Not only experts believe that Bitcoin is experiencing a temporary decline in price, but people who are experienced in the crypto world will think the same. Because if we study the movement of Bitcoin, every time the price falls, it will always recover, that's because of the high demand for Bitcoin. Therefore we do not need to worry about the current bearish trend, I prefer long-term holding for Bitcoin if it is in a bearish situation like now. However, if we plan to buy altcoins, it is better for daily trade. Because the movement of altcoins is more difficult to predict, so it is more risky to hold for the long term.
Unfortunately people do not understand the "it will always recover" part that you talked about. Yes you understand it, and yes I understand it as well, but there are so many people out there who do not understand what it means and they keep on failing a lot as well. I personally like the fact that bitcoin is a great thing to make money from, and when it is low that means I could invest and make a great return.
But, there are some people who have been here not long enough to know this, and they see something that crashed from 68k to 26k at the bottom, meaning that it crashed like 60% or so, and that is a horrible feeling and they get out fearing they will lose even further.
