Recently, everyone has been talking about "sandwich" and "arbitrage" as if it's easy money.

While I sip tea and browse the blockchain, I have only one feeling: what you think is an opportunity is often just others taking fees and slippage in smarter ways.
Others think that just by setting up a bot to copy trades, they can make profits, but the moment you click confirm, you might already be on someone else's waiting list... Especially now, with a bunch of testnet incentives and points speculation soaring, the mainnet's token issuance is still uncertain, but the on-chain sentiment has already been shaped.
Anyway, when I see a "guaranteed profit strategy," I first ask: where does this profit come from?
If the answer is "from people entering later," then it's probably not a role I want to play.
