The upcoming airdrop for the IGNIS coins already made NXT rise steadily over the last couple of weeks. Now also Bittrex, one of the biggest altcoin exchanges, confirmed the participation in the airdrop.

On 28.12.2017 there will be a snapshot of all NXT holdings. For every 2 NXT you own, you will receive 1 IGNIS coin on the upcoming ARDOR platform. Free money, basically.
If you want to participate in the airdrop, I would not wait any longer. I expect the price to keep rising till the snapshot date.
