@PaulDMachado, If you were holding NXT on bittrex on Dec 28 at the time of the snapshot you should have gotten them already. If you dont have them, that probably means you werent holding NXT. Or they messed up, which i doubt. I got mine yesterday without a problem.
@PaulDMachado, If youre positive, and you got the proof, then they will credit you. They're a good exchange, they'll do the right thing. Most people are just impatient, stupid, and have no idea what they are doing. So they're clogging up the entire system, and its hard for the exchanges to keep up.
@PaulDMachado, I believe you sold too early. If I remember correctly, the snapshot was roughly 5a-6:30a CNT, which would put it at 6a-7:30a for you. People sold really early before NXT hit the proper block height of 1636363. A lot sold almost at midnight thinking that the snapshot was being done there, but they estimated that date because of the block height to be done at that specific day, not a known time. I can not find a site to verify the snapshot time but the following link was made the 28th of December and people thought that it had happened but it hadn't at that point. https://www.reddit.com/r/NXT/comments/7mjqi7/ignis_snap_shot_in_2_hours_and_43_mins_wth_is_nxt/
