the floor refers to the price of the cheapest nft for sale in a series. The floor, ideally, goes up in value post-mint, due to the limited supply available. But if desire if less than expected, which is much more common than not, the floor can somehow be below the cost of mint, even during the minting process.
Yo frens, I hate to sound this way, but this project isn't going to make it, the floot isn't moving.
Whoa mate, we're not even done minting, their are still rare ones, and the promotions have just started. The floor can't go up while minting is live anyways!
