According to trevor.btc on Twitter, THE DOUGHJO project is offering a 24-hour free mint for Unlisted Ninja NFT holders, with an official Parent Inscription linking to new art traits. The minting is accessible via the Pizza Ninjas Discord. This limited-time offer could drive short-term trading volume and increased demand for Unlisted Ninja NFTs, potentially impacting their floor price and liquidity on secondary marketplaces. NFT traders should monitor activity and liquidity as the expansion of official art traits may influence both collector and investor interest in related Bitcoin Ordinals and NFT assets (source: trevor.btc on Twitter, June 10, 2025).
