$BTC #Transaction Fee Revealed

In front of the bank counter, Old Zhang clutched the crumpled remittance slip, his fingers trembling slightly. The fee section read "2%"; he calculated it three times, and it was still thirty yuan more than last year. The financial manager at the next window was excitedly introducing a "Supreme VIP Fee Waiver Package" to a customer in a suit, the reflection on the glass made Old Zhang squint.

Back home, he dug out the remittance records sent by his son from abroad, discovering that each transaction had been charged twice - once here and once there. During a video call that night, his son smiled and said, "Dad, now we use blockchain for transfers; the fees are just a few dimes." But Old Zhang stared at the complex QR code on his phone, ultimately just sighing. The next day, he took cash and spent two hours on the bus to his relative's house in the suburbs, personally stuffing the tuition fees into his nephew's backpack. On the return trip, the bus's QR code scanner beeped and deducted fifty cents from him as a payment fee.
