I believe that massive sell off will happen soon which will unlock the door for the bears
There's already that has happened. And that's why we see a big correction coming from $57k which bitcoin was stable at that price.
no one knows the price of bitcoin in the market going forward, not many people can see and take advantage of the current situation well, if you look at the market cycle at the end of each year it always declines and at the beginning of the year the market increases again. The price may be more bearish if the zone breaks but if it doesn't then the bull run is just starting to retest the previous ATH and if it breaks the new ATH will be set
Actually, many sees where the price is heading and also those that are taking advantage of it. It's just a matter of time on what people will do upon classifying that point.
