Many friends have recently asked what exactly an ETF is. To put it simply, an ETF is an Exchange-Traded Fund that bundles a basket of assets into a single product, so you don't have to buy each one individually.

In the crypto world, for example, a Bitcoin ETF tracks the BTC price. Buying this fund is equivalent to holding Bitcoin exposure, without the need to manage private keys yourself. After the launch of spot ETFs, many traditional investors have entered the crypto market through this channel.

The advantages are obvious: risk diversification, simple operation, and flexible entry and exit. For beginners, there's no need to bother with wallets and exchange accounts; you can participate in crypto trading directly through a broker. Of course, there are also disadvantages, such as losing the feeling of truly holding digital assets and paying management fees.

Overall, ETFs make crypto investing more accessible and regulated, which is the main reason they've become popular in recent years.
