Jordan Belfort, known as 'The Wolf of Wall Street,' advised against following investing experts, including Jim Cramer, and picking individual stocks. He criticized active management due to fees, commissions, and tax liabilities. Instead, Belfort recommended buying and holding high-quality stocks, reinvesting dividends, and compounding growth. He suggested ETFs like SPDR S&P 500 (NYSE:SPY) for consistent profitability and stressed the importance of passive investing and diversification with bond funds.
