It seems like you either have a limited understanding of investments or you're relatively new to this world. When people see prices rising, they may feel a sense of FOMO (fear of missing out) and make impulsive decisions to buy at a high price. On the other hand, when prices are low, they may be uncertain or skeptical about the market and choose to wait for a rebound. But the most important thing is that no one can know in advance when the prices are too high and when they are low. Timing the market is a difficult task and is often impossible to predict with certainty. Therefore, it's recommended to focus on a long-term investment strategy, instead of trying to time the market.
