Today's largest block option for ETH: A certain boss bought a put option of 1500 at the end of April and sold a put option of 1900 at the same time, totaling 5000 ETH, earning a premium of 730000 yuan The boss probably holds a lot of spot money and feels that ETH has fallen to the bottom and is not likely to fall further. He earns profits by selling (put spread) options. A very robust strategy.
