Before you set the fixed price or auction of your NFTs, research other similar projects to see what their floor prices are, connect with your community online, get a sense of the appetite for what you’re selling, and use other analytics tools to help guide you to finding the right price. OpenSea will also prompt you via pop up asking you to confirm if you create a listing far below the floor price. This can help you catch any misplaced decimals or an extra 0 you might have missed!
