But it is highly shady practice to delist coin without clearly stating why... Actually it could be immediately considered as probable insider trading. While every move like this highly influences price, and if coin has no signs of problems before and was dilisted out ow nowhere.. really shady.

Even if coin breaks some of the rules it must be clearly stated to raise community awareness.

And when healthy coin looses 40% of the value just because someone had a bad day it is unacceptable.
