Difficult to say. History often repeats itself and because of this I expect some kind of a selfullfilling prophecy: a dump right after the halving. This might go some days or even weeks. I hope I can rebuy at around 5-6k Level!
But you know it, it's risky and because we are all expecting a dump after halving, it could go the opposite way round. Whales like to milk us small fishes ...
