I have found a site now, and they list ways to earn money. Some are a bit risky and some you have to invest time and money to get a good return, but some are entirely risk-free and don't cost anything. If you want, I'll give you the site, to sign up and have a look. Obviously, you don't have to do anything, if you think it looks a bit too risky.
Why don't you just go out and get a job in real life instead of trying to earn money online. 90% of those offers are scams, or you have to go through so many advertisements, and installing spyware onto your computer, that it is not worth it whatsoever. Of course some of them are real, but all of them are sketchy. They make you jump through so many hoops just to be eligible for the money, then delay as much as possible in hopes you will forget about it, or do something that would make you ineligible. If they want you to invest money in it, I can guarantee it's a scam.
These ways aren't a substitute for an actual job. It helps me being a full-time student. It helps me earn a little on the side.
