Do not believe the bonus offer from CashFlow Investment (cashflowinvest.org). The turnover requirement is designed so you can never withdraw. I learned the hard way. I deposited after my brother mentioned them and the bonus terms were buried in pages of small print. My fault for not reading but their design is predatory.
