Mars Finance News, Greeks.live analyst Adam released a cryptocurrency options block trade daily report, stating that the largest option block over the weekend was 250 4000 Put options expiring on April 1st and 250 80000 Put options expiring on April 1st. Strategic logic: Betting that market weakness after March delivery will continue to decline, with naked put option operations increasing before delivery, directly adding 500 contracts over the weekend, spending nearly $300,000 in premiums. Adam suggested that whales are betting on a downturn without protection, which is a strong bearish signal, and market downside risks should be closely monitored. Weekend block trades were limited, with other block trades mainly focusing on position adjustments after monthly delivery. Calendar spreads and vertical spreads were the most popular combinations. Overall, the market is characterized by negative Delta and positive Theta, with a gradual decline being the mainstream view, and ETH showing a slightly stronger bearish tendency.
