The possible approval of a spot Bitcoin exchange-traded fund (ETF) in the United States is anticipated to have a significant impact on the crypto market, particularly on companies like Coinbase and MicroStrategy. Analysts predict that the U.S. Securities and Exchange Commission (SEC) will approve the first spot Bitcoin ETF by January 9 or 10, potentially catalyzing the next crypto bull market and increasing crypto adoption. If approved, the ETF could open the gates for traditional investors to enter the crypto market, putting negative pressure on Bitcoin proxies like MicroStrategy. This approval could also affect MicroStrategy's stock premium related to the Bitcoin it holds. Additionally, the approval of a spot Bitcoin ETF is expected to boost crypto adoption and potentially translate into buying pressure for MicroStrategy stock. Meanwhile, American cryptocurrency exchange Coinbase has positioned itself as the custodial service to trust for the Bitcoin held by the ETF funds, aiming to gain more revenue and generate more demand from traditional investment sector players.
