New year, fresh momentum. Bitcoin just hit its highest price since November, and it's pretty clear the market's starting to wake up again.

But here's what really matters right now—there's a critical support zone everyone should be watching: the $90-91K area, which also lines up with the 21-day moving average. That's the line in the sand. If buyers hold it, we could see some serious continuation. Break below? That's when things get interesting in the other direction.

The slow grind is building into real moves. Keep an eye on that level.
