Buying Bitcoin on every drop is always rewarding specially for the long term holders. What investors should be wary of specially beginners or newbies is that it is not wise to go all in on every dip because of greed. It should he a little percent specially on a bearish market. The purpose of this is to always have extra funds to spend in DCA strategies. You may miss out on profits but you won't suffer tons of losses. I used to he greedy at catching bottoms and I learned the hard way which I never wish to happen on anyone else. Oh well, at the end of the day, it is your funds this is just a humble advice )
