The whole Speculation board is filled with shills with an agenda, whether it's up or down, many people post there trying to influence the market. And it works, Bitcoin is very susceptible to good or bad news.
A topic like Bitcoint to $1,800 USD by end of 2018 (note the "t" at the end of Bitcoin in the title) shouldn't be in Bitcoin Discussion. It's nothing more than a linkdump. I've reported it to be moved to either Speculation or Press.
The report linked in this topic about comes from a "Wall Street consultancy", they have an even bigger agenda.
