Exchange #Bitcoin reserves dropped to ~2.75M BTC, the lowest since 2018. 33,000+ $BTC left exchanges in the past 30 days alone, with outflows accelerating in March. #ETFs, corporate treasuries, and self-custody are draining exchange liquidity. Meanwhile, 95%+ of all #Bitcoin is already mined. $BTC is still consolidating around $70K as available supply quietly thins out. Historically, this kind of structural squeeze hasn't stayed silent for long.
