Is the 21st Bitcoin’s Unlucky Date? Its Latest Breakout Just Fell Apart

On October 21, Bitcoin’s rally reversed and the largest cryptocurrency fell below $83,000 to trade at $82,486, down 0.28% over 24 hours. Santiment data showed open interest near $23.4 billion and climbing before the reversal, and the firm warned that fast leverage build-ups can deepen liquidation cascades. CoinGlass data showed longs accounted for $91.19 million of $95.22 million in crypto liquidations over four hours, while trader Ted Pillows said the breakout had failed and late longs were flushed overnight as funding rates fell near zero. Analyst Benjamin Cowen said the 21st marked local tops in July and September, making October a test of whether that pattern would repeat.
