If you can “buy” nft’s then Idk why you can’t buy something with less value.
I’ll tell you why: because there’s nothing with less value than an nft.
I just remember the day, as a software dev with a solid understanding of Blockchain, my older dev neighbor started explaining how NFTs worked
I thought he was confused or stupid or something.
“Wait, so like you have these super rare images, proof you own it on a Blockchain, and a link to the place they’re all publicly hosted?”
Him: “Yep”
“And the only use for these right now is as a profile picture?”
Him: Shrug, “yeah, people use them for discord and stuff”
“But… Couldn’t you just download the image and use it anyways?”
Him: “Yeah, it’s all publicly hosted”
And it was about then my brain locked up. I did multiple hours of research later, sure I had to be missing something
You can buy medical debt, that has lots negative of value to the indebted.
