Sorry to say this, friend, but there ain't any shortcut to earn money, especially when you don't have much money to invest.
Needs a lot of luck, hard work, and consistency.
Some ways you can make $20/day are
- learn some skill and sell it(you gotta figure out how to sell)
- Adult CPA or something like e-whoring(takes a lot of patience)
- VA jobs( again if you have some skill, find someone who can provide you a job (often you need to wok for cheap and not worth if you are from developed countries)
- Get a job( work on mc Donald, burger king, or any place for salary- Invest the money in things that could give you a good return)
Basically, try and test things, don't lose hope, browse the forums and test the methods. Work fucking hard and smart, and one day you will find something that will make you more than $20/month. But brother, no one gonna help you to earn money; you gotta figure it out by yourself.
