币界网报道:Crypto journalist Zack Guzmán reportedly made a 20x profit by selling a Tequila-themed NFT he received for free at a 2021 event. The NFT, part of a limited collection by 818 Tequila, was initially valued at $500 but sold for $10,000 in a recent OpenSea auction. Guzmán highlighted the unpredictable nature of NFT valuations, noting that the same collection includes unsold pieces listed at just 0.01 ETH ($18). The sale underscores the volatile and speculative market for celebrity or brand-linked NFTs, where rarity and hype can dramatically influence prices despite fluctuating demand.
