Let's be honest, market do not follow any rules. There is no rule or law that says BTC should reach another ATH next cycle and next after. What if 69K was the maximum it could reach, and for the next years or decades it will be mostly fluctuating between 15k and let's say 40k.
Like what you said also, there will also be no rules that will make Bitcoin follow what you say with prices only rotating in that range. If you think that every bitcoin reaches the latest ATH just because of a 4 year cycle that is wrong, because what makes the price reach ATH is that many people have an interest in being able to see the btc price reach highs again and again, including miners who have spent large sums of money to mine and they need returns so that they remain profitable, also big institutions that invest in bitcoin by owning large amounts they have not only want to own but because they want to make a profit by making the price higher than the purchase price, so the increase in the price of bitcoin is a concern for many parties.
