How to Recognized an HYIP Scam

• The promise of high daily, weekly or monthly returns.
• An offer from the company to pay “referral fees” to investors for bringing in additional investors.
• The use of social media to spread the word and praise the program.
• The promoter provides very few details about who runs the company and how profits are generated.
• The promoter may require that the investor open an e-currency account to invest. E-currency accounts are not licensed as a money transmitter.
