Building a "real community" would guarantee the survival of this coin regardless of the activity of its main developer. It would be best to have some other devs joining it.
I think an independent community forum would be a good first step in this direction. I would offer myself for moderation and administrative tasks.
PS: Counterparty is not using PoB for network maintenance, Kore will use it for a different purpose (anonymous transactions, although I'm not sure how that will work), so SLM still seems the only one using it for distribution / network maintenance.
We need a response from the dev first. It's just my suggestion. Anyway thank for your support.
PS: I know about they use different kind of PoB but it shows that the PoB idea has potential.
