In each bull market of BTC,
there are at least two pullbacks of more than 50%;
at least 10 pullbacks of 20%—30%;
and pullbacks around 10% can occur dozens of times.
Pullbacks of more than 20% are considered risky, as they can liquidate positions with more than 4x leverage.
While clearing leverage, it is also the best opportunity for those who missed out to get on board, so those who missed out need not worry; it's never too late to get on board, what matters is your willingness to take the plunge.
