Bitcoin starts 2026 with a notably cleaner market structure following the major shake-out at year-end. What's interesting is that profit-taking momentum has cooled considerably—a sign that selling pressure is losing steam. Risk appetite is gradually coming back, though still measured. But here's the catch: for any sustained upside to stick, Bitcoin needs to reclaim those key cost basis levels. Without confirmation at these critical price points, any recovery might just be another false start. The market structure looks healthier, but the test ahead will be whether buyers can hold the line.
