Bitcoin cycles:

2013:
Bull: ~9 months (starting after a new ATH)
Bear: XX months

2017:

Bull: ~10 months (starting after a new ATH)
Bear: XX months

2021:
Bull: XX months
Bear: XX months

2024:

We’re in month 15th now

Each bull cycle gets longer, each bear market gets shorter.

That’s why it’s hard to rely on the duration of the bull run after a new ATH - it’s a different number every time.

But one thing stays the same:

- Every ATH hits in November/December

2013: ATH in December

2017: ATH in December

2021: ATH in November

2025? Pattern says we have X months...
