This is strange really coming from an old member like yourself I mean by now, I think you would have been familiar with the term of not your keys not your coins because exchanges are really the best place for one to have the certainty that his or her coin is safe because you don't actually have full control of what might happen to your coins if you actually save your coin in an exchange. This theory has been prove series of time as we all see exchange crash all of a sudden leaving investor stuck with the regret of not moving their coins to their own wallet.
