From history we have seen the same bull over the years, whether for the next year the bull could be in the same position as the previous position the bull came in after the Bitcoin halving after 1, 2 years later or it will change. Elite investors always try to find loopholes in Bitcoin investment by various ways to change processes that don't want to be the same as history, suddenly small investors like me don't meet expectations.
This is also unthinkable. It's possible that the bull run scheme could change, but I'm sure the changes will not be too significant and are still on track. What I have observed is that the percentage increase in % of each bullrun is always different and decreasing, but ATH is still ATH as the highest point. Maybe this can be an anticipation for taking profit or targeting investment sales.
