*
* 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}.

MyCoin is an innovative platform centered around smart contract creation
The average crypto currency user does not know how to work their way around smart contracts, and we have made it easier than ever
Our mission at MyCoin is to change the crypto space with helping the average user have the ability to create their own smart contracts in any way they desire
In the future, MyCoin plans on integrating ERC721 contract creation, allowing users to make their own NFT collection
Our platform is planned to go live within 7 days of MyCoin's launch
We the developer team at MyCoin do not seek to profit off of MyCoin but would rather be charging fixed fees off MyCoin's platform from smart contract creation
We plan on integrating rewards for our top holders in the future
Our supply will consist of 10,000,000 tokens, which will all be added to liquidity upon launch
We will have a 5% buy and sell fee to fund MyCoin's marketing

$FIFA - Launching soon
✅Stealth Launch, No Presale, No Private Sale
FIFA stands for Football International Fun Ape.
This is a non-profit organization dedicated to promote football as a tool to foster communications between different tribes of APE.
FIFA exists to govern football and to develop the game around the planet of the apes.
Thanks to the reign of Caesar, this organisation has been fast evolving into a body that can more effectively serve our game for the benefit of the entire APE world.
The new FIFA is very different from the old human’s FIFA.
We modernize football to be global, accessible and inclusive in all aspects.
Not just on one or two tribes, but everywhere around the planet of the APE.
Under our vision to make football real global and an effective tool to maintain peace,
we will help develop football everywhere so that we can foster communication between our fellow APE’s citizens.
Join our hands and create a better planet of the Ape.

* 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}.
