MVI is the token of the MetaverseIndex, which is an index that tracks a set of tokens from different virtual spaces and metaverses. Its operation is very similar to stock market indexes such as the Nasdaq or the S&P500.
Metaverse Index sets certain parameters to determine which tokens make it up: it must be available on the Ethereum blockchain; that it is in certain Coingecko categories such as NFT, Entertainment, VR, AR, Music, among others; that the market cap exceeds $50M; and more.
The $MVI token can be obtained from Index Coop, UniSwap, Metcha and BitGo, among others. You can become an MVI LP through UniSwap or SushiSwap. However, there is no way to stake the token yet.
