NFTs being a fraud (or a 'scam' - don't like that word, overused) ... I mean that's not dependent on a particular cryptocurrency :) It's just a dumb idea that some people like for whatever reason. There's a ton of that rubbish on bitcoin (really, it started on bitcoin, way back in 2014).

I'm glad you feel that way about LN now and how it has developed. It's still not quite there if we want something with decent privacy and mass market usability, but it's a very practical, real technology. I use it every day.
