HI, When is the official airdrop of Ignis for NXT Holders? So for now transfer all Ardor to NXT wallet. Then when Ardor launches we have to manually transfer them to the Ardor wallet? Is this correct? Thank you.
You do not have to manually transfer anything, as long as the Ardor are on the wallet they'll be used for the snapshot, and you'll get your final Ardor on launch.
