Greeks.live macro researcher Adam Yu X published an analysis of recent weekend options block trades:
Last weekend, block options transactions were concentrated on BTC, mainly calendar spreads, and transactions were not active, which was normal weekend trading volume.
There was a very strange calendar spread, the IV of buying 12OCT24-60000-C was as high as 495%, which means that the option worth 0.004 BTC was bought at a price of 0.0434 BTC per piece, and 100 BTC was bought.
The analysis said that the user may have made a mistake (clicked the wrong decimal point), and the counterparty of this transaction directly earned nearly 4 BTC.
