I do not think demo account are purposely made easy. They give the same quotes as real accounts do. At least with the demo accounts I ever had they did. The difference is the demo is loaded with fake money as if it were real. They allow a trader to learn Forex and become experienced and also they are great for testing trading methods or expert advisors. The only other thing that may be different between the two accounts are the quality of order executions.
Jesus Christ is the only answer!
