I need to earn extra money online,but how?

Tweet

I'm from Malaysia(Asia).I really need to make money online because i have to use it next year for my final degree project. I had try for treasuretrooper.com,inboxdollars.com, cashcrate.com and other paid survey sites.None of them work for my country because most of the offer are valid for US citizen only. And I had also try for google adsense but I don't earn so much. My dear friends,please tell me what is the best and legal way to earn extra money online for international people like me.
