The admin of a newly launched project FlexibleInvest (flexibleinvest.com) has informed about improvements in the project that should be expected in the nearest future. A PTP system (Pay To Promote) is promised to be launched in order to attract more potential customers and give everyone interested the opportunity to earn not only by investing money but also by promoting the project. It will be possible to earn even without making a deposit, and more details will be provided as soon as PTP system is ready.
Meanwhile, you have an opportunity to receive money prizes by referring new investors to FlexibleInvest and the first person who attracts 10 active referrals will receive $100 prize that can be withdrawn via any of the accepted e-currencies: LibertyReserve, PerfectMoney or AlertPay. Read more about a referral competition here (http://flexibleinvest.com/competition.php). The addition of a Proofs section is also announced in the latest update. You can visit it here (https://www.flexibleinvest.com/proofs.php). On that page you will see payment proofs with users' names and amounts paid out to one or the other payment processor.
I remind you that FlexibleInvest offers 1%-2.4% daily for 15-120 days. The minimum deposit amount is $5 and the maximum is limited to $25,000.
