ETFs provide investors with exposure to a wide range of assets, including stocks, bonds, commodities, and cryptocurrencies, without requiring direct ownership. They offer liquidity, diversification, and lower expense ratios compared to mutual funds. ETFs enable passive investment strategies, allowing investors to track specific indices or sectors. Additionally, crypto ETFs have gained popularity, making it easier for traditional investors to gain exposure to digital assets without managing private keys or wallets. ETFs also provide tax advantages and lower trading costs.
