Which crypto ETFs are currently available and what are the main differences between them?

Crypto ETFs (Exchange-Traded Funds) allow investors to gain cryptocurrency exposure through traditional brokerage accounts. Major Bitcoin ETFs include the Grayscale Bitcoin Trust and spot Bitcoin ETFs approved in 2024, which directly hold Bitcoin. Ethereum has similar options like Grayscale Ethereum Trust. Key differences include: spot ETFs hold actual crypto, while some hold Bitcoin futures contracts; expense ratios vary (typically 0.2-2.5% annually); and some offer leveraged exposure (2-3x multipliers) for advanced traders. Spot ETFs are generally simpler for beginners, providing direct asset exposure without futures complexity. Regulatory status differs by country—the US approved spot Bitcoin and Ethereum ETFs in 2024, while other regions have different rules. Consider your investment goals, risk tolerance, and fees when choosing.
