770 million dollars collected by Addsbook.com from 400,000 investors.
The site launched the end of the past year 2016 and the activity of this site is to pay money with bitcoin for its members and in return they click on the advertisements of the site.
The site lured the members to invest their money to earn more, this Indian site used the superstar shah rukh khan in television advertisements and this gave more credibility for the site.
This case is under investigation of the Indian authorities.
I think the last option to invest your money, is to give it to other people rather than you.
