I don't think $66k is the deepest as the price could decline further. Moreover, the price now shows no signs of increasing again. Everything can still happen, so prepare for something worse than now.

The price may continue declining until it is time for the halving. After the halving, the price will go sideways until people get bored waiting. Only then will the price increase slowly from up to down.

When people don't think much about the price of Bitcoin, that's when the price of Bitcoin can start to increase rapidly.
