A cryptocurrency ETF is an investment fund listed on traditional stock exchanges that tracks the price of cryptocurrencies or related assets (such as futures contracts or mining company stocks). It provides investors with an easy way to access the cryptocurrency market without directly purchasing crypto assets, while also benefiting from professional custodial services and regulatory protections. Trading is similar to stocks, making it simple and efficient; however, investors should be aware of the high volatility of the cryptocurrency market and the potential impact of management fees on returns.
