Stable income: Somewhat stable

Selling NFTs can be a volatile source of income for most individuals. While some people do achieve consistent earnings, the market is highly unpredictable with significant fluctuations in demand and value. Many factors influence NFT sales, including trends, marketing efforts, and the overall crypto market. Thus, relying solely on selling NFTs for a stable monthly income can be risky and challenging. I'd rate it a 2 out of 5 because while some individuals may see success, the overall instability and uncertainty make it a risky choice for a reliable income.
