Yes I have lost money in ponzi scheme. I really regret investing money in high yielding investment program. At first the website that I joined is not a ponzi scheme, it's like a faucet site. But when they add the high yielding program investment it becomes a scam.Ponzi scheme are investment platforms that promise a 50% or more profit on any investment you set up with the scheme.
Some ponzi shut down and disappear with people's money after a few months and I see them as risky money doubling schemes.
Have you ever lost money to a ponzi scheme and how much did you loose?
