No, I would not intentionally buy a coin that was going down, what I am saying here is that your initial buy was based on a signal that showed a good buy time however instead of going up, the coin went down. This happens a lot to everyone, no one can truly say that every trade they do was in a dip and then went straight up. This just shows you how to handle your trade if you do find yourself in a position where the price has dropped from your initial purchase point and how you can correct that.
