this doubler is only good for a week after they made profit, they will take the site down.
Site that OP posted is offline, what happens is the following:
In the past the Hyip/ponzi sites managed to survive for a few cycles, there were several hyip/ponzi sites that survived for 1 year, but gave returns of less than 1% per day or every 5 days and those people who like hyip sites would know who were the administrators of the best hyip sites and every time these administrators launched a new hyip site in the first days of the site’s life it managed to reach many investors or players, but over time (in the last 4 years) things have changed, the worst scammers began to flood with hyip sites that promise extremely high and illusory returns.
I am not defending the hyip sites of the past because they are still hyip/ponzi sites, I am just telling the story I saw because I read comments in a very popular Portuguese forum in the past, in times when PTC sites were also very popular
