Due to the wide usage of the official Nxt light client feature (https://nxtplatform.org/download) and the Jelurida public node (https://nxt.jelurida.com), the lack of manpower for development and support, and no clear path to profitability, myNXT has closed new user registrations and will phase out the MyNxt web wallet feature by the end of 2017.
You can confirm this announcement in the login page of the myNXT web wallet, at https://wallet.mynxt.info.
You will be able to operate the myNXT wallet normally until November 30, 2017, and will be able to export the Nxt accounts in your web wallet until December 31, 2017.
For instructions about how to continue using your Nxt accounts outside of the MyNxt wallet, see https://wallet.mynxt.info/faq.php. If after reading you still have any doubts, ask in our NxtForum board, https://nxtforum.org/mynxt-info.
REMEMBER THAT MYNXT WILL NEVER ASK YOU FOR YOUR LOGIN PASSWORD OR YOUR MASTER PASSWORD. DO NOT SHARE THEM WITH ANYONE!
So it is VERY IMPORTANT that, if you still have NXT, assets or currencies in your myNXT wallet accounts, you take action before December 31. myNXT cannot access the contents of user accounts, so any contents in accounts that have not been exported by the end of the year will be lost.
We want to give a big thank you for your support, and we hope to continue to see you as both Nxt and ARDOR move forward!
