Moments ago I found and joined very professionally looking program – Bhvfund
Bhvfund seems to use custom programed script.

Best way to explain concept would be to quote it from Bhvfund web site:
Earn up to 3% fixed daily return for 80 calendar days 7 days a week
Each transaction is handled separately and has its own active period
Every deposit payment could be cancelled and withdrawn anytime you want
Principal payment ins't included in daily payments and will be returned after 80 days
Our affiliates could get up to 0.7% daily from deposits made by their referrals
All transactions between your BHV account and e-currency account are fully automated and instant!
