A common mistake for beginners is to get fully invested and then get hit, only to quickly run away as soon as they break even:

1. Every time Bitcoin pulls back, it's a good opportunity to assess the strength of altcoins. Although some altcoins are weak, there are still many that outperform Bitcoin or move in sync with it during this round;

2. Referencing the first point, a cutting strategy can be used.

If the market goes down to explore further, I will buy back all my positions. If there isn't a significant drop, I will gradually look for the bottoms in smaller ranges to buy.

When fully invested, I call this averaging down, and after reopening, I call this gradually buying the dip.
