I just changed my payment settings to NXT coin and I got this information from Bittrex when I created my NXT wallet-adress:
I've got the messagecode from Bittrex, but when I added NXT coin to my payout adresses I couldn't find anywhere to include the message. Just the wallet adress as usual."When depositing, please send your message unencrypted. Please do not send multisig or phased transactions. They will not be credited.
If the message is not included in your transfer, we cannot credit your account. Please do not directly deposit from an exchange or pool unless they allow you to specify a message."
What am I missing? Thanks for your help!
