@Stompix, you know how people are, as soon as they see that transactions are made from some publicly known address on CEXs, most of them immediately think that the coins are for sale - although if you send to CEXs, then your intentions are quite clear, unless you are playing a dirty game and want to a way to cause panic and crash the price.
Also, many of us don't know the exact way things work in Germany, but if it's a crypto company with experience, then I guess they know what they're doing. I would still say that they messed up a bit, because they could have done it quickly and efficiently without affecting the price for days - sell everything in one day (if possible) and be done with it.
