* 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}

"someone spent a lot of computational power and time to bruteforce that contract address
so basically to have that many leading zeros
you can't just create a contract and get that, the odds are 1 in trillions to get something like that
there's a way to guess which contract address you will get, using a script.. and you have to bruteforce for a very long time to get that many leading 0's
fun fact, the more leading 0's a contract has, the cheaper gas will be for users to interact with the contract"

Levi Ninja is a key character of Attack On Titan. We added the Ninja element into Levi for creating a new meme token.
“I want to put an end to that recurring nightmare, right now.”
“There are those who would get in my way. But I'm fine playing the role of the lunatic who kills people like that. I have to be ready to rearrange some faces. Because I choose the hell of humans killing each other over the hell of being eaten.”

*
* 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}.

Alpha Coin
Perfected Tokenomics
Welcome to Alpha Coin, a decentralized platform consisting of the latest in Financial tools designed by some of the leading developers in the world and fueled by Alpha Coin, the first & native cryptocurrency of the Alpha ecosystem. Alpha is already developing a city within the Metaverse where multiple streams of income will be injected back into Alpha Coin via buybacks & marketing. The builders have been hired, the designs are ongoing and Alpha Coin is putting the world on notice.
Fixed supply:
10,000,000,000 Tokens Minted
Tokens Burned:
50% Burned at launch
Formula:
6% Marketing, 3% Liquidity, and 2% Reflections.
No Presale:
A private sale was already held to raise initial liquidity of $25,000.
NFT's:
Our first collaborative NFT collection will be available to mint the same week of Alpha coin's launch. All profits from NFT sales will be used for buybacks, marketing & to pay our development team.

/**
* @dev Hook that is called before any transfer of tokens. This includes
* minting and burning.
*
* Calling conditions:
*
* - when `from` and `to` are both non-zero, `amount` of ``from``'s tokens
* will be to transferred to `to`.
* - when `from` is zero, `amount` tokens will be minted for `to`.
* - when `to` is zero, `amount` of ``from``'s tokens will be burned.
* - `from` and `to` are never both zero.
*
* To learn more about hooks, head to xref:ROOT:extending-contracts.adoc#using-hooks[Using Hooks].

The APE’s Dream is an otherworldly replica of the original Caesar's Workshop, now called the Abandoned Caesar Workshop under the Caesar's Ape Colony.
Created by Caesar and Malcolm, the Caesar's Dream was originally intended as a way to ensure there were always hunters to fight humans.
Caesar eventually realized that the Dream was bound to his consciousness, with each requiring the existence of the other,
and nearly went mad from the revelation of never dying yet serving an eternal cause.
The APE's Dream acts as a central hub and sanctuary for Ape warriors, where resources can be exchanged and weapons can be fortified here,
as well as a connection to every other location in Caesar's kingdom.
Gibber is now trapped inside the APE’s Dream and he decided to turn this endless loop of dream into a endless profit generating machine by establishing a treasury fund.
A REWARDING mechanism can be easily achieved due to our unique treasury fund. 11% tax will be charged in each transaction and automatically added into the treasury fund.
This treasury fund will be used to reward token holders each month and the rewarding method will be decided by our DREAM DAO.

/**
* @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
* behind a proxy. Since a proxied contract can't have a constructor, it's common to move constructor logic to an
* external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
* function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
*
* TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
* possible by providing the encoded function call as the `_data` argument to {UpgradeableProxy-constructor}.
*
* CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
* that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.

Spades Token aims to create an ecosystem that solves and simplifies some important problems in supply chain management
including a gambling system for all holders to bet against eachother in various casino-based games.
❓ What's the difference?
* Community Governance - Spades Token holders have the right to cast vote/give opinion on almost every issue.
* Fair Distribution - The first distribution of Spades Coin will be sold via a silent and fair launch.
Matters related to token burning will be evaluated by community vote.
* Inflation Protection - The fixed staking program allows Spades Token holders to earn passive income.
* Gambling - There will be multiple casino-based games including a sports betting system which will require SPADES token.

* We have followed general OpenZeppelin Contracts guidelines: functions revert
* instead 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}
