Cycle comparison: The current cycle most closely mirrors two past ones—2011-2013 (the double peak cycle) and 2015-2017 (the slow and steady rise).
to correct you
2011 was part of the 2009-2012 cycle, 2013 was part of the 2012-2016 cycle
2015 is part of the 2012-2016 cycle, 2017 is part of the 2016-2020 cycle
2011 ATH is due to 1 year after first market
2013 ATH is due to 1 year after first halving
2017 ATH is due to 1 year after second halving
the 2015 lull period is the pre-halving boring period which can be seen happening again in 2019 and again in 2023
the stead rise of 2016-17 was the halving+lead to ATH, which can also be seen in 2012-13 and 2020-21 and yes we are in this period now 2024-25
Going by some of the history of bitcoin circle, you're going to definitely find or discover some similarities in them, this is because sometime the pattern follows suit on a regular basis while on some cases it is not as the same from the previous ones, but there are thing to deduce when comparing more than two circles together relating to the bitcoin market price and the bullrun run pattern used during those periods.
the patterns emerge due to the economics of the costs of mining that change due to certain fixed events(halving) and then the accounting those with costs do after the halving to then express the prices they need to push to cover those costs after the fact.
its then bots which are trained to follow the pattern, that then enforce the pattern(at first), but then some traders then knowing the pattern is going to occur then trade pre-emptively to the pattern, causing the pattern to move slightly as more and more people learn and try to take advantage of the pattern, thus end up causing trades to change the pattern the more people try to act predictably against the pattern
there will still be the main fixed milestones which will always trigger some movement due to basic underlying economics, but the more traders train their bots to act before during and after the natural triggers, the less pronounced the results get. in short the multiplier height of a ATH or a correction smooths/lengthens out instead of being FOMO moments in short period
