I do withrawal my coss tokens yesterday and still not have it on my eth wallet.
I had 2 times email to confirm withrawal once yesterday second times today few hours before but even after confirm I no have my coins in wallet.
And this exchange is very slow its looks like giant lags but only very few people trade so I no have idea what happen when come more people it looks like always long loading every page on platform and exchange. Its need rebuild from beginning.
Its slow and buggy exchange nobody want trade there.
Fortunatelly I have from ICO time small number tokens and send them to this exchange only for test not large numbers so I can sell it if not come to my wallet or accept if they lost

Another weak Ico. Its happens.
Why are you writing all this here? Go and study first all about the sharing! Every day the same! After 2 days the new UI, after 2 weeks the new engine and API! Go to another exchange!
