Anything is possible when it comes to Bitcoin, but I think you’re pretty confident with your investment given the current price. The fact is that you are not at any loss (currently), and you have the choice to continue to hold or to take quite a nice profit that you have made so far.

As others have said, in the short term we can expect such corrections to happen - this is perfectly normal. In the long run, BTC has always shown that it is profitable, especially in the time after the halving we are currently in. Consequently, next year should be one in which great things happen - but that is only an assumption based on what has been in the past.
