it seems, the current conditions, people who have bitcoins are very difficult to sell the bitcoins they have, except in a state of urgency.
rumors that prices could go as high as $70k to $100k have really been seen. this is different from a few years ago when bitcoin prices were still quite cheap. currently the price of bitcoin is very expensive, and tends to rise continuously. however, if it wasn't in a state of urgency, or business, I think people would continue to hold the bitcoins they own.
personally I currently don't have bitcoins. however, even when I own an altcoin, I don't want to sell it right now.
obviously in a pretty good bitcoin situation, of course, if there is no urgent need, it seems like it would be a loss to sell it. Moreover, the current situation of bitcoin is indeed not very stable, because every time it reaches renewable ATH, bitcoin will make a very deep correction and to surpass the old ATH it seems now rather difficult to do.
the momentum that bitcoin has to do is really hit $70K first because this value hasn't been exceeded for a while, after that it just started to reach higher values and as you said and many have predicted that $100K will be reached by the end of this year, but there should be a move towards $70K first. we wait patiently for it because bitcoin will be able to do even though the time is very near.
