Elon musk presents you his latest creation - the magic MUSKROOM !
Elon Musk is creating this product to bring joy to the world. Earth is not only full of pollution but also filled with meaningless hatred. By consuming MUSKROOM, you can enter the fantasy world that Elon Musk creates, you can see what he sees, you can feel what he feels.
This magical product is designed to make you feel giggly, excited, energized and a bit overwhelmed. People who take larger doses of MUSKROOM can act unpredictably. You can laugh a lot, become fixated on certain things, be emotional or falsely consider yourself as Elon Musk.
This Muskroom is limited in supply. Seize the chance and join us in the Fantasy world.

*
* 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.

*
* Free britney is a meme token with a twist!
* Free britney has no sale limitations, which benefits whales and minnows alike, and an innovative dynamic reflection tax rate which increases proportionate to the size of the sell.
*
* TOKENOMICS:
* 1,000,000,000,000 token supply
* FIRST TWO MINUTES: 3,000,000,000 max buy / 45-second buy cooldown (these limitations are lifted automatically two minutes post-launch)
* 15-second cooldown to sell after a buy, in order to limit bot behavior. NO OTHER COOLDOWNS, NO COOLDOWNS BETWEEN SELLS
* No buy or sell token limits. Whales are welcome!
* 10% total tax on buy
* Fee on sells is dynamic, relative to price impact, minimum of 10% fee and maximum of 40% fee, with NO SELL LIMIT.
* No team tokens, no presale
* A unique approach to resolving the huge dumps after long pumps that have plagued every NotInu fork
*

/*
キングエンジン($SKING)
Be aware monsters and jeets! The King engine is now on and the Ultimate Hellfire Burst Wave Motion Cannon,
which is powerful enough to defeat Platinum sperm and Evil Natural Water in a split-second, is ready to launch.
Despite not being the highest-ranked hero of the Hero Association,
he is considered to be the most powerful man on Earth,
and it is due to this strength that he receives praise and respect from fellow heroes.
His strength is so feared that criminals and mysterious beings will often surrender before having to fight him.
Can you hear the sound of the King Engine approaching?
King is serious and ready for the battle.
Can you feel the formidable impact imposed by the sound?
Saita KING IS COMING FOR YOU !

// The list below in the array listTINAmotley is recited in the video
// "List, Glory" by Greg Smith. The elements of listTINAmotley can be
// claimed, transferred, bought, and sold. Users can also add to the
// original list.
// Code is based on CryptoPunks, by Larva Labs.
// List elements in listTINAmotley contain text snippets from
// Margaret Thatcher, Donna Haraway (A Cyborg Manfesto), Francois
// Rabelias (Gargantua and Pantagruel), Walt Whitman (Germs), and
// Miguel de Cervantes (Don Quixote).
// This is part of exhibitions at the John Michael Kohler Art Center in
// Sheboygan, WI, and at Susan Inglett Gallery in New York, NY.
// A list element associated with _index can be claimed if
// gift_CanBeClaimed(_index) returns true. For inquiries
// about receiving lines owned by info_ownerOfContract for free,
// email <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="afe3c6dcdbfbe6e1eec2c0dbc3cad6efc8c2cec6c381ccc0c281">[email protected]</a>
// In general, the functions that begin with "gift_" are used for
// claiming, transferring, and creating script lines without cost beyond
// the transaction fee. For example, to claim an available list element
// associated with _index, execute the gift_ClaimTINAmotleyLine(_index)
// function.
// The functions that begin with "info_" are used to obtain information
// about aspects of the program state, including the address that owns
// a list element, and the "for sale" or "bid" status of a list element.
// The functions that begin with "market_" are used for buying, selling, and
// placing bids on a list element. For example, to bid on the list element
// associated with _index, send the bid (in wei, not ether) along with
// the function execution of market_DeclareBid(_index).
// Note that if there's a transaction involving ether (successful sale,
// accepted bid, etc..), the ether (don't forget: in units of wei) is not
// automatically credited to an account; it has to be withdrawn by
// calling market_WithdrawWei().
// Source code and code used to test the contract are available at
// https://github.com/ListTINAmotley/_List_Glory_
// EVERYTHING IS IN UNITS OF WEI, NOT ETHER!

*
* 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}.

The lost son of the infamous Dogefather. Shiba Inu killed Ryu’s father to take over the infamous INU corporation. Ever since, Akita Ryu has been on a
path to terminate all inferior Shiba’s and retake the DOG TITLE legacy.
AkitaRyu token is a trusted advanced cryptocurrency created and developed by Summit BC development team.
It will be the native token on SummitSwap, a platform for everyone.

Daddy Token $DADDY
$DADDY was created by a team of fathers in the crypto space who’ve come together
to highlight the mental health issues fatherless victims deal with and to celebrate
the importance of fatherhood. It is a space for women in crypto to feel comfortable
to discuss mental health and feel welcomed without judgment.

* TIP: For a detailed writeup see our guide

*
* 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}.

STRENGTH.
POWER.
NO BULLSHIT.
JUST PUMP.
SLIPPAGE 16% - No bots on contract, you will not be front-run.
☑️ Stealth-launch, no presale
☑️ Renounced contract
☑️ No max buy/sells, except small cooldown in the beginning.
☑️ A ERC20 meme token without developer & marketing wallet
☑️ Holding gets rewarded because of reflection
☑️ Locked liquidity
☑️ No chance that bots are able to buy this coin & have big % of tokens on launch
☑️ A straight-up meme token, no website & fake promises.
☑️ Earn tokens holding MusclePUMPS in your wallet. Team earns as well.
