Based on last year/years bull run, what do you consider to be signals that indicates this kind of movement? Do you see these in nowadays' BTC/Altcoin markets?
Nope. We are still in 2015 of last Bitcoin cycle. Far from 2017, the year you are talking about.
yeah this is true. though the cycle is a lot shorter this time (~9 month bear market as opposed to ~14 month bear market last time), but yeah we're in the equivalent to the spring of 2015 right now.
Probably we'll be in a new bull market sometime in the next 1 - 5 months. End of Q1 2019 at the latest.
It's pretty random if you ask me. We don't know when the whales would start a snowball effect and pump the price to start fomo. It's hard to base when from past bull runs since what caused it then may very well not have the same effect now.
That's true, but like in 2015 there was nothing to push the price up to start a new bull run. Most people still had never heard of bitcoin, there weren't any countries accepting it like Japan in 2017, no halving reward like in 2016, wasn't popular to be talked about in the news constantly like it is now, big institutional money wasn't interesting in it like they are now.
But now there are a lot of things going on for bitcoin that can start the bull market. BAKKT, Fidelity, other Wall St investment or news, ETF acceptance, people simply realizing that we're at the bottom and the time to buy is now, perhaps friendly regulation or more countries accepting it, etc etc. While there is no way to know when it'll start up again, it seems very likely to be soon with new markets opening up and all the attention bitcoin gets. It's not gonna trade sideways for terribly long, no longer than a few months at most I'm sure.
