That is fine, one of the most common phrases you are going to hear as a trader is to catch the bottom and to sell at the top, but honestly no one really knows where those points are and anyone telling you that is lying, during the bull run of 2017 when bitcoin touched 2k many were predicting a crash and sold their coins only to be surprised by bitcoin reaching 10x that price, as such the only thing that should worry you is if you get profits our of your trades and if you did then you are doing the correct thing despite whatever other traders may say.
