Angel 👼
From the pool party, to splish splashing, we end up with the angel emoji.
✅ 1,000,000 Total Supply
✅ 15% LP Fee (party gets sent to creator wallet to buy back ETH)
✅ No buy limit
✅ 1 month liquidity lock
✅ No renounced ownership, no contract functions I could use to do anything malicious anyway.
When I renounce the owner wallet will be the dead address, so I won't be able to do buy backs.

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.

$BATU - THE PREMIER NFT MEME TOKEN !
Website: https://batu.finance
Telegram: t.me/BatuFinance
Twitter: twitter.com/BatuFinance
Batu’s ($BATU) mission is to bring fresh utility to the meme-token space, with a strong emphasis on creating exclusive, luxury NFT’s and art-offerings to crypto enthusiasts worldwide.
BATU has integrated the most advanced tokenomics in the space, creating a token that is designed to go up in value.
BATU has no sale limitations, and an innovative dynamic reflection tax rate which increases proportionate to the size of the sell.
TOKENOMICS:
Liquidity locked, ownership renounced
No pre-sale, no team wallets
1,000,000,000,000 token supply - 100% added to Uniswap liquidity pool
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.
A unique approach to resolving the huge dumps after long pumps that have plagued every NotInu fork
:) Shout-out to Musubi, Myobu, DonShiba developers for laying down the foundation of these awesome tokenomics :)

* ATTENTION!
*
* This code? IS NOT DESIGNED FOR ACTUAL USE.
*
* The author of this code really wishes you wouldn't send your ETH to it.
*
* No, seriously. It's probablly illegal anyway. So don't do it.
*
* Let me repeat that: Don't actually send money to this contract. You are
* likely breaking several local and national laws in doing so.
*
* This code is intended to educate. Nothing else. If you use it, expect S.W.A.T
* teams at your door. I wrote this code because I wanted to experiment
* with smart contracts, and I think code should be open source. So consider
* it public domain, No Rights Reserved. Participating in pyramid schemes
* is genuinely illegal so just don't even think about going beyond
* reading the code and understanding how it works.
*
* Seriously. I'm not kidding. It's probablly broken in some critical way anyway
* and will suck all your money out your wallet, install a virus on your computer
* sleep with your wife, kidnap your children and sell them into slavery,
* make you forget to file your taxes, and give you cancer.
*
* So.... tl;dr: This contract sucks, don't send money to it.
*
* What it does:
*
* It takes 50% of the ETH in it and buys tokens.
* It takes 50% of the ETH in it and pays back depositors.
* Depositors get in line and are paid out in order of deposit, plus the deposit
* percent.
* The tokens collect dividends, which in turn pay into the payout pool
* to be split 50/50.
*
* If your seeing this contract in it's initial configuration, it should be
* set to 200% (double deposits), and pointed at POTJ:
* 0xC28E860C9132D55A184F9af53FC85e90Aa3A0153
*
* But you should verify this for yourself.
*

*
* 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}
