Recently, watching those on-chain sandwiches + arbitrage, it really feels like a street vendor: you think you've found a bargain, but in reality, they've already factored the "travel expenses" into the price. To put it simply, when an ordinary person jumps in, many times they're just paying others' transaction fees and gas money... Now, before I place an order, I pause for two seconds: am I catching an opportunity, or am I just serving as a background for the bots?

What's even more outrageous is that recently, hardware wallets are out of stock, and phishing links are everywhere. People are fully aware of security but still get itchy to click. Anyway, I treat links as if they were red envelopes sent by strangers—don't click; if I need to act, I try to use limit orders and small amounts to test the waters. If I miss out, I miss out. If the fragments don't shine, don't force it.
