On April 30, according to The Block, the volatility of Bitcoin and Ethereum dropped to a 7th low this week, and open interest (OI) in BTC and ETH options increased by approximately US$1 billion and US$150 million respectively. Derive platform data shows that a 73% premium on BTC options is used to buy call options, and the ETH ratio is as high as 81.8%. The number of call options is 3 times and 4 times that of bearish ones respectively, indicating a strong long sentiment. However, data from mainstream platforms such as Deribit shows that the overall market is still relatively cautious. Analysts said that even in the worst case scenario, BTC and ETH are expected to maintain the current range in May.
