Is a Website for an NFT Art Collection Important?
Yes, because a website serves as an "advertising brochure" for interested collectors to learn more about the NFT collection, including the artist, the producer, the process of creating the NFT art, the inspiration, etc.
This is actually a vital part of the marketing process for NFT collections minted on a blockchain such as Ethereum, Tezos, Solana, etc.
There are plenty of resources available on the internet to learn more about how to create a published website!
