【BTC and ETH Implied Volatility Declines, Traders Flood into Options Market Seeking Leverage】On April 30, news from The Block reported that the volatility of Bitcoin and Ethereum has dropped to a 7-day low this week, with BTC and ETH options open interest (OI) increasing by approximately $1 billion and $150 million respectively. Data from the Derive platform shows that 73% of the premiums in BTC options are used to buy call options, while the proportion for ETH is as high as 81.8%. The number of call options is 3 times and 4 times that of put options respectively, indicating strong bullish sentiment. However, data from mainstream platforms like Deribit shows that the overall market remains relatively cautious. Analysts suggest that even in the worst-case scenario, BTC and ETH are expected to maintain their current range in May.
