The question of whether to accept NBT or BTC is a question of whether we are going to support our currency now, or possibly using BTC to support it later (the funds could also be used for development that wouldn't support the currency in the direct, open market sense).
Where the organization has been quite guilty of not properly supporting our currency this last month, I think we should choose actions that directly support our currency now. Requiring payment in NBT tends to result in NSR buyers purchasing NBT on the open market, which when combined with the burning of those funds, lends considerable price support to NuBits. Let's support our currency by inducing NSR buyers to first purchase NBT. Then let's reduce the NBT supply by burning proceeds.
I can see why @mhps has suggested selling NSR for BTC. With NBT falling, contractors want payment in BTC. While we do have some BTC available for that purpose, we need to focus on making NBT stable enough that our contractors will accept it. If we can't get our own contractors to use NBT, then who will? Let's make NBT usable.
While I still support a peg and a buy wall being put up, requiring payment for NSR to be in NBT is a very important and effective way we can support our currency right now, even if we don't have a peg or buy wall.
NSR demand is low because we have failed to support our currency adequately. If we make supporting it our highest priority, I believe the market will reward us with some additional NuShare demand. This is about integrity and trust.
