In ready player it costs 25 cents to enter the oasis , you have use real money for every thing else in fortnite you convert real money into v bucks but these have to be this way? I belong to couple facebook groups where you buy/sell cars from the game Forza horizon 4 or trade them with someone , fortnite there are underground communities where you can trade fortnite skins , v bucks . Instead of using real money to buy digital currency , why not upend the process when the metaverse arrives and takes the place of are regular lives nfts are something that can be used as form as currency , something you works towards or trade one thing for something else. Something my friend NolanIDI said NFTs are basically the building blocks of the metaverse. 

Currently there are metaverse games being built and you start out by buying your character (the nft art) then once the game is built the nft unlocks your access into it. There are also NFTs that give access to different AR experiences. 

The metaverse is being built as people buy NFTs just wonder companies like facebook or apple or gonna adapt this.
