Imagine wanting to invest in gold, but instead of buying a giant gold bar, you buy a small share of a giant gold bar hold by a company. An Ethereum ETF (Exchange Traded Fund) works similarly. It's an investment fund that tracks the price of Ethereum, allowing you to invest in it through a traditional stock exchange. This can be easier for some investors than buying and managing Ethereum directly. However, keep in mind that ETFs might come with fees and aren't exactly the same as owning Ethereum itself.
