The NFT is not a random non-fungible token but the official token of the YouTuber since he supports the Wallem project in which he is one of the skins available for players.
In fact, all the characters in the Wallem game will also be NFTs available for purchase on Opensea or Rarible.
The reward model of the project is very interesting and changes the paradigm of the monetization of blockchain-based games.
How do Pteria’s NFTs work
Pteria is a DAO that has entrusted Wallem with part of its PTERIA tokens (to be precise 2.5 million out of a total supply of 21 million).
Wallem is a mobile game for iOS and Android, similar to Pokémon GO but for capturing crypto and other prizes. The player, using their avatar, moves around on an augmented reality 3D map to capture various rewards, including PTERIA tokens.
Each of the game’s avatars has their own corresponding NFT, so those who buy the non-fungible token will be entitled to 10% of all the rewards the player collects in the app, plus 100% of the PTE spent in the app to buy the corresponding avatar.
This applies in the case of the PewDiePie NFT, which is why it was sold at such a high price given the passive income it could generate over time.
Furthermore, the 57.75 ETH cashed by the Pteria DAO will all be converted to PTE using Uniswap or Balancer where the token is listed and all these PTE will be burned.
