PANews reported on November 23 that Jeff Park, Chief Investment Officer of Bitcoin treasury firm ProCap and advisor at Bitwise, analyzed that Bitcoin's implied volatility has never exceeded 80% since the FTX crash. The closest it came was in March of last year, when the spot Bitcoin ETF experienced continuous inflows, but now the indicator has returned to pre-ETF listing levels. According to data disclosed by Jeff Park, among Bitcoin options expiring on December 26, the $85,000 put option open interest (OI) is the largest, approximately $1 billion, higher than the $125,000 call options ($620 million), $140,000 call options ($950 million), and $200,000 call options ($720 million).
