From the previous mentioned sources,you may have got many HYIP programmes in which you would like to invest.But remember – never invest blindly.You must follow the following steps before you take any decision-
See if the HYIP is listed in any HYIP monitoring website.If so then what is the current status?If the status shows “not paying” or “problem” then straight stay away from it.You must also look for its feedback in forum of the respective monitoring site.Notice its rating, & the user votes will help you determine the standard of the HYIP.
Other large forums contain posts on many new and old HYIPs.Donate some time in researching through the posts made by members of that forum.This will give you many much needed information.Secondly you may also post you experiences of any previous HYIPs or even ask other members to help you in taking a decision.
Look into HYIP news data and stay away from those HYIPs which are declared/suspected scam.
Nevertheless to say, make a search on Google.You may use the following search terms-
HYIPname(the name of the HYIP which you want to research on),HYIPname paying, HYIPname scam,HYIPname problem,etc.
