In fact, I don't sympathize with people who are cheated. Pizza doesn't fall from the sky. Greedy people will eventually be killed by themselves. With such a high return, I believe no one will sue you for this opportunity. This is human nature.
Those who don't understand how the market works and how people get scammed will fall for high return schemes which are essentially scams or pump and dump. There are those who hunt for such projects and they might make money but in reality most of them are going to lose which includes the common folk at this forum.
The way to avoid this is not to get greedy, but keep patience to buy low and sell high.
