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.
Actually when bitcoin or altcoin price pump many trader or investors hope bitcoin or altcoin price could dip few while to buy back, but when the moment of price dip why many trader or investor not brave for buy back and try to add bag with many altcoin choose. Later when price have recovery and bitcoin back to higher again we found many disappointed from investor or trader statement, why not buy back yesterday when bitcoin and altcoin still dump. They have not brave when get chance and always fraud with bitcoin dump, how ever that the good beginning to buy back when price dump.
