My understanding is that you'll get as many Ardor tokens as the average of your NXT balance during those three months. Ardor for the price of Nxt now, and I get to keep ½ of my original Nxt too! Correct me if Im wrong.
https://www.nxter.org/the-nxt-2-0-token-distribution/ Not sure though; when things look too good to be true, they probably are.
then let me save your investment!
there used to be a free distribution of ARDR for NXT holders, but it was last year
ARDR right now is a token (asset) on the NXT blockchain
Once Ardor goes live, ARDR tokens will become real ARDR on the Ardor blockchain at 1:1 rate
if you want ARDR, you have to hold the ARDR asset in your NXT wallet !
however your NXT will give you free IGNIS (ardor first child chain) at 1:0.5 rate
