Bittrex just pissed me off. I wanted to purchase NXT through their platform. They wanted to go through enhanced verification process. However, rejected mine due to name mismatch. No reply for my mails. I think I wont be receiving these IGNIS.

Register on hitbtc exchange and buy NTX through their platform instead. There is no enhanced verification process on Hitbtc the way it's done on bittrex.
Hi
What time snap shot will be done and how long I need to wait before I can start trading NXT on bittrex? I'm newbie and I have a lot of NXT coins,little worried that there will be massive dump and I will loose a lot of $$.
And what with Ignis is that same dump straight after airdrop or is worth to keep for longer?
Thanks
No one knows the exact time but you can follow the NXT blockchain live link
hereto know when it will get to the exact block height for the snapshot.
There will definitely be a dump, infact current the price of NXT has taken a dip after the recent pump. But if you are more interested in IGNIS airdrop, hodl your NXT, get your IGNIS and wait for the next time NXT will rise in value before selling or set a timed stop loss order.
