NFT = WTF?

I’m 45 and I work in IT.

WTF are these NFTs WWE are banging on about?

That is all.

Some kind of cybercurrency baloney I think.  Definitely a case where the kids on the Instabooks know way more than me about it.  Possibly related to Bad Bunny as well?  
Also kind of telling that this is the first e-mail even vaguely related to Wrestlemania that I've gotten since last night.  There really doesn't appear to have been much interest in the show.
