Yes, there's no secret way on earning that amount weekly because the ways are exposed here in forum and with different blogs and threads. But if you are a trader earning this amount is more possible for you but you need to consider first on investing higher capital for you to generate good return.
Yes if you want to earn that amount regularly then you should also be ready with good capital to invest in trading as higher capital can only give you higher profits and if you invest low amount then even your profit margin will be low and it will take long time to earn that money with a small capital.
But that's where the problem is starting. Many of the people here specific with new comers, they want to earn higher but they are not willing to invest bigger amount or they don't have enough to invest. This amount is really good if you will have enough to invest or if not, you should learn a lot of skills to acquire this profit weekly.
