Yes anything is possible with bitcoin, as its really difficult to predict what will be the price of bitcoin at halving or after halving totally depends on the user adaption.
Yeah, we don't know what will happen in the future, so we just need to believe and hope what bitcoin can happen in the future.
And most of the people believes that bitcoin will rise in the future and it keeps on rising somehow each day but it will also fall again but not too often.
You just have to have faith that the market will do what is best for it, and the value will remain fairly consistent and go up.
