HIDDEN GAME IN CRYPTO – HOW MEV BOTS MANIPULATE YOUR TRADES

HIDDEN GAME IN CRYPTO – HOW MEV BOTS MANIPULATE YOUR TRADES

Many crypto traders lose money without even knowing why! This happens because of MEV bots and sandwich attacks—a technical strategy used to exploit your trades on decentralized exchanges (DEX).

Let me break it down clearly for you!!

What is MEV (Maximal Extractable Value)?

MEV refers to the profit that validators, miners, or trading bots can extract by:

• Inserting (Placing a trade in between to make profit),
• Reordering (Changing the trade order to benefit the bot),
• Censoring (Blocking some trades to protect bot profits).

In simple terms, when you place a trade on a DEX (like Uniswap), before it gets confirmed, it goes into a space called the mempool, where everyone can see it (including your order).
MEV bots monitor your order and try to profit from it before it gets executed!

One major method MEV bots use is called the SANDWICH ATTACK. Here's how it works:

1️⃣ For example, you place an order to buy a token (say SHIBA) with $1,000 on Uniswap.
2️⃣ A bot sees your order in the mempool and quickly places its own buy order before yours (this is called front-running).
3️⃣ Because the bot bought the token first, the price of SHIBA slightly increases.
4️⃣ Now, your trade executes at a higher price than expected—so you get fewer tokens than you anticipated.
5️⃣ The bot instantly sells the SHIBA it bought at this higher price (called back-running) and easily makes a profit.

💡 You lose money, and the bot makes a profit!

A real-life example:

Let’s say you go to the market to buy baskets of tomatoes, and the price is ₦200 per basket.
You tell the seller, “I want to buy 10 baskets.”

But before the seller gives them to you, a smart guy (the bot) overhears your request and quickly buys all the tomatoes at ₦200 per basket.

Then he comes back and tells you:
“Sorry, the price just went up. Now it's ₦250 per basket if you still want them.”

Since you need the tomatoes, you have no choice but to pay the higher price. After you buy, the guy sells the rest of his tomatoes at the new, higher price and makes a profit.

That is exactly how a sandwich attack works in crypto!

HOW TO PROTECT YOURSELF FROM MEV BOTS

✅ Use Private Transactions – Some wallets and decentralized exchanges have MEV protection that hides your trades from bots. Examples: 1inch wallet, CowSwap, Ethan DSS.
✅ Use Limit Orders – Instead of buying at market price, set the price you want to buy at.
✅ Trade in Smaller Amounts – Large orders attract MEV bots, but smaller orders usually go unnoticed.

Note:
MEV bots are not real traders—they are bots created by skilled developers to manipulate markets.
This is known as game theory in crypto, where super-fast bots are able to profit off of ordinary traders.
