How to Buy NFT on OpenSea (OpenSea NFTs Guide 2025)

An NFT (non-fungible token) is a unique digital ID that lives on a blockchain and proves who owns and created digital assets. These assets can be anything from artwork and music to videos and photos. When we say "non-fungible," we mean each token is unique, and you can't swap it for another one. This is unlike cryptocurrencies or regular money, where you can trade one dollar for another.

The blockchain keeps track of who owns each NFT through digital signatures, and this record can't be changed. It shows every time someone buys or sells an NFT. While anyone can copy the digital files themselves, the blockchain proves who owns the original. Plus, artists, creators, and collectors don't need to know how to code to make NFTs - it's pretty straightforward.

Creators make (or "mint") NFTs by generating a unique token on a blockchain. Think of minting as the birth of a digital collectible - it's when your digital item officially becomes an NFT and gets recorded on the blockchain.

Here's what actually goes into the blockchain during minting: Sometimes it's the whole piece of digital art and all its details (what we call "on-chain" storage), but often it's just a link that points to where the art is kept elsewhere, usually using something called IPFS (InterPlanetary File System).

Either way, minting is turning your digital creation into an official NFT that people can buy and sell.

Yes, you can resell an NFT. Here's how it works:

Once you own an NFT, you can list it for sale on various NFT marketplaces like OpenSea, Rarible, or other platforms built on the relevant blockchain. When you sell your NFT, the blockchain records the transfer of ownership to the new buyer, just like it did when you first bought it. A few key things to know about reselling NFTs:

• Some NFTs include "royalties" programmed into their smart contracts, meaning the original creator automatically gets a percentage of each resale.
• You'll typically need to pay transaction fees (called "gas fees" on Ethereum) to list and sell your NFT.
• The value of your NFT can go up or down based on market demand - just like traditional collectibles, there's no guarantee you'll be able to sell it for more than you paid.
• You can usually set your own price and choose between different types of sales, like fixed price listings or auctions.

Keep in mind that market conditions heavily influence whether you can successfully resell an NFT and at what price.
