On May 31, eToro senior market analyst Mati Greenspan pointed out in a blog post that the CME bitcoin futures contract in May will expire at 4 pm London time today, and the transaction volume has now exceeded $8 billion, which will become a history. The largest transaction volume since. CME traders may hedge their positions by holding real Bitcoin elsewhere. In addition, although the contract expires today, the final settlement will take place on Monday, and the trader will choose to choose cash settlement or to continue the contract. This weekend, futures contract holders have the opportunity to benefit from price changes during the weekend. Therefore, it is the hedge position that may affect the price of Bitcoin this weekend. Greenspan believes that Bitcoin may enter a turbulent weekend.
