Earning online is great opportunity for extra money. I work online for about 6 months, and you have many ways of earning from small jobs to serious one. For small jobs (micro jobs) you have great sites as Jobboy,Microworkers, MicroTasks and so on.PTC (Paid to click) are great sites, but you need to be careful because most of them are scam. On internet you can check them, I recommend you to join only to sites which pay, you can google them. You can earn from your blog or websites. With all these jobs you can earn up to 500$ a month. If you want to invest money you have few sites, like just been paid – you can triple your money in 75 days. Or on penny stock. Many ways are there, you just need to find yourself in one of them. Good luck everyone!
