$BTC finally punching through $84,800 — not just touching it, actually breaking it. That's the kind of move that shifts things.

If it holds (big if), we'll probably see altcoins wake up again. They've been flat for days, just sitting there while everyone waited to see what $BTC would do. That's usually how it goes — Bitcoin moves first, then the alts follow a few days later once people feel brave again.

Not saying it's guaranteed, but the pattern's pretty consistent. When Bitcoin stops being boring, the rest of the market remembers it exists.
