Hello,
Exchange
https://yobit.net/en/trade/MXT/BTC is in Maintenace.
I opened a ticket and received a reply:
Support answer:
Good day.
Deposit\\Withdrawal coin will be available after you upgrade the source code of the wallet.
Unfortunately the developers are in no hurry to send you updates - therefore,
in order to avoid the loss of users, the network is not available.
When can I take off again from Yobit,
are they doing the update?
