2021 was a speculative bubble, there are a lot of people with a lot of money they might splash on bitcoin again, but these things are very random and unpredictable, like gambling really.
Uncertainty about the economy and real estate market might be factors in the current bear market, they need the money for other things, covid lockdowns and boredom might have introduced people to bitcoin and coaxed them into it and now that's over they've lost interest. This is all speculation though.
However considering the amount of money that was poured into bitcoin earlier there is a possibility it will rise again. I am a low risk investor so I only bought when it dipped below $20k which seems to be the rock bottom level.
