Investors’ behavior has a significant impact on digital currency prices, which is mainly reflected in the following aspects:

1. **Buying or selling in large quantities**: When investors buy a certain digital currency on a large scale, rising demand drives up the price; conversely, concentrated selling increases supply, causing the price to fall.

2. **Influence of market sentiment**: Fluctuations in market sentiment quickly affect price trends. Optimism drives more people to buy, pushing up prices; pessimism may trigger panic selling, pushing prices down. Social media and news dissemination amplify the impact of this sentiment.

3. **Chasing the rise and killing the fall**: Some investors tend to chase the rise and kill the fall. They follow the trend and buy when the price rises, and panic sell when the price falls. This behavior increases market volatility and has a direct impact on price movements.

4. **Long-term holding or selling**: Investors who hold coins for a long time tend to have full confidence in digital currencies, which helps stabilize the market. And a massive sell-off can trigger panic, causing prices to fall rapidly.

In general, investors' buying and selling behavior, emotional fluctuations, psychology of chasing ups and downs, and decisions to hold or sell coins will affect the price trend of digital currencies through changes in supply and demand, emotional guidance, etc.
