Before you buy your first NFT, read the total cost — not just the price tag. Most sales carry three separate costs: the marketplace fee (the platform's cut), creator royalties on resale (which some marketplaces enforce, some make optional, and some ignore), and gas for the on-chain transfer. On a cheap item at a busy moment, gas alone can cost more than the NFT itself. I wrote a beginner guide to how NFT marketplaces actually work, including the fee split and how to avoid fake collections: https://zimbuck.com/blogs/1822/What-Is-an-NFT-Marketplace-How-NFT-Marketplaces-Work-Fees
