A bitcoin ETF is one that mimics the price of the most popular digital currency in the world. This allows investors to buy into the ETF without going through the complicated process of trading bitcoin itself. Moreover, because holders of the ETF won't be directly invested in bitcoin itself, they will not have to worry about the complex storage and security procedures required of cryptocurrency investors.
There is another crucial benefit to focusing on a bitcoin ETF rather than on bitcoin itself. Because the ETF is an investment vehicle, investors would be able to short sell shares of the ETF if they believe that the price of bitcoin will go down in the future. This is not something that can be done in the traditional cryptocurrency market
