Stable income: Somewhat stable

Selling on Mercari can provide a moderately stable income source for most people who try it. Based on online research and my own observations, while there is a decent baseline for earnings, income can be unpredictable at times. Some sellers experience similar monthly revenues, while others face fluctuations. I'd rate it a 2 out of 3 because there is potential for consistent income, but it's not as reliable as a steady job paycheck.
