IMHO uncertainty has been drastically reduced. There are enough people out there who understand Bitcoins purpose and role that it has long since passed the passing fad test. This isnt Linden dollars.
Uncertainty has been reduced for most of us because this isn't our first rodeo. People like my parents, OTOH, are pretty sure bitcoin is dead. The recovery from this bear market may change things, as all eyes have been on bitcoin since December.
I would say that the whole of 2017 was pretty damned good for increased attention towards bitcoin, but the bitcoin attention when through the roof from about September 2017 to February-ish 2018.... after about February 2018, there has been some petering out of the attention, and regular people (and even some experienced bitcoiners), have gotten scared. Most of the ones who had gotten in before 2017 have enough equity built up to endure this kind of down period, but you are likely even in better shape if you had gone through a decent amount of 2014-2015.
A little price action, as I type, perhaps? Broke to about $6350 in the past 5-10 minutes.
