So after hitting almost $86K, some people took profits or did a bit of short term selling, and the price dropped quickly to around $78K, that drop was most likely a reactionary bit of nervous profit taking. Then, when the price began to pump around $78K, it served like a safety net — if the price maintains there after a sharp dip, it typically indicates there’s great support under it. Here, when the price returned to usually $84K, it proved the selling pressure was only short-term and buyers quickly stepped back.
