I would start with trading because of the fact that its easy and also very profitable with such amounts.
Trading is an option its maybe risky but I can see that its profitable and also worth the risks due to that of course.
but to generate profits from trading it will not be easy. you need to be familiar with the atmosphere of the market. if you're not used to it, you're just going to make the money that you have diminished in vain. well, with earnings of $ 40, you can hold it, and maybe make something bigger.
