Thinking of buying refferrals(ptc sites)...which site is the best option??

The answer is simple. NeoBux. The only what I trust because they have instant payouts and more importantly they are here for more than 2 years now. The second would be OnBux, it were born this year earlier but they are runed by a registered company (like neobux). If you have luck you can buy bots but in this 2 sites you only rent them. You got them for thirty days for aroun 25 cents/ref. You have to do a lot of recycle to get really active refs but so far this two options are the most riskfree sites. Of course the main is that how much money you would like to invest. If you thinking on spending a few hundred dollars than go to neobux buy a gold upgrade. For detailed strategy: imfaceplate.com/cashgopher - and read article twenty dollars a day. Good Luck!
