Nothing is safe. That is the reality, and we can't change that, no matter what we do. What we can do is prevention and use the exchange for trading purposes, not as a storage wallet. Because I know that this is a common practice of some traders, and they should realize the risk attached to this idea, because a sudden collapse can't be reduced. We'd rather be more cautious than be sorry.

Aside from that, use a reputable exchange as much as possible because they will inform us once there is something wrong with them. At least, we still have time to withdraw our funds.
