Ethereum breaks $4,400, with significant increases in implied volatility and Skew compared to last week, and market expectations for upward movement have noticeably risen.

In the options market, today's large call options trading reached $330 million, accounting for 24% of total trading volume, mainly consisting of medium to long-term call options, indicating that large investors are more optimistic about the sustainability of Ethereum's rise.

Bitcoin, on the other hand, is mainly focused on buying protective put options, and the market is beginning to diverge, with current trading activity primarily concentrated on Ethereum.

Options trading advice: Buy short-term ETH calls and BTC puts, and consider cross-asset straddle strategies.
