Are devs in negotiations with Yobit about wallet update? My xby are in Yobit. I am afraid I am not the only one... Or we have to assume our funds lost due to Yobit lazyness, conscious or unconscious. No difference!
We have contacted YoBit numerous times. At some point, they may just take the wallet out of maintenance. Then you'd really have to jump and get your coins out of there quickly.
As for as updating the wallet to the current version? They are notoriously slow in doing so, if they decide to do it at all.
Most of us know the risks with Yobit, and still some choose to trade there. I do on rare occasions now . .
I hope you are able to move your coins off very soon.
