I've seen a few bits about early NFTs re-selling for a stupid amount of money recently. To be honest I really don't know why, I like art and have bought paintings in the past to hang in my house but NFTs are different, I suppose you could print them out, frame them and hang them up, but so could anyone else. I understand that you're paying for the ownership and thus can trade them later so to me they seem to be speculative investments. Anyhow, I had some credits from unstoppable domains so bought two of their animals. - Who knows - they might turn out to be worth loads in future, they cost me nowt and helped me learn something new.
