As a trader/investor we should expect market dumps at certain periods, it is the nature of the crypto market and can't be eliminated in my opinion.
As for what to expect on the current bitcoin market situation in 2025, there are too many uncertainty, first, the tarrif war has not ceased, panic sellers are doing their things; there are political unrest, the middle east war, market sentiments etc.
However, i am looking at altcoins reasons to happen before the bear market, hopefully, before the end of the year, between November to December, there should be altcoins bull run.
