One of the biggest global exchanges, CME Group launched Bitcoin futures trading on Dec. 17, following the launch of BTC futures by the Chicago Board Options Exchange (CBOE), the largest U.S. options exchange, on Dec. 10.

In May, the Federal Reserve Bank of San Francisco published an Economic Letter alleging that the Bitcoin price decline following the $20,000 all-time high in December was the result of the introduction of Bitcoin futures. The Fed claimed that “the rapid run-up and subsequent fall in the price” after the launch of BTC futures trading “does not appear to be a coincidence.”

Earlier this month, the largest exchange-traded fund (ETF) supplier in the world BlackRock, announced it is forming a working group to consider whether the company should invest in Bitcoin futures. Considering Bitcoin futures represents a U-turn for BlackRock, which has previously been critical of cryptocurrencies.
