Hi !

I asked Yobit support why deposit/withdrawals are frozen and here is the answer...

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.
If you have updated the source code of the coin, send us (https://yobit.net/en/maintenance_request/ Free)and we will promptly correct the problem on the coin.
Thank you for contacted the support
