I think a bull run can occur if the price has reached $ 40k, now the big thing that must be passed by bitcoin is to be able to pass $ 30k, there was a price of $ 31k but not more than a day down again due to profit taking from investors.
You are probably right that bitcoin needs to break resistance and make it a support to start a new trend in the cryptocurrency market. But globally now many coins are at the bottom for a long time. It will not last long and a bull run is bound to happen.
