you gotta see hyip as investing...
just like when trying to pick which company to invest with, you have to investigate and research the hyip.
Though hyips may result in higher returns, the sacrifice is security... While companies can't disappear in 1 hour (assuming you know the company you invest in has a physical location), a hyip admin can simply walk away with the $ without a trace
If you really want to go with a HYIP i would go with 12dailypro but I would prefer something thats been out for over 2 years since they have proven stability. So in my opinion i would recommend you to join studiotraffic. I have been with them for a long time and they do payout each and every month. Cant go wrong with that!
For the most part, you'll find a lot of negative predictions and bad talk about 12DP on these forums, but I've found them to be a great company and I don't believe they are going anywhere.
