There are many answers to this question and I am looking forward to see everyone's opinion.
all we know is that it will rise price, but we don't know by how much, it will depend on price that we will have before halving, but i am pretty sure that it won't be more than 2x price rise, for example if we will have 600$ before halving, we will have up to 1200$ after halving, but this price would be awesome too
I think we will have $500 before halving. After halving the price will be $800. The by year end, the price will be $1500.
