What is the difference between a spot ETF and a futures ETF?

A spot ETF holds actual cryptocurrency assets, so when you buy shares, you own real Bitcoin or Ethereum stored securely. A futures ETF doesn't hold the actual crypto—instead, it tracks price movements through futures contracts, which are agreements to buy or sell at a future date. Spot ETFs are generally simpler for beginners since you own the real asset. Futures ETFs can be more complex and may involve different tax treatment. Spot ETFs typically have lower fees and are considered less risky since there's no contract expiration date. Both allow investors to gain cryptocurrency exposure without directly managing a crypto wallet, making them accessible through traditional brokerage accounts.
