Common trading mistakes in the cryptocurrency market mainly include the following categories:

1. **Emotional Trading**: Being influenced by market fluctuations, blindly chasing prices and selling low, leading to buying high and selling low. When assets like Bitcoin experience severe volatility, investors are prone to making wrong decisions due to panic or greed.

2. **Frequent Trading and Full Positioning**: Over-trading increases transaction costs, while full position trading lacks flexibility, making it difficult to adjust positions once trapped.

3. **Relying on Others' Strategies**: Blindly following trading advice from social media or group chats, lacking independent analysis, which can easily lead to losses due to delayed or misleading information.

4. **Ignoring Risk Management**: Not setting stop-loss and take-profit levels, or over-leveraging, increases the risk of liquidation.

5. **Transfer and Security Mistakes**: Such as transferring to the wrong address, not verifying the network, or neglecting wallet security, leading to permanent loss of assets.

To avoid these mistakes, one should develop a trading plan, control positions, conduct independent analysis, and strengthen security measures.
