Currently no body can tell the price bitcoin will be in the future because the Bitcoin is not a stable coin as it fluctuate every given time. I think those people are just doing the normal thing which is guessing, no body can tell the future likewise the future price of Bitcoin. I think this is just trying to make traffic so that many people could keep buying and holding Bitcoin which is not bad but the fact that those predictions are concern, we won't know the closet  prediction until the end of the year.
