ETF
An ETF, or exchange-traded fund, is an investment fund whose shares trade on a stock exchange like an ordinary stock, giving investors exposure to the fund's underlying assets without holding those assets directly. In crypto, ETFs matter because they let people invest in bitcoin or other digital assets through a standard brokerage or retirement account, with no wallets, private keys, or crypto exchanges involved.
Crypto ETFs come in different designs. A spot ETF holds the actual cryptocurrency in custody, so its share price tracks the market price of the coins in the fund. A futures-based ETF instead holds regulated futures contracts, which can drift from the spot price over time due to the cost of rolling contracts. For example, an investor who wants bitcoin exposure in a retirement account can buy shares of a spot bitcoin ETF through their broker; the fund's custodian holds the bitcoin, and the investor simply owns fund shares.
A common misconception is that owning a crypto ETF is the same as owning crypto; ETF holders cannot withdraw coins, use them on-chain, or self-custody them, and they pay an annual management fee for the convenience. Availability differs by jurisdiction, as regulators approve such products on their own timelines. ETFs have been significant for the industry because they opened crypto exposure to institutions and advisers who are restricted to regulated, exchange-listed securities.
