Personally I think the only one that really makes sense is Monero - and thats only becuse it has a solid use case (and is being used a TON). And interestingly enough its not really used as a speculative currency (the price is not nearly as volatile - meaning you will probably never get rich form it either).

NFT's I think potentially had SOME initial interesting tech (mainly the early talk about being able to track photo copyright for photographers for example) but quickly evolved into the crypto BS investment crap.
