My preference would be to offer two “series” of digital currency products: Stable-Supply (SS Series) and Stable-Value (SV Series). You’re correct that it works perfectly with our “The World’s Best Stable Digital Currencies” tagline that has been the backbone of our branding since release in one form or another.
A NuBit is one stable-value unit of a digital currency, so it seems that a SS series of digital currencies should have a different naming convention. Options could include NuBTC or NuBitcoin to capture broader interest, or an entirely separate term altogether like a NuAsset or NuReserve. I believe @Nagalim is correct that we should consider the marketing appeal of it, but I am not in favor of using the term “NuBits” for a non-SV series of products.
Edit: Adding a SS Series of products might necessitate a brand focus adjustment from “NuBits” to simply “Nu”.
Sample description: Nu is a blockchain network that allows dynamic management of digital currency products using decentralized governance. It offers an SS Series of products for hardcore Bitcoin users, gold enthusiasts, and Austrian economists, and an SV Series of products for users who prefer to have their digital assets retain a constant fiat value. Nu offers experimental digital currency products that satisfy all different economic and practical uses.
This high-level branding approach was discussed before our September 2014 release, but we decided on a singular-product (NuBits) focus to quickly build brand awareness of our product. If the real issue facing blockchains now is governance (@CoinGame), it would make sense to refocus our primary brand on Nu (with an enterprise-level website like a NAME.nu extension) and then have separate sub-level websites for SV Series (NuBits) and SS Series (Name TBD).
The simple and fair solution would be to distribute ~15 million coins to their existing Bitcoin holders. B&C Exchange has plans to distribute a limited number of BKS to Bitcoin holders, so the mechanism exists (or will exist). Then, sell the remaining 6 million NuBitcoin over time. We would have a large, distributed base from the beginning, and future profit potential from the 6 million NuBTC.
