During market volatility, the easiest mistake to make is overtrading. Some coins may seem calm on the surface, but actually hide opportunities; rushing to sell them can cause you to miss out on subsequent market movements.

The first category includes those that have experienced a significant rally and then entered consolidation. Don't think the upward trend has ended; quite the opposite, this consolidation often prepares for a larger cycle of growth. Although trading volume may not be as active at this point, the fact that the main players are holding their positions indicates something. Selling easily at this stage could lead to regret during the next upward surge.

The second category involves coins that have gone through several adjustments and recently experienced a new round of decline. The key here is to observe trading volume—if the volume gradually diminishes during the decline, it indicates that selling pressure is weakening and panic has largely been released. Being scared out at this moment is often the most costly mistake.

The third category includes coins with solid positions. They repeatedly consolidate around the annual moving average, and have previously broken out with high volume at the bottom. Although subsequent rises are gentle, during declines they often shrink volume to defend. This pattern strongly suggests that main funds are quietly building positions. Mainstream coins like Ethereum often exhibit this rhythm.

Overall, learning to judge which coins to hold is much more profitable than blindly chasing gains or selling in panic.
