Before focusing on funds, make sure you understand the rules. This time, let's talk about non-fungible tokens (NFTs).
Every fungible token is identical—for example, one ETH can be exchanged for another. But every NFT is unique.
Before listing an NFT on a marketplace, check what you're authorizing. Granting approval for an entire collection at once may allow the other party to transfer all your NFTs in that collection.
On Ethereum, minting and trading NFTs requires $ETH to pay gas.
