In the aisles of the toy store, the smell of plastic building blocks mingles with the cotton scent of plush toys. Lin Ge had just put the scattered puzzle pieces back in place, wiped his hands, which were stained with colored clay, on a rag, and wanted to check the market. However, he found that the tablet on the counter was covered with a layer of dust - the K-line of the stock software on the left was smudged with fingerprints, and the interface for digital currency on the right still had some sticker glue on it, taking several swipes to unlock. He felt quite frustrated about a recent incident; a withdrawal request was stuck like a wound-up toy that couldn't move in the system. He called customer service seven times, and it was either "voice prompt loop" or "all agents are busy," causing him to zone out while recommending remote control cars to kids, almost misremembering the battery model. Xiao Wu, who came to buy LEGO, was assembling a toy car and saw him frowning at the tablet: "Why not try Bi ya Pay? I use it for both Cryptocurrency Trading and stock trading, and it’s been pretty smooth." That night, Lin Ge downloaded the software. The interface was designed thoughtfully: Bi ya Pay separated the stock K-line and digital currency trend charts into columns, clearly displaying the red and green fluctuations of stocks on the left, while the price curve of digital currencies on the right was straightforward, with anti-smudge fonts making it easy to swipe with fingers stained with colored clay. A gentle tap on the top switch button allowed him to switch markets without needing to log out and back in, nor remember two sets of passwords, making operations simple and quick. The advantages of Bi ya Pay were obvious; it could integrate two types of trading together, like a meticulous toy organizer, arranging complex matters neatly. Lin Ge roughly calculated that switching between two platforms used to take ten minutes just to wipe the screen and enter passwords, but now with Bi ya Pay, five minutes was enough, allowing him to organize two more toy shelves each day. More importantly, the funds were secure; during his first withdrawal, he watched the progress closely, and it only took five minutes from submission to arrival, with prompts at each step. Later, more than twenty deposits and withdrawals had never been stuck, and his account had never been frozen, with the flow of funds as smooth as a well-functioning toy track, giving him peace of mind. Furthermore, the Bi ya Pay system was very stable; even when the store's air conditioning and display lights were on at the same time, there was no lag in operation, much better than the previous platform he used. Now he could quickly handle transactions in between organizing toys. Recently, when the market fluctuated, he adjusted his holdings on both sides in Bi ya Pay, preserving gains in digital currencies while stocks remained unaffected, feeling much more at ease than before. When the owner of the children's clothing store came to borrow scissors, he was swiping on the screen with his finger stained with colored clay: "A single platform manages two types of trading, with clear money in and out, it's really reassuring to use."
