It is for their own security, if they don't want to disclose how much Bitcoin they are holding at then it is their choice and we cannot force them to tell it and they are not oblige to tell those information to us too, so I don't see anything wrong for that, whether they are lying or not, it doesn't matter at all, what we should matter is what we are holding on our own.
