Just mapped out the last crypto bull run patterns over the past decade, and it's pretty fascinating how consistent the cycles actually are.

Looking back, we've had roughly 5 major bull runs since 2015. The 2015-2016 run took BTC from around $152 to $780 over 17 months. Then 2017 hit different – that was the year everyone and their grandma got into crypto, pushing BTC from $1k to nearly $20k in just 12 months. Absolute madness.

But the real monster? The 2020-2021 cycle. Started from the COVID crash bottom around $3,850 in March 2020, and didn't peak until November 2021 at roughly $69k. That's 20 months of sustained growth. Most people only remember the November peak, but the real story is how long that rally held.

Then more recently, the last crypto bull run kicked off in early 2023 after the FTX mess settled down. BTC climbed from $16,500 all the way to $73,738 by March 2024 – about 14 months of action.

Now here's where it gets interesting. Bitcoin's halving happened back in April 2024, and historically the next leg up starts 6-12 months after. So we should be watching late 2025 into 2026. If the pattern holds, we could see another significant move then.

The pattern is pretty clear: each cycle starts right after a major market bottom, runs for 12-20 months with parabolic moves, then enters a long consolidation phase. Some exchanges might log slightly different peak dates, but the macro trend is consistent.

Currently BTC is sitting around $77.96k, so we're already well above those previous cycle peaks. Definitely worth keeping an eye on how this next phase develops.
