Reading ETH and BTC Option Flows as Relative Bullish Exposure

Article Deribit Insights
Read the original

Summary

The note interprets a set of reported crypto option trades near the end of 2023. It highlights buying in an ETH March $2,000–$3,000 call spread, ETH at-the-money options for December, and January and March $3,000 calls. At the same time, it reports selling of BTC December at-the-money options. The author reads this combination as bullish ETH exposure, with long basis, while BTC volatility demand eased as expectations for an imminent spot ETF diminished.

The note explains that an in-the-money to out-of-the-money call spread can serve as a delta substitute with a defined downside invalidation below $2,000. It also describes buying ETH gamma while selling BTC gamma, framing the positioning as a relative-volatility view. Open interest is said to indicate that the call spread was newly opened, and ETH implied volatility rose above 60%. These are interpretations of flow and positioning, not a complete trade specification or a verified forecast; the document supplies no subsequent outcome, valuation method, or risk limits.
