Holding cash is a skill; not acting is also a strategy.

Many people lose money not because they chose the wrong coin, but because they 'cannot endure'. When the market moves, they rush to get in, fearing they'll miss out. But true experts can hold cash for a long time, just to wait for a high-certainty opportunity. The crypto world is full of volatility; what it lacks is the patience to filter that volatility. It's better to observe accurately than to observe frequently; frequent trading only dilutes judgment. Learning to wait is the first lesson of cultivation.
