I have two more questions.
1. In the noirds.com, there is a word "Doubles as both currency and equity for the NIG group."
   I don't clearly understand how it works. So the NRS supply doubled and my NRS in wallet also become doubled?
   And the measurement of currency and equity is done by algorithm or dev team?

2. To get the POS, does the wallet should always be opened? (i.e. always running on my PC?)

Thanks in advance.
