Odaily Planet Daily News: Amid renewed optimism about the approval of an Ethereum spot ETF, an analyst said that Ethereum call options of all expiration dates are now more expensive than put options, indicating bullish market sentiment. Deribit CEO Luuk Strijers said in an email: "The skew of put and call options for all expiration dates is negative and has increased further after the end of June, which is a fairly bullish signal-the basis spread has also increased to an annualized level of about 14%, another bullish indicator." Its analysis shows that traders are willing to pay higher fees for call options, especially for options with expiration dates at the end of June and beyond. This may be a bullish market indicator because it shows that traders expect Ethereum prices to rise in the future. Therefore, they are less willing to pay a higher premium for downside protection on put options. (The Block)
