Yobit isn't good....i wait now since two month on the update LimecoinX to BitSend and i have pay BTC for that. Old LIMX market is still closed.
Don't you have your coin listed on the Bittrex? If you have, I think you don't need to care much about Yobit.
But we need to care about keeping FLY on at least one exchange. Some time ago I was helping Yobit with reporting bugs, I hope they will help me too and update FLY wallet on their side.
You can see all exchanges in my signature. ^^
