[BIT: Bitcoin 7-Day Implied Volatility Drops to 25%, Near Historical Lows] According to Deep Tide TechFlow on August 17, analysis from BIT's official Chinese account (@BITofficial_CN) indicates that Bitcoin's 7-day implied volatility has fallen below the 30% threshold, dropping to 25%, similar to the low-volatility period in the summer of 2023. Against the backdrop of relatively low option prices, analysts suggest that investors consider a 'spot replacement strategy'—selling a portion of Bitcoin spot holdings and replacing them with bull call spreads or directly purchasing call options. This approach allows investors to retain upside exposure while limiting maximum losses to the option premium if prices continue to decline. The freed-up capital can also be used for other yield-generating opportunities.
