Bitcoin futures unpositioned squaring contracts increased by more than 20,000 BTC in a single day, the largest one-day gain since June 3. The total number of bitcoin unpositioned squaring contracts has reached $42.60 billion. High position squaring contracts can lead to increased volatility, especially when the contract is about to expire. Traders may rush to position squaring, rollover or adjust positions, which can lead to large price swings.
