I have personally witnessed the shift from technology to the marketplace.

This afternoon, I went grocery shopping and used my phone to scan and pay. When checking out, the shop owner stared at my screen for a few seconds and then asked me what this new payment method was. I told her it was on-chain payment, and she nodded, looking a bit confused but seeming to think it was impressive.

If this scene had happened three or four years ago, I couldn't have imagined it. Back then, you had to find the merchant, compare exchange rates, and worry about encountering black U or counterfeit bills. The process was complicated and required research in advance. Now? Take out your phone, scan, and the money is directly transferred. It's that simple.

This is the true real-world application of cryptocurrency — not promises in whitepapers, not empty talk on forums, but a tangible tool that can be used to pay for groceries. From OTC over-the-counter trades to direct on-chain payments, this shift reflects the entire ecosystem moving from speculation to practicality.

I've now become very comfortable with this payment method and can handle various scenarios. Once you get used to this convenience, there's no going back.
