LoL, there's actually someone on the CoinEx thread saying how people should have learned from the Gox collapse not to leave coins on CoinEx as he's now lost all his coins.

Well, DUH!!!

How many times do people have to lose their coins before learning that an exchange is NOT a secure wallet where you can get big rewards without high risk?!!?

PLEASE REMEMBER, Exchanges are big targets for hackers as they hold a large percentage of their coins in hot wallets unlike wallets where far more can be in cold storage.
Only leave on an exchange what you're looking to trade, withdraw and deposit for the big price fluctuations. Day trading won't make you super rich, it's not worth losing everything for!
