If you only want to buy cryptocurrency as an investment, you may be able to do so through your brokerage. For example, Robinhood allows users to invest in bitcoin and other cryptocurrencies, although you cannot withdraw them from the platform for purchases. In addition, there are several crypto ETFs that provide exposure to the crypto asset class without requiring the investors to maintain their own wallets. For instance, as of May 2024, investors may choose to hold Bitcoin futures ETF shares. The SEC has also approved the listing and trading of Ether spot shares.
