Cash dividends can provide investors with continuous cash flow. In the volatile market, the realized income can be "pocketed" in time, which is suitable for investors with special cash flow needs.
Dividend reinvestment allows investors to enjoy compound interest income and pursue higher income through long-term investment, which is suitable for investors with long-term investment plans. If the market is in an upward trend for a long time, the income from dividend reinvestment will be higher than that from cash dividend.
