It is already looking like a dip considering the realities on ground.  Firstly, Bitcoin has shown obvious reluctance to go below $60k and have been hovering around $70k, this should be an indication that price lingering around the high of 2021 is just a case of resistance turn into support. I don't want to sound so much like a trader but it is what it is.

Secondly, Bitcoin halving is just around the corner and Bitcoin remaining around the 2021 high, it will be a kind of unusual to expect price to dip so hard. Therefore,  $66k is indeed a dip that anyone should consider buying at lump sum while we wait to see what the halving is bringing to the table.
