I really hope I'm wrong but I think it got there by mistake.
If they supported cryptonight coins they would say so, like they announced it for eth and tokens.
And monero would be on it of course
Think no mistake there, Nova listed it purposely, they just not advertising it.
Anyway as I can see the wallet doen't synching anymore, pool not available, so don't know if it possible even if Nova really can list coin.
