Securities and Exchange Commission approves first Bitcoin exchange-traded fund

The U.S. Securities and Exchange Commission (SEC) has made it easier for investors to buy and sell cryptocurrencies by allowing companies to sell spot exchange-traded funds made up of the cryptocurrency Bitcoin, the same vehicle used to sell stocks and bonds. I decided to make it tradeable. The SEC approved applications for a Bitcoin ETF from 11 companies, including BlackRock, Fidelity Investments, and Grayscale Investments. The SEC previously refused to approve a Bitcoin ETF, saying it was too risky and vulnerable to fraud, making it unsafe for most investors. At a CFR event hosted by CFR President Mike Froman in December 2023, Gensler said that cryptocurrencies have “some similarities to the 1920s… Fraud and manipulation are rampant.” SEC Chairman Gary Gensler said the approval came not as a result of a change in the SEC's thinking about the safety of Bitcoin ETFs, but as a result of a court case won by Grayscale Investments in August 2023 that alleged that a spot Bitcoin ETF was similar to a Bitcoin ETF. Another type of cryptocurrency ETF that has already been approved is the Bitcoin Futures ETF. The SEC Twitter/X account announced the decision a day before the agency itself. But the SEC quickly removed the post and claimed the account had been hacked. The fake announcement caused the price of Bitcoin to skyrocket by $2,000.
