Bull market, simply put, means that the overall trend is going up rapidly, and the fluctuations are definitely large.
Altcoins usually fluctuate around 10%, which is considered a lot. Now that the bull market has arrived, fluctuations of 15%-20% are not a big deal.
Altcoins have now broken through the support level and are starting to enter an unmanaged area. High market cap coins might correct by 75%, while low market cap ones might even return to the starting point. But don't think the bull market is over just because it drops; that would be a huge loss. Remember, in a bull market, going long means even if you're stuck, there's still a chance to break free; but if you go short and get stuck, you might as well wait for liquidation.
If you have long positions, don't rush to cut losses; if you sell and it goes back up later, you'll regret it. Wait for a strong reversal signal, then increase your position to lower the average price of your long positions. This way, you can welcome the cryptocurrency frenzy after Trump takes office next year.
If you don't have long positions, or if you haven't made money recently, don't rush either. Patiently wait for a reversal signal; when that time comes to buy, you'll be buying in the 'golden pit' of the bull market, with an excellent position. Definitely don't rush to buy just because of a big drop; the bull market is for those who are patient.
