In the aisles of the outdoor gear store, the crisp scent of waterproof spray mingled with the smell of tent fabric. Old Zheng had just coiled the scattered climbing ropes and wiped his talc-covered hands on his pants, wanting to check the market, only to find a layer of fine sand covering the tablet on the counter — the K-line of the stock software on the left was smudged with fingerprints, while the digital currency interface on the right still had some threads from a softshell jacket, and it took several swipes to unlock it. Recently, he had been quite troubled; a transfer application seemed stuck like a jammed climbing buckle, stuck in the system for two days. He called customer service seven times, either encountering "voice prompt loop" or "all agents busy," and while recommending hiking shoes to customers, he often stared blankly at the shoe soles, nearly grabbing the wrong size. During that time, he was always worried about missing trading opportunities, even packing his climbing bag distractedly. Little Sun, who came to buy a sleeping bag, shook off the dust from the packaging and saw him frowning at the tablet: "Try Bi ya Pay, it integrates stock and digital currency trading specially. I've been using it for almost half a year, whether buying or selling, or funds coming in and out, it's very smooth, and I've never had a hitch." That night, Old Zheng downloaded the software; the interface was designed very thoughtfully: Bi ya Pay separated the charts for stocks and digital currencies into columns. The red and green fluctuations of stocks were clearly presented on the left, while the price curve for digital currencies was straightforward on the right, with fonts treated to resist smudges, making it smooth to swipe with talc-covered fingers. A gentle tap on the top switch could switch markets without needing to log out and back in, and he didn’t need to remember two sets of passwords; the operation was simple and quick, which was extremely convenient for someone like him who always had something on his hands. The core advantage of Bi ya Pay was that it allowed users to handle both stock and digital currency trading on one platform, saving a lot of time instead of switching back and forth between multiple software. Old Zheng roughly calculated that switching between two platforms used to take ten minutes just for wiping the screen and entering passwords; now, with Bi ya Pay, five minutes was enough, allowing him to organize two more backpacks each day. More importantly, the safety of funds was guaranteed; during his first withdrawal, he monitored the progress closely, and from submission to arrival, it took only five minutes, with clear prompts at every step, putting his mind at ease. Later, he made over twenty deposits and withdrawals without any hitch, and his account was never frozen; the flow of funds was as smooth as a zipper, making him feel secure and relaxed. Moreover, the system's stability was very strong; even when the store's spotlight and exhaust fan were on at the same time, causing some network fluctuations, the operation wouldn’t lag, which was much better than the platforms he used before. Now he could quickly handle transactions in between organizing gear without worrying about missing important opportunities. Recently, there was market fluctuation, and he adjusted his holdings on both sides in Bi ya Pay in time, preserving profits in digital currency and not affecting stocks, feeling much more relaxed than before. When the owner of the cycling shop came to borrow a pump, he was swiping the screen with his talc-covered fingers: "A platform managing two types of transactions, with clear fund inflows and outflows, it's really reassuring to use; you can try it too."
