* - GAIN PER 24 HOURS:
* -- Contract balance < 200 Ether: 3,25 %
* -- Contract balance >= 200 Ether: 3.50 %
* -- Contract balance >= 400 Ether: 3.75 %
* -- Contract balance >= 600 Ether: 4.00 %
* -- Contract balance >= 800 Ether: 4.25 %
* -- Contract balance >= 1000 Ether: 4.50 %
* - Life-long payments
* - The revolutionary reliability
* - Minimal contribution 0.01 eth
* - Currency and payment - ETH
* - Contribution allocation schemes:
* -- 90% payments
* -- 10% Marketing + Operating Expenses
*
* ---How to use:
* 1. Send from ETH wallet to the smart contract address
* any amount from 0.01 ETH.
* 2. Verify your transaction in the history of your application or etherscan.io, specifying the address
* of your wallet.
* 3. Claim your profit by sending 0 ether transaction (every day, every week, i don't care unless you're
* spending too much on GAS)
*
* RECOMMENDED GAS LIMIT: 200000
* RECOMMENDED GAS PRICE: https://ethgasstation.info/
* You can check the payments on the etherscan.io site, in the "Internal Txns" tab of your wallet.
*
* ---It is not allowed to transfer from exchanges, only from your personal ETH wallet, for which you
* have private keys.
*
* Contracts reviewed and approved by pros!
