That's a common scenario in crypto. They wanna ride the rocket when it's already flying, not before the engine is even turned on. Because the risk they can take is very little, they make sure to only ride the trend, but when they decide to join, the trend is near, if not at the peak already. After that, the trend dies down or goes back to normal. But if you believe in the coin, for example, BTC, just buy, accumulate more, don't mind the fluctuations, and hold it long term.
