Bitcoin has surged 6.8% to hit a four-week high of $72,951 this Thursday, March 5, 2026. The rally was primarily sparked by reports of secret negotiations between Iran and the U.S., which led to a broad "risk-on" shift across global assets. A significant derivatives short squeeze has further accelerated the momentum, with market analysts now eyeing the $76,380 resistance level as institutional ETF inflows show signs of a major resurgence.
