COSS/BTC still not working. I noticed they removed deposits of BTC for new acc (a friend created one and could not find BTC for deposit), so they must be aware of the problem. I also sent an email to the support reporting the problem but got no response 
They would wanna address this because I created a new account and deposited BTCBTCBTC too, more than 30 confirms already and the money is nowhere to be found.
absolutely do not worry! I waited 5 days! this is a bitcoin problem, not a stock exchange.
