Have you seen the doubler site that is not scam. It is obvious that they all work according to the Ponzi scheme. There is no point in listing such pages, because thousands of new ones are created every day.
I beg to disagree.
There are lots of people, who are not members of the forum, that browse daily on the forum. Some of these people are newbies who have little knowledge about bitcoin or investing in general and they are interested in knowing such. If they visit a website which offers high daily returns, they may be tempted to deposit their resources on that project. I hope you give weight to my opinion and trust me as I am speaking by experience!
By creating threads such as these despite that they are not listed on the forum, it provides an extra layer of safety to newbies in the forum or to anyone who visits this website if they happen to check this board.
