An anonymous nonfungible token (NFT) collector spent 204 Ether (ETH) worth roughly $488,800 (at the time of writing, considerably more when it occurred) on gas fees to mint 1,000 Tubby Cats NFTs.
In total, the Tubby Cats enthusiast clearly had some capital to burn as they spent more than $720,000 on minting the NFTs including gas fees, according to the Etherscan transaction history.
