Passive income: NO

Selling Pokémon GO accounts has the potential to generate passive income, but achieving this level typically requires significant setup and ongoing management. The setup costs range from $100 to $500 for acquiring high-level accounts or investing in resources to level up accounts efficiently. To make this hustle passive, you would need to automate the account leveling process by using bots or hiring others to play and level up the accounts for you. However, this practice goes against Pokémon GO's terms of service and could result in bans. While some individuals may reach a level of passive income through this hustle, it is more common for this business to require ongoing effort to maintain profitability. Many accounts are also subject to being banned by the game developers, leading to potential loss of income. Overall, while passive income is possible in this niche, it is not the norm for most participants.
