For years, bitcoin supporters in the United States have been asking for a crypto ETF, but the SEC has yet to approve one. Back in 2013, the Winklevoss brothers' crypto exchange Gemini filed for the first Bitcoin-based exchange traded fund, and Brazil and Canada just received their first BitcoinETFs. The SEC is also considering proposals from Fidelity and Van Eck, and will make a decision by the end of the month.
