  2. Users and Players are informed that, in the context of the Marketplace, the Company acts solely as an intermediary, providing a digital infrastructure to facilitate transactions related to NFTs.
  3. Due to the peer-to-peer nature of the Marketplace, these T&Cs do not govern the relationship, of any kind, between sellers and buyers on the Marketplace.

  1. NFTs act as certificates of digital ownership of files and other associated data. The rarity, ownership and traceability of an NFT is guaranteed by the token, which is different from the file itself.

  3. Therefore, although the risk of loss does not exceed the amount invested, Users agree not to invest funds that they cannot afford to lose. Furthermore, Users acknowledge that past performance is not an indication of future performance, which may vary both upwards and downwards.
