I just want to share this personal opinion. I don't think that the cryptocurrency will hit ATH this 2018. I might get lots of negative comments from this but at the very least let me share why I think this. We've come from an ATH last 2017 and this 2018, I believe we've reached a rockbottom market. Which means that we're still on our way to recovery. I do believe though that the market will thrive in 2019 (though it's way too early to say at this point in time because so many things are happening to alt coins)
Well, it was bad year, but 2019 may be even worse. The main issue is lack of trust of investors. It slows the development of the market, so we need to unite to fight scams.
