Share buybacks are the only reason to own NSR since JordanLee (lead developer, AKA Phoenix) has a veto-proof majority of the network and your vote does not matter anymore. There is practically no reason to speculate on NSR going up unless there is a sign of a buyback in sight (there is not). A share buy back is when Jordan thinks the NuBit peg is strong enough and he decides to spend the NBT buy side BTC in the NSR market. Historically these are followed by an epic NSR crash, probably because the NuBit peg was manipulated to look strong, which is why NSR is practically worthless today.
EDIT: After reading through this again, it may sound like a joke. So I challenge anyone to clear up any misunderstandings you think I may have made. I am serious, it is this ridiculous.
