You all seem to have addressed most points I would also make. I have little faith in Bitcoin’s long-term future because of its sustainability issues and/with centralising mining (=security). Radically changing Bitcoin at this point appears unfeasible, and so Peercoin is a prime and only candidate I see among the Bitcoin-based cryptocoins that tries only to do the backbone role. I don’t have much insight in Ethereum, Monero, Nxt, etc., though.
Talking about backbone has always seemed vague to me. To completely break free from the current financial systems I think there has to be some sort of asset with free value, and Peercoin seems to be one with healthy distribution and life expectancy. The way Peercoin might sustain itself should be valuable as a central ledger for settlements.
NuBits is a currency, and we’re having this conversation because we can’t pipe revenue into Nu itself.
If distributing dividends in Bitcoin can earn Nu publicity, I’m not opposed to it. We don’t have to distribute in Bitcoin forever. As much as I’d like Nu to generate upward pressure in Peercoin, a greater Nu would have even more power to do that later. Plus—as you suggest—we could do both partially.
