If we get to a new ATH things could get really crazy really fast.
We're barely getting any publicity right now. I have the same thought, whereas we're going to get 2017 levels of mass publicity once bitcoin has broken above ATH, as bitcoin would probably be all over the news by then. And with that, I'm also kinda expecting 2017 levels of a price bubble; fortunately and unfortunately.
Well, Bitcoin made it up to $16k slower and without that much hype this time. I honestly don't understand what brought it that high after all these years, but I think that if there's less hype over it now than in 2017, it's a good thing. I believe that because broad media coverage encourages newbies to buy out of FOMO, and then they start panic selling once the price gets a bit lower, causing a huge drop. Maybe this won't happen this time. It would be nice if it doesn't because I don't want 2018 all over again. I think Bitcoin might reach $20k by the end of 2020, but I'm not sure I want it to. The price is already very good, and slower growth or even stabilization is preferable, as for me.
