The speed of sector rotation is very fast; the greatest fear is not buying incorrectly, but rather missing the best entry opportunity or failing to keep up with the rhythm.
In a bull market, choosing leading coins for operation is relatively safe, and using leverage moderately can fully seize the opportunity for upward movements. For other coins, one can choose to follow the trend and gradually lay out positions, or make timely adjustments and switches.
For market-making coins, especially WM types, all stop-loss points will be tested before the launch; just patiently wait for the opportunity.
