No you should not.

With 400$ if you are genious who can make 100% profit you would get 400$; the chance is almost 0%.

Professional traders can make about 3 to 5% a month, why they can not make more? Because if they try to make more they will lose all.

If you are lack of capital, I suggest you try demo contest which is free to prove you can make 100% profit and get a prize.
