That's what i also wonder that how people are busy making lame excuses always when Bitcoin prices are low - "that it's not going to survive and it will be dead" and when the prices are high they say - "we miss the boat" and this will continue as always.
I believe in the theory that these are mostly people who want short-term profits, and when the price is low and relatively stable then they have no motive to invest - and when it is as high as lately, then they wait for a big correction to happen. These are actually very indecisive people, not only about Bitcoin, but mostly about everything they do in life. I know some such people in real life, and I stopped trying to understand them a long time ago - if you've been talking about something for 5+ years and you haven't done anything to make it happen, then no one can help you.
People wait for something revolutionary to happen and when they have it in front of them they have it they just ignore it like anything has not happened yet.Same is the case with these people and they will always have two sided lame excuses which hinders them to see the harsh reality that governments are the ones that don't want the country and people to grow and everything they are doing is for their own personal benefits only.
But still we can't say that we will see less or more of these kind of people and the simple is to just put them aside and keep going the way you find it suitable to progress and for us it's bitcoin that is the best option available to the society.
