NLC [Nelore Coin] Token

The First Agricultural token that gives rewards based on real profit.
NELORE COIN is an agricultural business token with multiple farms under management focusing on COW production in Brazil that gives rewards based on real profit.
The transaction tax goes to a Treasury account where the money is invested on buying or renting farms in Brazil. This way it creates an intrinsic value that should uphold bear markets and grow with bull markets.
The selection of farms is very important so it can be the most profitable for the money invested.
Those farms produce a profit which is used to buy NLCs from the Liquidity Pool. Coin buying usually happens every month and in the worst case 2 months.
Since the start of the project, NELORE COIN already bought 2 farms in Brazil capable of producing 20.000 COWs with a total of 20 hectares of land.
The team at NELORE COIN is composed of Agricultural experts with more than 20 years of experience. It was founded by CEO Marcos Rodrigo, Vice President Carlos Junior and CFO Emerson Muller. Now the team consists of more than 10 people and are in the process of hiring several more.
Brazil is the biggest exporter of Agricultural products and NELORE COIN is the first real agricultural token based on Brazil with a real company already created.
In the future, it aims to be the biggest farm manager in the world combining WEB3 features into a very old-fashioned sector of the global economy.
With blockchain technology it aims to tokenize its NELORE COWS through an internal NFT system and create a Marketplace for real-time transactions of multiple Agricultural products. And it aims to record immutable and trusted data onto the blockchain such as the production, distribution, and sales history of every product.
Other than that it aims to create a speculative investment market on agricultural products in Brazil, partnering with the biggest farmers in the country. Where users will be able to speculate on prices of Cows, Seeds, Oxes, Chicken a

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.
Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract has 12% buy tax and 15% sell tax.
Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.
Token is deployed only at one blockchain
Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.
Young tokens have high risks of scam / price dump / death
Token has no active CoinGecko listing / rank
Token has no active CoinMarketCap listing / rank
