Haha, don't be so arrogant, when it rises together, you get very anxious,

​to spend every last penny and finish it all

​leaving even half a coin in hand feels like wasting time

​this kind of thinking will only result in 'only going in and not out'

​if there’s still half a position, then just wait to sell them well

​otherwise, not rising is a reason to buy, the real underestimation will indeed be the opportunity

​keep enough bullets in hand, only need to have enough patience to wait, and you can find the perfect entry point.
