Create a digital wallet and use it to store your NFTs and crypto. This is the first step that needs to be taken in the process of earning money.
Next purchase the NFTs or the characters and items that are being sold as NFTs depending on need and rarity, if it is based on luck buying a substantial amount, this might not always be the case.
Download the game that utilises the NFTs that you have purchased and start using them in the game to level up.
The points that are earned can be different tokens that might have different values and can be converted to real-world money or can be used to upgrade the character.
Otherwise, the character can be traded or sold in the gaming NFT marketplace which depends on how rare they are or how their level is.
