I'm in no way trying to argue that the parent's classifications or conclusion make sense, just that it's not NTS because the parent isn't trying to make some universal assertions about crpyto in general and denying the exceptions but comment that the "scene" has changed drastically and the word cryptocurrency along with it.

NTS would be something like

* "All things people are calling cryptocurrencies made after 2015 are just finance-bro scams."

* "But what about TotallyLegitCoin, it's not a scam."

* "But that's not really a cryptocurrency."
