I am not certain that promoting the price of Peercoin would be in NuShareholders’ remit. Yes, it would be in their interests, as many/most NuShareholders are also Peercoiners, but they would not be wearing their NuShareholder hats.
As I see it, the price of peercoin does not affect peercoin’s relationship with NuShares. If the price of peercoin is low, dividends will buy more of them; if the price is high, dividends will buy fewer. So, price is a moot point.
However, I think there is a valid interest in NuShareholders doing what they can to support Peercoin as a stable and secure crypto, as this ensures a means through which dividends can be reliably paid (and stored). Of course, by supporting peercoin in this organic way, the peercoin price will probably rise anyway
I look forward with interest to buzzdave’s proposal
