Stable income: Somewhat stable

Selling League of Legends accounts can provide a monthly income ranging from $100 to $500, depending on the time and effort invested. While some individuals report consistent earnings from this side hustle, many factors can lead to fluctuations in income, such as market demand, competition, and account quality. Based on online experiences and observations, this opportunity falls under the 'Moderately Stable' category, as there is a decent baseline of income potential, but reliability can vary. If your best friend were to pursue this full-time, I would say it's a risk due to the unpredictable nature of the market. Overall, I'd rate it a 3 out of 5 because while it can offer a reliable income stream at times, the variability in earnings makes it less secure than a traditional job.
