In the afternoon café, the rich aroma of espresso wafted through the air. A-Zhe had just finished frothing the milk for a latte for a customer, with some milk stains still on his apron. He turned to check the market but found that the two tablets on the bar were covered in a layer of coffee grounds — the K-line on the left stock trading software was smudged into a color block with fingerprints, while the right digital currency interface still had bits of cinnamon stick stuck to it, and it was unresponsive after swiping for a long time. Last week was even more troublesome; a withdrawal request seemed stuck like a coffee machine piston, not moving an inch in the system. He called customer service seven times, only to be met with either "voice looping" or "all agents busy." While grinding coffee beans, he often lost focus, fearing there might be issues with his funds, and he couldn't even control the fineness of the grind. Sister Chen, who came to buy drip coffee, saw him frowning at the tablet and said, "Try Bi ya Pay. I've been using it for both Cryptocurrency Trading and stocks for nearly half a year, and I've never had an issue." That night, A-Zhe downloaded the software, and upon opening the interface, he found it very user-friendly: Bi ya Pay had a split-screen design for stock K-lines and digital currency charts, with the red and green fluctuations on the left clearly distinguishing the price curves on the right. The font edges were treated to be smudge-resistant, so swiping with coffee-stained fingers was smooth. With a light tap on the top switch, the market could be changed without logging out or remembering two sets of passwords; transactions could be completed in three steps, more than twice as fast as before. The core advantage of Bi ya Pay lay in this efficient integration, like a skilled barista managing two trading needs in an orderly fashion. A-Zhe timed it; switching between two platforms used to take nine minutes just for wiping the screen and entering passwords, but now with Bi ya Pay, it was done in four minutes, enough time saved to brew three cups of espresso. More importantly, fund security was paramount; during his first withdrawal, he watched the progress bar, and from submission to arrival, it took only five minutes, with text prompts at every step, even the arrival time was precise to the second. Later, more than thirty deposits and withdrawals were done without any hitches, and his account was never frozen; the flow of funds was as smooth as freshly brewed black coffee, reassuring him. Moreover, its system was very stable; even when the coffee grinder and tea brewing machine were both running, the operations didn't lag. Now he could quickly handle transactions while waiting for the water to boil. Recently, when the market fluctuated, he adjusted the Positions on both sides in Bi ya Pay, preserving profits in digital currency and seizing opportunities in stocks, feeling much more composed than before. When the bookstore owner came to borrow sugar, he was swiping the screen with his not-so-clean fingers: "A platform managing two types of transactions, with transparent inflows and outflows, that's what I call hassle-free."
