No, there are no issues with the coin. That happens sometimes with exchanges, best thing to do is contact yobit support, be polite and patient.
Do you work for YoBit? Because, you're giving a definitive answer that they are not having an issue with the coin.
I'm telling you, from my experience on their platform, when withdraws are delayed an extreme amount of time, it's usually due to an issue between the exchange and the wallet.
While my BitcoinTalk profile may say "noob", this certainly isn't my first day. I have, actually, already contacted them without any response back. I don't need to be told to do so, nor be told to be "polite and patient".
