Bitcoin just carved out a fresh support zone right at the $80K mark. What's interesting? The cost-basis heatmap is lighting up with activity – tons of coins got scooped up during today's dip, all clustered around that low-$80K range.

Here's why this matters: when buyers pile in at a specific price level, they've got skin in the game. They're not gonna let it slide below their entry without a fight. That psychological anchor tends to hold strong, especially when the volume's this concentrated.

So yeah, $80K isn't just a round number anymore. It's shaping up as a legit line in the sand that recent buyers will probably defend tooth and nail. Keep an eye on how price action behaves around this zone – could tell us a lot about what's next.
