Wallet is on maintenance.
The solution to this cryptocurrency will take some time, need to update the wallet.
We apologize for any inconvenience
Apparently, they've done this for a few coins. Wallet goes into maintenance for whatever reason. Trading is allowed to continue. Wallet never leaves maintenance.
Additional Notes: Since they don't let you know when a wallet is under maintenance, you get a nice surprise when you go to withdraw.
Over a month ago, BTD went into maintenance on Yobi, trading was allowed to continue. The coin has since switched to BTDX, but all they needed to do was update the client/daemon.
There's a ton of other coins this is happening to. You won't know unless you try to generate an address/attempt to withdraw, then surprise! Have to sell them back at a loss.
