I think 2018 will see another artificial, hysteria driven FOMO bitcoin move, possibly rivaling last year's, followed by a second, massive correction which will hopefully yield a more faithful long term price point. The get rich quick guys, mostly outsiders who barely know what crypto is and helped inflate its price to where it went in 2017, jumped out the moment that things got rough (and they jumped out in mass, which is why we saw all time high followed by 50% devaluation). I think if bitcoin stabilizes (which is basically has) and can show a month or so of steady, marginal growth, those people will make a second run at it, creating another stampede effect. The FOMO will be as strong as last time, but it will be even faster (since those people now know the basics - they already have an account on coinbase for instance). They'll have leverage to get other people on board too, since they can point to a chart (they barely understand) and say "look, it went to 20K last time." This will help it spike there even faster. That said, I think it'll spike faster, and it will also turn negative faster too, much for the same reason. A lot of people will make money, and other people will get in too late and lose money on the correction.
