A Bitcoin ETF (exchange-traded fund) lets investors get exposure to Bitcoin's price through a regular brokerage account, without holding the coins themselves. For many traditional investors, that's far simpler than setting up a wallet.
What it means for you: ETFs have brought big, mainstream money into Bitcoin and made it easier for institutions to participate. But an ETF is not the same as owning Bitcoin — you don't hold the keys, you can't move or spend the coins, and you pay fund fees.
If your goal is simple price exposure inside a brokerage, an ETF can fit. If you want to actually own and control Bitcoin, buying on an exchange and self-custody is the path. This is educational information, not financial advice.
