Total cryptocurrency market capitalization surpassed $3 trillion on Sept. 22, 2026, as Bitcoin approached $87,000 amid nearly $1 billion of inflows into U.S. spot Bitcoin exchange-traded funds and a U.S. Treasury move to expand long-dated bond buybacks. Bitcoin reached an intraday high of $87,395 on Sept. 21 after reclaiming key moving averages and triggering substantial short liquidations. The rally also brought Bitcoin into a $83,000-$86,000 supply zone where Glassnode estimates 1.07 million BTC was acquired, primarily by long-term holders, creating a potential source of selling as investors return toward breakeven. The same area marks the aggregate breakeven level for the Bitcoin ETF complex after 228 consecutive sessions below it and roughly $18 billion in unrealized losses at its February low. Glassnode reported muted selling indicators despite the price recovery, while Nansen analyst Nicolai Sondergaard said sustained spot and ETF inflows, rather than derivatives activity alone, would be needed for the advance to hold. A durable move above $86,000 would place Bitcoin through a dense modeled short-liquidation zone, with $87,000, $90,000 and about $92,000 identified as subsequent levels to watch.
