I see Graviton has added it to dgex and I worry that this might all just be a ridiculous joke at this point.
DGEX is poised to become a multi-currency exchange. Adding NAS was probably more motivated by the vision of expanding DGEX than 1 million NAS. I expect we will see more currencies added to the exchange in the near future.
The above poster mentioned that it was 100 million Nas to be given away to Dgex. it is 1% of Nas. I am afraid people will call it bribery. It is very bad for Dgex to do so. Remember that btc-e never get recovered from Nova's bribery even btc-e claimed that they destroyed the Novacoins they received free.
