According to AMBCrypto reports, institutional data can clearly observe the recent reversal of the bear market trend in the BTC market. Skew data shows that on February 18, CME's BTC futures trading volume reached a record of 1.1 billion U.S. dollars since its peak in 2019. However, the situation changed within a few days, and the daily trading volume of BTC futures once dropped to $ 118 million. As of press time, the daily trading volume of BTC futures is slightly less than 300 million US dollars. Skew market data also shows that the open interest in CME BTC futures has fallen from $ 338 million on February 14 to $ 210 million on February 18. Open interest is still higher than the October-December 2019 average, but the sharp drop in the past two weeks may be a worrying sign.
