There is a big demand in NFT and many developers of the games use NFT to attract their attention to games.
The opportunity to earn money attracts a lot of gamers to NFT and allows people to earn money by playing.
NFT allows earning money for many people. Many people create NFT to earn money. Other people earn money on collecting, buying and selling NFT.
A lot of people buy NFT and use them for investment purposes. It is possible to make even more money on NFT than on altcoins.
That is why there is so big demand in NFT.
Bigger risk playing with NFT as collected or make NFT as investment assets, I think many people try to buy it just hype promo and we don't know later what happen with NFT still exist or not. How ever play to earn game right now many scam and just AXIE as play to earn game still paid but with lower value, all player just earn about 200 slp under 4$ and waste almost 3 until four hours to playing advantage and arena game. I miss from all NFT game and better investing with coin only than have buy NFT as collected or investment assets for the future.
