I think users should not leave BTC at exchanges. In such cases, you will have control over both coins in case a hard fork occurs. You also minimize the risk of losing money if exchanges get hacked.
I would say the same when it comes to saving your coins in other exchanges but when it comes to coinsecure if Benson Samuel says so i trust him.

Will do a blog post or mailer over the next few days explaining our stance.
Good to hear from your buddy,hope to hear the official stance from coinsecure in the coming week. What is your general opinion regarding the scaling issues,what is your suggestion to overcome the network issues.
