Sites that involve high risks are introduced here.
Please invest with caution as these kind of sites may scam you one day. If you are decisive on investing these ponzi/hyip sites, try to invest early when the site has just launched and try to cashout all your investments as soon as possible.
If it has been a long time the site has been opened, you should be more careful. It is too risky to make money online in these sites, do not invest more than you can afford to lose
