So guys..
I have been into NXT for 2-3 years now, had some ARDR too and I really love them both, but.
Is ARDR going to replace NXT or just run on their network?
Was ARDR also heavily premined before it was released?
Where can I find more info about NXT/ARDR?
The very first post in this thread provides enough information to answer your questions.
Nxt doesn't go away when Ardor is released, both will run in parallel. What the market prefers to use more is an interesting question, only time can tell. Price volatility is to be expected when Ardor is launched.
