If you think that the history will keep on repeating itself all the time then you are mistaken, badly. First of all we do not fair that well when you look at it year by year and each year having one big move, most of the time it doesn't. Like 2017 was bullish, 18 was bearish but 19 wasn't anything really, we moved a bit but not really a ton.
So, I would suggest that take a look at it in the long term and you should be fine. I personally believe that 22 is more like 19 and we will be just calm and not really have anything big, even considered bearish by some, 23 will be a bit more bullish and 24 will definitely be a huge bullish run.
I am not entirely sure if the cycle you think will happen is any different than the cycle people think it will happen. I mean it was 2014, then 2017 then 2020 seen a good increase as well but kept going until 2021, so something like 2023 could possibly happen. Which is different to what @casteway said in the system but the result is still a bullish season for 2023 so the end result is the same.
This year wasn't a bear right that saw us go down a lot, that is the difference and that is why people are confused but it has been 3 year cycle for a long time and it could very well happen again. Even if we take it 4 years, then it will be 2024 at the latest.
