Just been looking at the charts and honestly the bearish flag pattern on BTC is getting harder to ignore. We're sitting around $66.96K right now, down pretty hard from that $126K peak we hit a few months back. A lot of traders are starting to think this bull run might actually be done.

The thing that's got me concerned is the four-year cycle data. Bitcoin usually peaks around 530 days after halving, and if that model holds, we could already be deep into a bear market heading into 2026. Looking at history, these bear phases can drag on for close to a year. The 200-week moving average is hovering near $57K - that's a 55% drop from the peak and probably the next real support to watch.

What's wild is some old Bitcoin whale just moved 909 BTC after sitting dormant for over a decade. That's like $85 million worth, and it's adding to the selling pressure. Meanwhile, if the broader markets start to crack, we could see Bitcoin revisit that $57K zone pretty quick. Past cycles show when Nasdaq drops 15-20%, Bitcoin usually falls 30-40%, so macro risk is definitely a factor.

Altcoins would probably get hit even harder if this turns into a real correction. Ethereum's historically dropped 80-90% in bear markets, so that $1K level could be on the table. I'm not saying it's guaranteed to happen, but the setup is looking sketchy right now. Just keeping an eye on where that $91K weekly support holds.
