As it is based on speculation, it is unpredictable. No one can tell but from previous events or occurrences in the past of bitcoin halving, there has been a surge in bitcoin price immediately after bitcoin halving so it would not be a surprise if such should happen this time but still yet, nobody knows if the reverse would be the case. Moreover, there are several factors driving the Bitcoin market, and if they come into play the next halving would be of big significant effect on the crypto community would would further drive the demand for bitcoin as the price surges high above the last ATH.
We cannot predict exactly where bitcoin will go and can only guess.
And many people have been wrong in guessing or giving their predictions because bitcoin's movements are now wilder.
But it is true that after a halving, there will usually be a spike in the price of bitcoin, which will be the moment to sell it at a high price.
So we can only presume that the next halving could trigger the bitcoin price to skyrocket and even surpass the last ATH price.
If that does happen, we can certainly make huge profits from bitcoin but that's only for people who already own a lot of bitcoin.
