I really do not know why newbies do not listen to our advice, one of the most common advices is that you should never store your coins in an exchange there are many things that can happen, the exchange may disappear, the exchange may get hacked, maybe a worker in the exchange steals the funds or a government may intervene and seize the exchange, I know it is a lot more convenient to keep your coins there but then people that do that should not cry about losing their coins, if they care so much about their coins they should have taken measures to protect them.
