Today, an interesting event occurred in the cryptocurrency market. On the Deribit platform, a user demonstrated a deep understanding of the Ethereum options market by making a large-scale trade. This user sold a batch of bullish and bearish options expiring at the end of October, with a specific strike price of $3,400, involving a total of 500 Ethereum (ETH). This series of operations earned the user $394,000. Analysts generally believe that this transaction reflects investors' predictions about market volatility, expecting Ethereum's price to fluctuate between $2,750 and $4,450. From this perspective, the investor may have adopted a short-volatility strategy, aiming to achieve a target yield of up to 24.45% in the currency by locking in profits within the profit range. This not only reflects the investor's deep understanding of the Ethereum market but also their precise judgment of market trends.
