A beginner asked me about this recently, so I figured I’d write it down.
Sandwich trading: A bot spots a large buy order in the public mempool, buys before it, then sells after it.
On-chain transactions are generally visible to everyone before they’re bundled into a block. Whoever can determine the order of transactions has a chance to profit from it.
For context, $ETH is quoted at 2507.01, up 0.84% over 24 hours.
If you find this useful, save it so you can come back to it later.

Just sharing some thoughts—win or lose, you’re responsible for your own trades.
