Bitcoin Option Flows and the Reshaping of Upside Exposure
Summary
This market commentary tracks Bitcoin options activity around a price decline and rebound. It describes traders selling October and November 70,000 calls and buying October puts with strikes from 57,000 to 60,000 amid speculation about US government selling. After Bitcoin’s decline halted near 59,000 and it rebounded above 62,000, the puts were unwound and call buying appeared across October, November, and December expiries.
The note also highlights a shift in longer-dated upside exposure: December 90,000 calls were moved toward 80,000 calls, while March 100,000 calls were repeatedly sold. It reports that implied volatility rose alongside spot, with the 30-day measure increasing from 52% to 58%, and that the ETH/BTC volatility premium narrowed. These are observations about specific flows and market conditions, not a tested trading strategy. The brief account gives no full trade context, methodology, or performance evidence, and its attribution of the earlier selling to government activity is described as speculation.
