CNO is de-listed by SwissCEX (as usual; without any warning,unlike what Bittrex does.)
Yeah, they don't seem to have that right just yet.
One coin they delisted, they disabled the market, but not the orders (so you had to manually cancel them to recover your balance)
Another coin they delisted, only deposits and withdraws were disabled, but if you had a balance you could still buy and sell.
This sort of thing is a bit amateurish.
