Macro analyst Adam from Greeks.live posted on the X platform, stating that the ETH ETF will be launched next Tuesday. Stimulated by this positive news, ETH rose by 8%, significantly driving up the entire cryptocurrency market. The sharp increase in coin prices also drove up IVs across all terms synchronously. The implied volatility of BTC even exceeded that of ETH, but both are still relatively low. This month we have mentioned multiple times in our tweets that good news about ETH would stimulate the market; a low IV situation is very suitable for buyers as option IV remains relatively low and buyer's cost-effectiveness is still high. Today, several end-of-day bullish options increased by more than 1000%. Most transactions throughout the day were mainly proactive purchases of bullish options, accounting for more than half of trading volume.
It should be noted that end-of-day options, also known as "doomsday wheel" options refer to the last few trading days when an option contract is about to expire.
