PANews reported on April 30 that according to The Block, the volatility of Bitcoin and Ethereum fell to a 7-day low this week, and the open interest (OI) of BTC and ETH options increased by about US$1 billion and US$150 million respectively. Data from the Derive platform showed that 73% of the premium in BTC options was used to buy call options, and the proportion of ETH was as high as 81.8%. The number of call options was 3 times and 4 times that of put options, respectively, indicating a strong bullish sentiment. However, data from mainstream platforms such as Deribit showed that the market as a whole was still relatively cautious. Analysts said that even in the worst case scenario, BTC and ETH are expected to maintain the current range in May.
