Still, I do not believe in such predictions although I hope it will be true. We all know that there is no correct exact predictions on bitcoin price, so we should not rely on above prediction in order to invest our money in bitcoin. This kind of predictions makes some people who do not have any experiences will do everything to buy bitcoin as much as possible in a hope to multiply their money in short time. It is OK to read predictions but we should be more realistic.
I have much higher expectations for bitcoin price in 5 years, next year halving will make my expectations closer I believe with very nice price rise. I believe that price can go to $100k easily in 2020-2021.
