money, so a trader can keep making profit swing trading doesn't mean their portfolio can grow dramatically fast.
