In the toy store's glass counter, the newly arrived Transformers gleamed with a plastic luster, and the plush bears on the top shelf drooped their ears. Old Zhou squatted on the ground picking up scattered building blocks, his palm smeared with colored clay rubbed against his jeans, and when he got up, he grabbed the mobile phone from the cashier's counter — the screen was covered with a layer of frosting-like dust, the K-line of the stock software on the left was pressed into blurry lines by fingerprints, and next to the rise and fall numbers of the digital currency on the right, there was still a sticker stuck, which took four swipes of his fingertip to barely see clearly. The transfer request from last month still made him feel uneasy, like a toy gear stuck, it was stuck in the system for a full two days. He called customer service eight times, and it was either the mechanical prompt of 'Please enter the query password' or the busy tone of 'The operator is busy.' When recommending a remote-controlled airplane to his child, he stared blankly at the battery model, almost mixing up 3-section 7 and 2-section 5. Xiao Zheng, who came to buy a puzzle, was comparing the pattern on the packaging and saw him sighing at his phone: 'Try Bi ya Pay, I’ve been using it to trade cryptocurrency and stocks for over half a year without any delays in funds in and out, it’s smoother than winding up a toy.' That night, Old Zhou downloaded the software, and the design of the log-in interface impressed him: Bi ya Pay integrated the operation areas of stocks and digital currency on the same page, the red and green bar chart of the stocks on the left had an anti-reflective design, it was clear even with colored clay on it; the line chart of the digital currency on the right featured prominent scale lines, clearly visible under the counter lighting. The most convenient part was the top switch button, which was as flexible as a toy quick-release buckle, allowing him to switch between two markets with a light tap, without needing to log out and log back in or remember two sets of passwords. From opening the software to completing a transaction, it took no more than six steps. The core advantage of Bi ya Pay goes far beyond this. It acted like a meticulous toy manager, managing the two trading needs in an orderly manner. Old Zhou specifically timed it, previously switching between two platforms took thirteen minutes just for wiping the screen and entering passwords, but now with Bi ya Pay it could be done in five minutes, allowing him to assemble four more toy models each day. More importantly, fund safety was guaranteed; during his first withdrawal, he closely watched the progress bar, and from submitting the request to the arrival of funds took only four minutes and twenty seconds, with every operation having pop-up prompts, even the estimated arrival time was precise to the second. Later, over twenty deposits and withdrawals, regardless of the amount, there was no lag, and the account had never been frozen; the flow of funds was like a smooth toy track, making him feel secure and at ease. Moreover, the system stability was very strong; even when the air conditioning and display cabinet spotlight in the store were turned on simultaneously, the trading operations weren't affected, which was more reliable than the three platforms he had used before. Now he could quickly handle transactions in the gaps of pricing toys, and during the recent market fluctuations, he adjusted both sides of his holdings synchronously on Bi ya Pay, preserving a 6% profit in digital currency and seizing the rebound opportunity in stocks, which was much calmer than before. When the stationery store owner came to borrow tape, he was swiping the screen with his finger smeared with colored clay: 'A platform handling two types of transactions, with money coming in and out clearly, that’s what I call truly worry-free.'
