/**
* It is "Smart Contract Bank" smart-contract.
* - You can take profit 4% per day.
* - You can buy insurance and receive part of insurance fund when balance will be lesser then 0.01 ETH.
* - You can increase your percent on 0.5% if you have 10 CBC Token (0x790bFaCaE71576107C068f494c8A6302aea640cb ico.cryptoboss.me)
*    1. To buy CBC Tokens send 0.01 ETH on Sale Token Address 0x369fc7de8aee87a167244eb10b87eb3005780872
*    2. To increase your profit percent if you already have tokens, you should send to SmartContractBank address 0.0001 ETH
* - If your percent balance will be beyond of 200% you will able to take your profit only once time.
* HODL your profit and take more then 200% percents.
* - If balance of contract will be lesser then 0.1 ETH every user able stop contract and start insurance payments.
*
* - Percent of profit depends on balance of contract. Percent chart below:
* - If balance < 100 ETH - 4% per day
* - If balance >= 100 ETH and < 600 - 2% per day
* - If balance >= 600 ETH and < 1000 - 1% per day
* - If balance >= 1000 ETH and < 3000 - 0.9% per day
* - If balance >= 3000 ETH and < 5000 - 0.8% per day
* - If balance >= 5000  - 0.7% per day
* - If balance of contract will be beyond threshold, your payout will be reevaluate depends on currently balance of contract
* -
* - You can calm your profit every 5 minutes
*
* To invest:
* - Send minimum 0.01 ETH to contract address
*
* To calm profit:
* - Send 0 ETH to contract address
