6. 個人經驗與觀點
「你以為自己好精明，特登 Check 咗匯率先換錢。但當你見到銀行個匯率同你 Check 嘅差 2%，你就會發現——你睇到嘅匯率從來都唔係你真係攞到嘅匯率。銀行食咗差價，找換店食咗差價，連 PayPal 都食埋一份。匯率換算器畀你嘅只係『市場價』，而銀行俾你嘅係『佢想俾你嘅價』。呢個世界嘅殘酷在於：你以為自己掌握咗資訊，但其實你只係睇到佢哋想你睇到嘅嘢。」

6. Personal Insights & Expert Advice
"You think you're smart—you checked the exchange rate before exchanging money. But when you see the bank's rate is 2% worse than what you checked, you realize—the rate you see is never the rate you get. Banks take a cut, currency exchanges take a cut, even PayPal takes a cut. A currency converter gives you the 'market rate'—but the bank gives you the rate they want you to have. The cruel truth is: you think you're informed, but you're only seeing what they want you to see."
