How about SQ Series (Stable-Quantity)? I like the idea of having a Q anyways, it’s memorable. So, SQ Series for fixed-supply NuCoin products, and SV series for our NuBit products.
Interestingly, nucoin.com redirects to Kraken’s exchange. I wonder if they would sell us that domain name.
NuCoin sounds great and it matches the existing naming structure for major cryptocurrencies. I like it.
Edit: Bitcoin-NuCoin is a bit awkward due to the double “coin” and varied capitalizations. What about B-NuCoin (B-NCN) for the Bitcoin-inspired product? That matches the naming convention for NBT products, such as US-NBT and CN-NBT.
