PTC stands for paid to click. You basically get paid money to click on ads. It doesn't require any investment and it is a very simple concept. View advertisements for a specified period of time and get paid. o1 or.02 cents for doing so.
I actually tried this out but I didn't really like the low income potential when going the free route. The free route just means you click on advertisements, view them, and try to get referrals the free way to increase your earnings.
There are certain ptc sites where you can purchase referrals and earn more money but we are talking about how to earn money online without investment so that wouldn't be relevant in this case.
I would only recommend this method for those wanting to make a small amount of money for free.
