Volume on Yobit dying? Publicity is publicity although they may just be coming to their senses.
Yobit does big harm to price discovery for any IOU's they trade .Would like to see coinmarketcap.com stop listing so called Pre Launch exchanges and their market charts.
If you want to trade your future liabilities you must provide a buyer with some kind of agreement and guarantee ideally covered by assets you hold. Otherwise you can just walk away without any consequences.
Hope publicity, as you say, will take care of it in a long run.
