Neobux.com is a PTC site and it is just a waste of time. For clicking one advertisement they give 0.01$ and the minimum payout amount is 2$.
But the real problem is you dont get too many advertisements to click. Everyday you get 5 or 8 and you only get 0.08$ a day. So you need to wait for months to get your 2$. There you can refer and earn more dollar but I dont think they will not pay much for it. It is totally a waste of time.
