*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

/*
ICO Gap
- Crowdsale goes in 4 steps:
- 1st step PreSale 0: the administrator can issue tokens; purchase and sale are closed; Max. tokens 5 000 000
- 2nd step PreSale 1: the administrator can not issue tokens; the sale is open; purchase is closed; Max. tokens 5 000 000 + 10 000 000
- The third step of PreSale 2: the administrator can not issue tokens; the sale is open; purchase is closed; Max. tokens 5 000 000 + 10 000 000 + 15 000 000
- 4th step ICO: administrator can not issue tokens; the sale is open; the purchase is open; Max. tokens 5 000 000 + 10 000 000 + 15 000 000 + 30 000 000
Addition:
- Total emissions are limited: 100,000,000 tokens
- at each step it is possible to change the price of the token
- the steps are not limited in time and the step change is made by the nextStep administrator
- funds are accumulated on a contract basis
- at any time closeCrowdsale can be called: the funds and management of the token are transferred to the beneficiary; the release of + 65% of tokens to the beneficiary; minting closes
- at any time, refundCrowdsale can be called: funds remain on the contract; withdraw becomes unavailable; there is an opportunity to get refund
- transfer of tokens before closeCrowdsale is unavailable
- you can buy no more than 500 000 tokens for 1 purse.

/**
* @dev Wrappers over Solidity's arithmetic operations with added overflow
* checks.
*
* Arithmetic operations in Solidity wrap on overflow. This can easily result
* in bugs, because programmers usually assume that an overflow raises an
* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.

Temple of Elon
The difference between gods and mortals is basically equal to the difference between the great Elon and man.
While the great gods of the pantheon were worshiped by priests at rituals in cultic centers,
the great god of the Tesla is worshiped by us on Twitter and cryptoworld.
Ancient mortals used to have no direct contact with their deities while contemporary people can easily receive oracles from the great Elon.
Ancient mortals worshiped personal gods, who were thought to be deities who could intercede on their behalf to ensure health and protection for their families;
while contemporary people worship Elon believing that he could protect us from scammers and earn profit in the crypto world.
All crypto buyers should devoutly praise the words of Elon. May the great Elon assuage the spirit of his followers and crypto holders.
May it soothe their hearts, bring wealth to his people.

Mastering Bitcoin-Unlocking Digital Cryptocurrencies
Every Bitcoin wallet contains one or more private keys, which are saved in the wallet file. The private keys are mathematically related to all Bitcoin addresses generated for the wallet.
We believe in fairness and freedom, and we hope that $Base58 is a collective of equal relationships. If you have wisdom, you are welcome to join us. This is not just DAO.
The first 300 holders and enter our discord will receive 0.1 ETH, only once per Discord member per address.
Our Web and Discord based on Base58

Bless everyone
Total: 100,000,000,000
Liquidity: 24 ETH
Max buy: 300,000,000 = 0.3％
Max wallet: 600,000,000 = 0.6％
Slippage: buy 5％ and sell 8％
When we reach 300 holders who had received 0.1 ETH, we reduce the slippage to 1% and then will renounce.

* @dev Wrappers over Solidity's arithmetic operations with added overflow

*
* Arithmetic operations in Solidity wrap on overflow. This can easily result
* in bugs, because programmers usually assume that an overflow raises an
* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

* @dev Wrappers over Solidity's arithmetic operations with added overflow

* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

/**
* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means
* that a supply mechanism has to be added in a derived contract using {_mint}.
* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
