The Metaverse Glossary


  • Ape in

    Ape In is a term to describe people who rush into purchasing a new NFT or currency without conducting thorough research or study. It all started with the ‘apes together, strong’ meme. However, it is always advisable not to ‘ape in’ to any projects without first conducting a thorough study and knowledge of what you’re purchasing.
