Stable income: Somewhat stable

Based on research and online testimonials, the reliability of becoming a gaming coach as a full-time monthly income source varies. While some experienced coaches can earn consistently, many beginners face uncertainties and fluctuating income. Factors like the competitiveness of the market, client retention, and seasonality can all impact earnings. Therefore, if your best friend were to quit their job to pursue gaming coaching full-time, it would be considered a risk due to the potential income fluctuations and uncertainties. I'd rate it a 3 out of 5 because while there is a decent baseline potential income, it may not be as reliable as a traditional job paycheck.
