there are many ways to earn much money per day and really $10 is nothing to be earned .
its just depend on your experience, you may trade in forex ( IF only you are an Expert and Good Analyst ) and thus you will be earning more than 10 x of what you wish .
or if you have some experience about SEO and google adsense then you can earn well through it .
there are many important fields where you can earn alot of money but you must have the experience as there is no place for newbies except dreaming at ptcs , pts ..etc .

Best of Luck,
