* - Minimal contribution 0.01 eth
* 
* - Contribution allocation schemes:
*    -- 90-95% payments to depositors and partners 
*    -- 1-3% technical support team 
*    -- 3-7% promotion
*   depends on the contract balance. more on the website SmartMMM.com
*
* - How to use:
*  1. Send from your personal ETH wallet to the smart-contract address any amount more than or equal to 0.01 ETH
*  2. Add your refferer's wallet to a HEX data in your transaction to 
*      get a bonus amount back to your wallet 
*      if there is no referrer, you will not get any bonuses
*  3. Use etherscan.io to verify your transaction 
*  4. Claim your dividents by sending 0 ether transaction (available anytime)
*  5. You can reinvest anytime you want
*    
* Smart contract has a "soft restart" function, details on smartMMM.com
* 
* If you want to check your dividends, you can use etherscan.io site I / o by following the" internal Txns " tab of your wallet
* Attention: do not use wallets exchanges - you will lose your money. Use your personal wallet only for transactions
