Waiting to buy lower is a newbie tactic which will almost always make you miss out on the pump and lose money. Its been tried many many times and any veteran trader would advise against this kind of thoughtless tactic.

The best strategy (From my own subjective perspective) would be to DCA each dip. I for example would DCA the next weekly bottom (which has yet to show itself, I believe).

But you can also DCA every daily dip or even every hourly dip. 

From my experience 3-4 consecutive dips are the norm before we see a bull market again on the weekly. I would guess to wager that this current dip might be the last of pre-last.
