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.
At some point we need to take the risk, I understand why people are afraid to do it as everyone experiments the same at some point during their trading careers but if someone cannot overcome this then it is better to stop trading as sooner or later this is going to cost them a lot of money, traders need to have a defined strategy that tells them when to get in and when to get out of the market, and when those levels are reached then they need to act upon their own signals and stop thinking about what could happen if the price keeps dumping and stuff like that.
