hmm…way to put me on the spot 
My short term vision for NuBits is as a hedge against fluxuations in the value of other ( non-pegged ) crypto assets.
In the long term i can imagine limitless possibilites, but dont want to sound too optimistic; it can be used as a medium of exchange.
For NuShares: stake-based voting is a big leap forward, and i can imagine this technology ( or a tweaked version of it ) used for governance.
