What's the lack? Hackers are getting money in every few days from exchanges, this is shameful to exchanges developers. I wonder how those exchanges are running with huge trade volume that can't take users responsibility and can't assure the security. I'm feeling sorry for them who loses their money in this criminal activities.
I've read that coinrail will stores their assets in a cold storage after the hacking occured. I mean, what they are doing with their security before they got hacked? they just wanted to fix something that's not right only when it becomes a disastrous problem and people are losing money. This kind of exchange is what grind my gears the most, they just can't get thing right until something really bad happened, really hope that they learn from it so that they will improve their security everytime because no system is safe.
