@masterOfDisaster Well it is a geopolitical fact that USD is losing its status as the world reserve currency.
The BRICSā agreement to create a BRICS bank back in July 2014 is one important indicator.
Basically the Bretton Woods agreement is being dissolved.
We are now converging to a basket of currencies instead of a single US dollar, in which the YUAN would be the currency with the highest weight I believe.
Even against bitcoin, it seems that the Yuan has the highest volume.

So yes the USD is maybe the most referred currency or the most quoted currency but certainly not necessarily the most important one in terms of liquidity or trade volume, imho
That should be taken into account when we need to consider other currencies to peg to.
@JordanLee alluded to the fact that developing Nuās community in China matters.
I think that developing Nu in Japan does too. Pegging a version of NuBit to JPY will be a natural step.
But in terms of marketing, pegging to USD makes sense.
There is also a cultural dimension to it. JL is probably based out of the US. Some important elements of NUās community are based out of the US, obviously.
A simple google search gives you the answer.
Nothing wrong with it of course.
