 *                                     * WALLIE - distribution contract *
 * 
 *  - Growth of 1.44% in 24 hours (every 5900 blocks)
 * 
 * Distribution: *
 * - 10% Advertising, promotion
 * - 10% Referral program
 * - 3% Cashback
 * - 5% for developers and technical support
 *
 * Usage rules *
 *  Holding:
 *   1. Send any amount of ether but not less than 0.01 THD to make a contribution.
 *   2. Send 0 ETH at any time to get profit from the Deposit.
 *  
 *  - You can make a profit at any time. Consider your transaction costs (GAS).
 *  
 * Affiliate program *
 * - You have access to a single-level referral system for additional profit (10% of the referral's contribution).
 * - * - Affiliate fees will come from each referral's Deposit as long as it doesn't change your wallet address Ethereum on the other.
 * 1. The depositor in the transfer of funds indicates the DATA in your e-wallet Ethereum.
 * 2. After successful transfer you will be charged 10% of the amount of his Deposit.
 * * 3. Your partner receives a "Refback bonus" in the amount of 3% of his contribution.
