Over 13,800 BTC left Binance in a single day, the largest outflow since 2023, while the exchange's reported reserves dropped from approximately 705,000 to 685,000 BTC in four days. This could be accumulation/self-custody, reducing the supply immediately available for sale, but an exchange outflow alone doesn't necessarily prove that those coins are being held long-term. I would monitor it in conjunction with ETF flows and support around $82,000 before interpreting it as a new market phase.
