I've been with Neobux for over a year now. I make about $3/day with Neobux.
You will only make a few pennies per day by clicking the ads. The only way to make money with Neobux is to get referrals. The more you get the more money you earn.
There are two types of referrals on this site: rented and direct. The real money is with the direct referrals. Many people spend money on the rented referrals and lose the money. That is why so many claim there is a Neobux scam.
Over the last year Neobux has added other methods to earn money so it's more than a PTC now. You can earn money from offers, completing task and watching videos. Again these are small money and truthfully I have not explored these options yet.
