So there's this interesting debate happening right now in crypto circles about whether Bitcoin's four-year cycle actually matters anymore. A lot of big names like Matt Hougan from Bitwise and Cathie Wood have been saying the pattern is basically dead - that institutional adoption and ETFs have fundamentally changed how BTC behaves.

But Jurrien Timmer at Fidelity isn't buying it. He's been looking at the charts and the data actually looks pretty convincing to him. The way the market has moved since the 2024 halving seems to follow the same playbook we've seen before. You had that massive rally that peaked in October last year around $125K, and now we're in what looks like a textbook bear phase.

Here's how the crypto 4 year cycle typically works - Bitcoin halvings happen roughly every four years, cutting mining rewards by half. This creates a supply squeeze that usually triggers a big bull run. Then comes the crash, usually somewhere in the 80% range, followed by a grinding recovery toward the next halving. The pattern has held through 2012, 2016, 2020, and it's looking pretty similar for this cycle too.

Timmer's take is straightforward: expect 2026 to be kind of a wash for Bitcoin. He thinks the bear market phase should stick around for about a year, which means we might be looking at weakness extending well into the year. His support level sits somewhere between $65K-$75K, which is where he'd expect buyers to show up if things get really messy.

What's interesting is that even with all the mainstream adoption and regulation we've seen, the underlying crypto 4 year cycle mechanics still seem to be driving price action. Whether that continues to hold as the space matures is probably the real question. For now though, the charts are telling a pretty familiar story - one that suggests patience might be the move for the next several months.
