Unfortunately for them, things didn't quite go as planned, with collectors balking at the high pricetag. Mints slowed to a crawl far before the 7,500 limit was reached, and the NFTs quickly began trading at a discount on secondary markets (meaning it was cheaper to buy a resold NFT than mint a new one).
Porsche decided to pump the brakes on the mint when fewer than 2,000 had sold. However, they botched that too — they announced they had stopped the mint before they actually did so, which caused the collection's secondary floor price to rise back above the mint price in anticipation of higher scarcity. Observant traders who noticed this were able to arbitrage the price difference, minting new NFTs and immediately flipping them for a profit on secondary markets.
NFT collectors criticized Porsche for appearing to try to jump into web3 without knowing the space, and asking for an exorbitant mint price without a clear plan.
