It's the weekend market time again. Today is still the expiration date for the July monthly options, with a large number of options facing settlement and rollover, which generally amplifies market volatility.

From the perspective of implied volatility (IV), Bitcoin's IV shows signs of increasing, while the risk-reward (RR) is negative, indicating bearish sentiment among traders, with put options being more expensive.

Ethereum's IV is different; it shows an overall trend of decreasing volatility, but the RR is positive, proving that bullish sentiment still prevails, although traders have psychological expectations for future sideways movement.

From gamma exposure (ex), Bitcoin's negative gamma area is concentrated and far exceeds the positive gamma area. In the future price range of 115 to 120K, volatility is expected to increase.

ETH's gamma exposure shows a reduction in the negative gamma area, while the positive gamma area is expanding and shows a growth trend.

This indicates that the selling power of Ethereum is strengthening, and it may face resistance in the short term.

In summary, it is still recommended to buy Bitcoin on dips, taking advantage of high volatility to achieve low buying and high selling trades.

For ETH, it is more advisable to act as a seller to gain from decreasing volatility. Strategies like double selling at the end of the month or weekly double selling are relatively cost-effective methods.

Wishing everyone to be friends of time and prosper together~
