Did we buy them or did we get them free for holding EVMs and just have to pay gas...? I don't quite remember. Anyway I think the purpose of them is as an unlock for the premium features of Autominter (stuff like bulk airdrops and custom prices for different whitelists), so if you want to do an NFT project like the Pandas or Owls or whatever then they are probably pretty useful, but if you never intend to do anything like that then I'm not sure they have much reason to be valuable.
