I'd like to quote 2 types of the frauds,
High yield Investment Programs and it's sibling
Ponzi Scheme :
High Yield Investment Programs
The Internet is awash in so-called “high-yield investment programs” or “HYIPs.” These are unregistered investments typically run by unlicensed individuals – and they are often frauds. The hallmark of an HYIP scam is the promise of incredible returns at little or no risk to the investor. A HYIP website might promise annual (or even monthly, weekly, or daily!) returns of 30 or 40 percent – or more. Some of these scams may use the term “prime bank” program. If you are approached online to invest in one of these, you should exercise extreme caution - it is likely a fraud.
Ponzi Scheme
A Ponzi scheme is an investment fraud that pays existing investors with funds collected from new investors. Ponzi scheme organizers often promise to invest your money and generate high returns with little or no risk. But in many Ponzi schemes, the fraudsters do not invest the money. Instead, they use it to pay those who invested earlier and may keep some for themselves.
With little or no legitimate earnings, Ponzi schemes require a constant flow of new money to survive. When it becomes hard to recruit new investors, or when large numbers of existing investors cash out, these schemes tend to collapse.
Ponzi schemes are named after Charles Ponzi, who duped investors in the 1920s with a postage stamp speculation scheme.
Ponzi scheme “red flags”
Many Ponzi schemes share common characteristics. Look for these warning signs:
* High returns with little or no risk. Every investment carries some degree of risk, and investments yielding higher returns typically involve more risk. Be highly suspicious of any “guaranteed” investment opportunity.
* Overly consistent returns. Investments tend to go up and down over time. Be skeptical about an investment that regularly generates positive returns regardless of overall market conditions.
* Unregistered investments. Ponzi schemes typically involve investments that are not registered with the SEC or with state regulators. Registration is important because it provides investors with access to information about the company’s management, products, services, and finances.
* Unlicensed sellers. Federal and state securities laws require investment professionals and firms to be licensed or registered. Most Ponzi schemes involve unlicensed individuals or unregistered firms.
* Secretive, complex strategies. Avoid investments if you don’t understand them or can’t get complete information about them.
* Issues with paperwork. Account statement errors may be a sign that funds are not being invested as promised.
* Difficulty receiving payments. Be suspicious if you don’t receive a payment or have difficulty cashing out. Ponzi scheme promoters sometimes try to prevent participants from cashing out by offering even higher returns for staying put.
