Stable income: Somewhat stable

Based on available information, cupping therapy as a side hustle can be considered Moderately Stable. While there is a decent baseline income potential, it may not always be reliable due to fluctuations in client demand and competition. Some therapists report consistent earnings, but others may experience variability in income. I'd rate it a 3 out of 5 because while it offers a steady income for many practitioners, there are still uncertainties that prevent it from being classified as a Stable source of income.
