There are many ways to make money online. But first, they must have some online wallet, like Paypal or Alertpay, as their payment processor.
If you want to get money online, be sure to join some forum which involved in money making, url://earnmoneyspace.com, can be very useful. Remember here, making money business always involved with community.
Next is, obviously, looking for the legal site which you can trust to work and invest. A big and trusted site can be easily found, like Neobux or Palmbux, the other is, you can ask your friends in a forum. They can always provide some useful information.
The other one is HYIP, High Yield Interest Provide, which like an investment program where you can invest your money there and after a week or a month you can get the interest and your principal money.
Sounds good, but you have to be careful since (remember this) all HYIP is a scam. You can only get some huge stash of money if you know where is the site which going to be a long term scam that still pays its investor for a long time.
As I said before, information is very important. Happy earning!
