Tell me please, I kept the NXT coins on my wallet to get the Ignis, I still need to keep them or can already be taken out? Only to be guaranteed to get the Ignis
As you as you keep Nxt in you wallet while snapshot took place, you will get Ignis.
when ignis tradable on bittrex
Ignis (IGNIS) is the first child chain of the new Ardor blockchain platform which will become operational at 12:00 AM UTC, on 1/1/2018.
So It won't be tradable before that time.
I bought nxt on 12/29/2017 can I get an ignis at 1.1.2018?
