I have the same thing in mind. This is why I've said a decent number of times here on Bitcointalk that I think we're going to get a drop in price in the short term after the halving, as there's a significant number of people counting on a price pump after the halving for some reason...
Definitely some people see BTC as another asset they can profit from, but they don't want to invest in the long run, but are waiting for some moment like the upcoming halving. This is quite understandable given the volatility that BTC has, and it is a
quick in quick out method, which sometimes pays off and sometimes it doesn't. There is no doubt that some investors might be disappointed after halving because they expect a big pump, but on the other hand it may happen. I think a bigger FOMO might be missing out if we don't reach $10 000, because the media certainly will not be too interested in this story unless they have the material to clickbait headlines.
That is not why it is interesting to me. It's not even true. (I challenge you to explain it using real economic theory).
It may not be true in the literal sense of the word, but one average user understands it that way. People are not too interested (or generally lacking the necessary knowledge) to engage in discussions at this level. Most people can't or don't want to understand the technical or economic side of the story at all, and it comes down to
"tell me when to buy and when to sell". The only time they don't ask for advice is right now, because they expect the past will repeat itself and that they will have easy profit.
Every trend becomes broken sooner or later, otherwise the price would be too predictable. I'd say it already happened year ago, when the price went from 3k to 14k without any real reason. So I totally expect that this time it will be somehow different - maybe new ATH will come sooner than expected or won't come at all, maybe there will be a bearish market, or maybe a big bull run will start in just next few days. Either way, Bitcoin was always doing something unexpected, and right now everyone expect a repetition of 2016-2017.
I would disagree that there was no reason, but other than some theories that have been made public, we may never know what the real reason was. The theory that everything was cooked up by Bakkt was quite popular back then, which of course may not be true. Anything you mentioned can happen, and I would just add a pandemic factor that will certainly play a big role in how BTC will behave as experts say in the recession that is at the door, and it should be much more dangerous than one started in 2008.
