We're coming for all the ERC20's on Ethereum
We have a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, as a result; $SHIBWORLD is designed to reward holders and discourage dumping.
1. Bot and whale manipulation prevention: Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will go directly to Uniswap for trading.
3. No presale or team wallets allocated with tokens that can dump on the community.
Token Information:
1. 1,000,000,000,000 Total Supply, but we're burning 10% of this imemdiately to create a super deflationary mechanism within the tokenomics!
3. Developer provides LP and it's locked with Team.Finance
4. We have made the fairest possible launch for everyone and pre-announced, so there is no early secret buyers!
5. 0,6% transaction limit on launch - You can only buy 6000000000 $SHIBWORLD until it's lifted
6. Buy limit lifted to 1% of the supply 5 minutes after launch, then the ownership of the token is immediately renounced
7. Sells limited to 3% of the Liquidity Pool, <3% price impact - Anti dump mechanism
8. Sell cooldown increases on consecutive sells, 5 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 6% redistribution to holders on the first sell, increases 2x, 3x, 4x, 5x on consecutive sells
11. This redistribution mechanism works as expected above and benefits the holders much more than sellers!

//// The eFIAT protocol relies on Proof of Burn, meaning any eUSD can only
//// be created by burning Ether at market value. Because Ether is denominated also
//// in USD value, the burning of Ether can be regarded as burning of US Dollars,
//// where Ether serves only as the medium of value transfer and verifiable proof
//// that actual value has ben permanently migrated and not replicated. This means
//// eUSD can never be used to redeem any Ether burned in the eUSD creation process!

* Last Man Standing is an Erc20 battle royale game.
* 5% of tokens will be burned on every transaction, similar to a rebase, these coins are burned permanently.
* Small limited 10,000 supply(NO DECIMALS). Minimum 1 LMS burned per transaction. Maximum 10,000 transactions possible.
* As supply shrinks, the price increases, but when will you take profit?
* Upon reaching 1 supply, the coin can't be sold.
* Can you avoid being the last man standing?

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

Once the hour is finished, the counter will be reset and everyone will be able to compete again for the Diamond.

*
* 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}
