Question about market cycles and bitcoin halvings

Bitcoin halvings occur roughly every four years and history indicates that they are a key element to kick off a bull market.

Given that the duration of each market cycle has been longer than the previous one so far and if (and that's a big if, I know) we assume that will be the case going forward, won't we end up in a situation where bear markets will be much shorter, and at some point not occur anymore? Would we not be on our way to a never ending supercycle?

For clarification purposes: No, I don't believe that the recent weeks can be described as a bear market, I'd rather consider them as a bearish trend in a bull market. Of course, I might be completely wrong. Even if my supercycle theory is correct, there will always be days/weeks/months where the market will drop, that's just how it goes.

What do you think? I'm curious to hear your thoughts
