Ever since the 2017 boom a lot of people around the world have known about Bitcoin. Sure the vast majority didn't buy any, but a significant amount of people have known about Bitcoin since 2017, they know it shoots up and then crashes. Many of them still don't even realize it has done this plenty of times before 2017, they still think 2017 was THE big bubble and now its crashed and that's that for Bitcoin. People tend to be fear focused investors when it comes to Bitcoin and so most people haven't invested in Bitcoin because they just assume it will crash again (funny example: I had a coworker a year ago, when Bitcoin was sitting at the bottom, tell me he would surely buy Bitcoin once it crashes...needless to say I looked at him strangely as I made another purchase at the bottom) - they focus on the crashes not the gains or the overall uptrend picture.
first of all i do believe that bitcoin price doesn't go up because of some arbitrary cycle and definitely not because of what some people think. instead it continues to go up because as the adoption grows the demand for this scarce currency increases. and that causes this type of cycles as there is a big adoption that leads to a big rise and since that causes a bubble in this small market, it is naturally followed by a bear run.
as for your theory it sounds to me to be THE reason for seeing an even bigger rise. in other words your theory may be correct but your conclusion is not.
the same reasons you mentioned (people knowing what happened in the past) is the reason why they do FOMO in the future. they have seen such cycles where price goes from $11 to $1200 or from $150 to $20000 or in other words 11000% and 13000% rise in 3 years and they have already seen the start of the same cycle yet another time ($3200 to $13000). it would be logical for them to jump on board so that they won't miss yet another cycle. so we could see a much bigger bubble this time, maybe 50000% rise ($1.6 million).
i know $1.6 million sounds big right now but $20k was also looking big when price was $150 so was $1200 when it was $11 and so w as $11 when price was $0.01
Answer to First paragraph:
What you are describing is FOMO. The cycles aren't arbitrary, they are created by FOMO and fear. No where did I say the cycles are created arbitrarily or because of what some people think. The giant booms and busts of the cycles are FOMO and fear. But of course those things are driven by by what people think/feel - "oh my god I gotta get in now I'll make a ton of money" or "oh no I'm losing money I gotta sell it all now!"
Answer to Second paragraph:
I think you're missing the point that the average person views bitcoin as "it always crashes". People buy into FOMO because they see a skyrocketing price and they don't know any better. Most people who buy into it late in the bull market and then end up losing money as it crashes are doing so because they just found out about Bitcoin and they hear how everyone is making money and so they jump in. What I'm saying is that after 2017, for the first time, a very significant amount of the internet-going population has already heard of bitcoin and while they know it goes up a ton they are skeptical and their general view of bitcoin is "it always crashes", not "it always makes people tons of money", even though the long term results support the latter statement.
These people who simply have heard of bitcoin and know a little bit about it, who could consist of the new money in the future, don't know intricate details of bitcoin or its price history. Most of them think it was just a single bubble that occurred in 2017 and now it is crashing down. Also they don't focus on the huge gains, as you do above, they focus on the huge crashes. They focus on how people who bought into the FOMO then watched the price crash 80% and suffer huge losses. That's what they focus on. Because anybody who focuses on the huge gains of bitcoin is already in Bitcoin! Because if you understand Bitcoin's potential for such massive gains you're already gonna be owning bitcoin! Of course more and more of these people will get a more proper understanding of Bitcoin in time, but in terms of new money buying into FOMO this new money thinks "bitcoin always crashes" now that they know what Bitcoin is thanks to 2017/2018. So it is very possible they will gradually come in on succeeding smaller cycles rather than all piling in on one big 4 year cycle. And it is very possible because they view bitcoin as always crashing, that new money will get in and out quicker than before, counting themselves lucky for not getting caught in a crash, making smaller shorter cycles where the FOMO doesn't allow the price to build up nearly as much as previously.
