In the glass cabinet of the dessert shop, the macaron's icing glimmers under the warm light. Sister Lin had just finished sprinkling cocoa powder on the mousse cake when the sugar dust on her fingertips smudged the mobile phone at the cash register — the K-line of the stock software on the left was obscured by sugar granules and turned into a dashed line, while the digital money interface on the right still had some cream stuck to it, making it difficult to see the numbers even after three swipes. The events of last week still made her uneasy; a withdrawal request felt like melted chocolate, lingering in the system with no updates. She had called customer service seven times, only to be met with either "voice navigation loop" or "all agents are busy". While baking cookies, she often stared blankly at the oven, even forgetting to soften the butter. Little Wu, who came to order a birthday cake, looked at the design and saw her sighing at her phone: "Try Bi ya Pay; I've been using it for both cryptocurrency trading and stock trading for almost a year without any issues." That evening, Sister Lin downloaded the app, and the login interface was a pleasant surprise: Bi ya Pay displayed stock and digital money charts on the same page. The red and green bar charts for stocks on the left were neatly arranged, while the line chart for digital money on the right showed clear trends, with text edges treated to prevent sticking, making it easy to swipe with her finger dusted with icing. The most convenient feature was the top switch button, allowing her to toggle between the two markets with a single tap, without needing to log out and back in or remember two sets of passwords, completing tasks in just ten steps from opening to operation. The benefits of Bi ya Pay went far beyond that. It acted like a thoughtful pastry chef, managing two types of trading needs efficiently. Sister Lin timed it; switching between two platforms used to take nine minutes just to wipe the screen and enter passwords, but now it took her only four minutes with Bi ya Pay, allowing her to bake two more trays of tart shells each day. More importantly, the safety of funds was paramount; she watched the progress bar during her first withdrawal, taking only five minutes from submission to arrival, with text prompts at each step, even the arrival time down to the minute. Later, after more than thirty deposits and withdrawals, there were no hitches regardless of the amount, and her account had never been frozen; fund movements were as smooth as whipped cream, providing peace of mind. Moreover, the system was stable; even when the shop's freezer and mixer started simultaneously, operations did not lag. Now, she could handle trades while waiting for the oven to preheat. Recently, during market fluctuations, she adjusted positions on both sides in Bi ya Pay simultaneously, securing profits in digital money and seizing opportunities in stocks, feeling much more composed than before. When the owner of the bubble tea shop came to borrow a piping bag, she was swiping the screen with fingers coated in chocolate sauce: "A single platform managing two types of trades, with transparency in money flow, that’s what I call peace of mind."
