Are you talking about Egold token? Which is this eGold Announcement?

It seems an abandoned project no update and someone telling that eGold is scam.

eGold is also listed on southxchange from here https://www.southxchange.com/Market/Book/EGOLD/BTC
It is just another option but I don't know if they are safe to trade but if the eGold is abandoned by their team there is a possibility that you can't exchange this token it might be a wallet issue so exchanges wallet also affected.

Why not, try to exchange a small amount in yobit first if it works then exchange the remaining amount but if not, better to hold that token and wait for new exchanges to sell it.
