So glad to see Bittrex supporting these projects... Be attentive on the 28th!!! :)
"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.
500 Million IGNIS tokens will be distributed as an airdrop to Nxt (NXT) holders based on a snapshot of the Nxt bockchain on December 28th 2017. The exact block height is set to be announced by Jelurida (www.jelurida.com) one week in advance.
If you have a Nxt (NXT) balance on Bittrex during the December 28, 2017 snapshot, you will be additionally credited the equivalent amount of Ignis airdrop tokens on a 1:0.5 basis. i.e. 1 NXT on Bittrex held during the on-exchange snapshot will get you 0.5 IGNIS airdrop tokens. NXT held on orders will also be credited. Only the NXT held on your account is eligible for IGNIS airdrop tokens.
Bittrex will make all reasonable attempts to credit our users IGNIS but until we have a fully supported wallet, we can neither guarantee tokens or consider creating a market. We will continue to monitor the state of the codebase and network.
Note: Bittrex will be closing our NXT wallet and stop trading the token to take accurate snapshots of balances. If any NXT deposits you had sent to Bittrex are not settled (i.e. marked as pending) by 6:00 PM PT, on 12/27/2017 (1:00 AM on 12/28/2017 UTC), you may not be credited with IGNIS.
We would like to thank the Ignis team for working closely with us"
