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.
