Ok thank you for the help.
Ok, I have checked the blockchain state as promised above.
The blockchain is ok and is moving well, but the network is extremely weak. In fact my wallet has found only one up-to-date connection: 213.108.119.84:41414. Thats not much, but enough to synchronize with.
I also went ahead and made a small test withdrawal from Bluetrade to my local wallet. It went well, I got it in my wallet in less than a minute, and there are already several confirmations in less than 10 minutes.
So the problem is not the network, the problem is Yobit.
If you can make Yobit update connections on their wallet, your can have chance to get your funds. I doubt it is worth the effort, but you can try if you want
