NFT is getting hot because of the DAPPs and the demand surrounding its application. NFT brings artistic and applied value in play to earn games.
I think NFT is just a trend in crypto. We cannot know where crypto will be applied in the future because crypto can be applied to many areas of the economy, social life...
Currently, NFT and the game 'play to earn' are the closest things to life.
In addition to the payment function, NFT and its related applications are useful. We have the game (play to earn), music, pictures, videos... people can make money from creating content from them. Especially during the pandemic, people have more free time, they play games, participate in art creation. CZ-CEO of Binance is talking about Metaverse, which will be the mainstream of crypto future.
