Mutual Uniting System

/* MUSystem is a global Savings system 
based of the mathematical algorithm created 
by the Mavrodi brothers - Sergey and Vyacheslav. 
The solidity code was written by the enthusiast and devoted MMM participant.
According to these rules MMM worked in Russia in the nineties.

"MMM IS A FINANCIAL NUCLEAR WEAPON.
They say Baba Vanga predicted, “Pyramid from Russia will travel the world.”
When Sergey Mavrodi passed away, many people thought this prediction 
wasn't going to come true. What if it's just started to materialize?"

Financial apocalypse is inevitable! Together we can do a lot!
Thank you Sergey Mavrodi. You've opened my eyes. 333555*/
