Its either they are riding bitcoin's popularity or they are bagholders and trying to influence the next generation of buyers. Usually I look at Mike N. predictions though, this guy has really prediction some good price of bitcoin lately, although he's another big time investors as well, so it would be surprise he makes bold prediction about what will be the price in the future. No one is really sure what the future holds, just recently we had a crash that no one sees' coming. Everything is volatile, but things for sure though, bitcoin will really continue to grow next year and the price could really skyrocketed that some of this predictions may hit, or miss...
