The answer is the same: nobody knows it. As of now, the market is still going down. It could reach $12k, maybe. Nobody knows! If it goes, I will sell my Bitcoin and buy it again.
Is it the right decision, you should think carefully. As you say, no one can know whether bitcoin will go up or down, selling bitcoin now and waiting to buy it back at a lower price is too risky. We are in a bear market but there is nothing to say that bitcoin will break $17k again, probably won't happen. If you still have money and wait for the price to drop further to buy then I have no idea, but selling immediately and waiting to buy it back at a lower price is not recommended.
It comes to the idea that selling now and waiting for the next drop is kinda be optional. What I mean is that we can just do selling if we see a profit on it and use this money to reinvest. But as the situation is dropping more, I suggest staying on hold, and instead of thinking of waiting for the price to pump, it is better to take the current situation as an opportunity to buy more while waiting for the recovery. It was uncertain what comes next that is why we should be wise enough and think several times before making a step.
