Never chase high prices, even if you miss out. This is a principle that leeks must know. Many people think that if the price falls, they will not buy it, and if it goes sideways, they will not buy it. But if there is a slight sign of price increase, they will chase it. Then, after you chase it, the price starts to fall again, which completely destroys your mentality and makes you cut your losses back and forth. So remember not to chase the price increase, and think that buying at a reasonable price is the best way to go.
