Major institutional player Grayscale believes Bitcoin is approaching the end of its four-year market cycle, with potential for a new all-time high as soon as early 2026. The investment firm's latest analysis points to January as a critical period where we could see BTC break through previous resistance levels. This cyclical pattern has historically guided Bitcoin's major bull runs, and if Grayscale's thesis holds, the H1 2026 period could mark a significant inflection point. The convergence of technical cycle completion and institutional positioning continues to attract attention from both traders and long-term holders watching for the next major breakout.
