Again we saw an exchange got hacked. There would be nothing to hack there if people didn't keep their coins on exchanges! For the love of Dog (lol), don't keep your coins on exchanges, start practicing safety, this is your investment we are talking about!
Very amazing advice you have here, keeping your coins in an exchange is not very safe practise because many exchanges are potential targets of hackers. I think it's very necessary to keep your coins in a private and well protected wallets.
