No it won't. All the coins that claim to be nation coins have failed big time till now.
According to your standard bitcoin was a failure as well in the day.
I think we need to look at this down the road...in a year or 2 and then decide.
Bitcoin never claimed and it wasn't intended for it to replace any national currency in the first place
This whole charade started by auroracoin will end up badly for people who put money into this
Guess you're one of the bagholders of these coins... do you have any aph?
I have no AUR or ISR but just a bit of some others ( very small amounts and not big hopes for them at the moment but can't hurt)
I have also some other alt's -small amounts of quite a few. Some will die and some might thrive. I have plenty of patience.
Maybe it will end up badly and maybe not, same was said for bitcoin ( and still is) by many people.
Some may be scams and some not. All I say is not to judge so early.
No "national coin" will replace the local currency as bitcoin won't. But to survive along side? maybe.
