Here you just need to click ads everyday. You will get a little amount of money with that. But if you manage to make referrals, you are done. You can easily make a decent amount of money. And if you can't make referrals, then click ads everyday and rent some referrals for 1 month. This way, keep renting referrals and keep maintaining them. Then you will have easy money with no investment!
