It is delusional to think that the price of Bitcoin will continue to fall. This is a clear indication of lack or limited knowledge on how Bitcoin and the entire crypto world works. Sell your valuable BTC now if you buy into this idea and regret later. Perhaps you want to repeat the history of some of the early adopters of BTC who sold their valuable BTC for candies, pizza etc and regretted later.
Bitcoin may well still fall to 2000-2500 dollars, if the bears will not leave the market. But you are right, to think that it will collapse completely is not worth it. Instead of selling, you need to wait for a raise.
