It is so very true about trusting the exchange, you just use them but you don't wholly use them. When you trade, deposit only the amount that you'll be using for trading, none other than that.
You can add to it that you don't have to be hyped with any popular person that gives his insights about the market. Like the typical thing when there's someone popular that gives advice about what he must do and the media hypes it. There were many people that have done the wrong thing of believing those.
