This is one of the examples of telling people "I will buy once it will dump and dip".
Emotions, when the price is already pumped or high for you, you are telling yourself to buy when it will pull back or dump.
This is difficult and I admit that I am always experiencing this. We don't know how deep the dip is.

That's why the best thing to do when you want buy the dip, try to not do 1 buy or all in, try to average it on multiple buy orders incase there are/is more dip or no more dip. Just my 2 cents.
