Passive income: NO

Earning passive income solely from running an NFT Marketplace Consulting side hustle is challenging and not very likely for most individuals starting today. While it is possible to automate certain aspects of the consulting business and potentially outsource tasks, achieving true passive income where minimal effort is required on an ongoing basis is rare. Most people in this field often find themselves continuously engaging with clients, staying updated on NFT trends, and actively marketing their services to maintain a consistent income stream. While there may be a few outliers who have successfully scaled their consulting business to a more passive level, they are not the norm. It's important to set realistic expectations and understand that significant time and effort are typically required to sustain and grow an NFT Marketplace Consulting side hustle. Costs range from $100 to $500 for basic setup and marketing materials.
