The front page of www.nubits.com has six different large functional areas that we consider core benefits of using NuBits. From an exchange’s perspective, the main one is “Trading”:
If traders on these exchanges believe the value of their holdings will go down, they will sell their digital currencies for fiat money such as US dollars. The traders then need to either hold the fiat money on an exchange (which can be a target for theft) or withdraw the funds (which can be slow and inconvenient).
NuBits eliminates this frustration. Traders can purchase NuBits as a stable hedge rather than liquidating their holdings to fiat money. These NuBits can then quickly and easily be transferred off exchanges into private wallets. NuBits makes trading digital currencies easier.
What this means is that your users can rely less on USD, and instead hold NBT as a tool for maintaining the USD value of their portfolios. I would imagine that your primary concern is trading volume (for the fees), and that holding additional USD on your exchange only introduces more regulatory/compliance risk.
Of course, in the long term the main benefit of offering NuBits trading is that the market will be demanding it. 2015 will be the year that stable-value digital currency projects become the norm. Of all the projects that currently exist (BitReserve, LOCKS, CoinUSD, BitUSD, Tether, etc.), NuBits has by far been the superior competitor regardless of what metric you use to evaluate success: price stability, liquidity, decentralization, or user simplicity.
