Monero does not have "a few" interesting, novel features, it is a completely new design and code base that is entirely distinct from bitcoin and all of the hundreds of clone shitcoins each of which have "a few" interesting, novel features (at best) added for polish.
The difference is one of kind, not degree.
No, there are not 20 other non-scam non-clone-with-polish altcoins. Maybe one or two.
I dunno, it just seems that if you were right and I was wrong the price would be faring better than it currently is.
It is a project that is alpha-level software, with no integrated GUI, no lightweight wallet or web wallet, high resource requirements to use the full wallet, zero applications or merchants, and it is still in the top 20 by market cap. That is very respectable.
Either "very respectable" or a sign that people will throw their money at just about anything. Time will tell.
