Ojooo is a good site for online earning but the thing is its a ptc site and gives less money but if one has a good fan following and a good circle on youtube or any social media than he can earn atleast 1000$ a month by just refering and doing nothing.
I have used this site and without any referal in 1 hour I earned 0.020$ .
It is good for a person who can get a lot of referrals and without refearal one can earn adound 10$ a month just by watching ads and posts.
