$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.

🔥 There is a war to be King. Whoever is the King commands the whole army and the taxes from it's subjects, 6% reflections, but the King holder will always have a target on their back. With every sell, the King gets richer and richer... but with every buy comes the threat of a new challenger. Do you have what it takes to rule? 🔥
🏁 The rules of the game. 🏁
▶️ If you make the biggest buy (in ETH) you will be the King for 30 minutes, and collect 6% of traded volume (in ETH) the same way marketing does.
Once 30 minutes is up, the counter will be reset and everyone will be able to compete again to be King.
▶️ If you sell any tokens at all at any point you will lose your kingdom.
▶️ If someone beats your record, they become the King.

* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means

* 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}.

ROGUE is a distributed network consisting of a blockchain ledger, native cryptocurrency and robust ecosystem of on-chain applications and services.
ROGUE ROGUE is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. ROGUE is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances.
ROGUE features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Americoin is a proven medium of commerce complementary to Bitcoin?

What is ROGUE
The vision of ROGUE is to build a decentralized, global digital defi ecosystem community that allows content to be freely transfer their money to one person to other & also apply for crypto loans for defi projects Infrastructure ROGUE will incentivize Defi creation and financial diversity and return the rights and value to its user. ROGUE will be a public protocol that not only carries yield farming value but is also crypto for your daily needs contributions Decentralized digital ROGUE system.
Smart Chain
Smart Chain is best described as a blockchain that runs in parallel to the Ethereum. Unlike Ethereum, ETHEREUM boasts smart contract functionality and compatibility with the Ethereum Virtual Machine EvM. The design goal here was to leave the high throughput of Ethereum intact while introducing smart contracts into its ecosystem. How Ethereum Blockchain achieves ~3 second block times with a Proof-of-Stake consensus algorithm. Specifically, it uses something called Proof of Staked Authority or PoSA, where participants stake ETH to become validators. If they propose a valid block, they’ll receive transaction fees from the transactions included in
Transaction
money transfers made from one person to another through an intermediary, typically referred to as a P2P payment application. p2p payments can be sent and received via mobile device or any home computer with access to the Internet, offering a convenient alternative to traditional payment methods. Through the p2p payment application, each individual’s account is linked to one or more of the user’s bank accounts. When a transaction occurs, the account balance in the application records the transaction and either sends or pulls money directly to the user’s bank account or stores it in the user’s account within the application.
Staking
Staking is the process of actively participating in transaction validation similar to mining on a proof-of-stake PoS blockchain. On these blockchains, anyone with a minimum-required balance of a specific cryptocurrency can validate transactions and earn Staking rewards. How does staking work When the minimum balance is met, a node deposits that amount of cryptocurrency into the network as a stake (similar to a security deposit). The size of a stake is directly proportional to the chances of that node being chosen to forge the next block. If the node successfully creates a block, the validator receives a reward, similar to how a miner is rewarded in proof of-work chains. Validators lose part of their stake if they double-sign or attempt to attack the network.
ROGUE Token (ROGUE)
ROGUE is a BEP20 fixed-supply token designed with an aggressive deflationary mechanism. Currently, ROGUE is only available on the Ethereum Smart Chain. At launch, a total supply of 100 000 ROGUE will be created and after this, no more ROGUE can ever be created.
Every ROGUE transaction will incur a 1% transaction fee. This fee will get deducted from each transaction, burned, and converted into ROGUE Reward (RGW). Effectively, every transaction will contribute to the reduction of the total supply of ROGUE.
ROGUE Reward (RGW)
RGW can only be created by the ROGUE smart contract. Every time a ROGUE transaction occurs, 1% of the total amount of the transaction will deducted, burned, and converted into RGW.
RGW will represent the holder's share in the ROGUE Protocol ecosystem. It will be used for the governance of the ecosystem and confer voting rights to the holder. RGW will also be the primary token for bootstrapping all future projects under the ROGUE Protocol ecosystem.
Main Features
ROGUE is designed with an aggressive deflationary mechanism with the aim of growing the value of the token as the project matures.
Fixed Supply
At launch, a total supply of 10000000 ROGUE will be created with 5000000 deposited and locked into the ROGUE Token Reserve. After this, no more ROGUE can ever be created.
No Presale
40% of the total supply of ROGUE will be provided as liquidity on UniSwap and burned. While 50% will be time-locked in the ROGUE Reserve.
Deflationary
Every ROGUE transfer will incur a 1% fee that gets burned. Effectively, every transaction will contribute to the reduction of the total supply of ROGUE.
Loyalty Reward
Every time a ROGUE transaction occurs, 1% of the total amount of the transaction will deducted, burned, and converted into RGW.
Timelock
There is a 15-day timelock delay on both the ROGUE and Reserve smart contracts. RGW holders can vote to implement some changes.
Community Governed
ROGUE and all subsequent project will be community governed project. As shareholders, RGW holders will have voting rights.

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 and all the clues came from Twitter
https://twitter.com/base58eth
Bless everyone
Total: 100,000,000
Burn: 42,000,000
Liquidity: 58 ETH
Max buy: 100,000
Max wallet: 500,000
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.
