Bitcoin's price can be unpredictable after halving events. History shows there's often a dip followed by a recovery. Holding steady or buying more during these times can pay off in the long run.
In the long term, buying is a good decision and indeed after the halving the Bitcoin price will move without any significant movement but if you look at what happened in the past the Bitcoin price after the Halving will increase sharply after several corrections, so for the next few months I am quite optimistic that we will see much higher Bitcoin prices.
I think the price correction that is currently happening is quite normal.
