What Is a Floor in an NFT Project?

The floor of an nft project is essentially the cheapest that you can buy said nft for. Usually projects have between five thousand and ten thousand total supply. The best ones will be the highest, and the worst per se will be at what is the floor - which is the cheapest you can get one for. Minting is getting it when it first comes out, so you're the first person to own it. And you have to pay gas to actually receive it from wherever a they put it out initially from.
