币界网报道：Ethereum is approaching the $2,800 mark as call options activity surges, signaling bullish sentiment among traders. Data shows a 27% increase in open interest for ETH call options, particularly at the $2,800 strike price, indicating strong expectations for further price appreciation. Analysts attribute this optimism to improving market conditions, including potential ETF approvals and growing institutional interest in Ethereum-based products. The surge in derivatives activity coincides with ETH's recent price rebound, which has seen the cryptocurrency climb over 15% in the past week. Market observers note that this options activity often precedes significant price movements, suggesting traders are positioning for potential upside. The increased demand for calls comes as Ethereum network activity remains robust, with decentralized applications and layer-2 solutions continuing to attract users and capital.
