On how to take profits and exit from altcoins:

1. Look at expectations and market capitalization. For example, if you expect a new coin in the meme sector to reach a market cap of 10 billion this year, then you shouldn't frequently trade the coin you are betting on or constantly check the market. Hold on to it and see if your coin has the potential during a market frenzy. If it really doesn't, don't force it; it just means you made a wrong call, and it's fine to let it go. Misjudging is normal, learn to accept it;

2. Look at patterns and structures. For some older second-tier coins, if they are neither in a hot sector nor have new hype topics, their price increase is likely to be 1) following the overall market, or 2) major funds accumulating at the bottom before driving the price up to release their holdings. At this point, you need to make selling decisions based on their patterns and structures, and remove them from your watchlist if necessary;

3. Look at sectors and main vs. secondary lines. Main storyline coins will have several price increases before reaching a peak; secondary storyline coins tend to have a single flow;

4. Look at the overall market. Bitcoin is the compass of the crypto world, and the U.S. stock market is the guide for Bitcoin. Their movements are determined by the overall economic environment and macro policies. During a bull market, remain sensitive to potential turning points.
