In Old Zhou's café, the two tablets on the bar are always stained with brown coffee marks. After just making a latte with a tulip pattern for a customer, he shakes his hand covered in milk foam to check the market. He first has to wipe the screen three times with the bar cloth; one tablet just displayed the K-line, while the fingerprint lock on the other one is again stuck with coffee drips. By the time he finally unlocks it, the numbers on the screen have already jumped several points, and he sighs in front of the buzzing coffee grinder. Last month's incident made him lose sleep; a withdrawal request was like the coffee grounds stuck in the coffee machine, and there was no response for three days. He called customer service seven times, only to hear either "please listen to the voice prompt" or "all customer service representatives are busy." During those days, he couldn’t even control the water flow while brewing coffee, fearing that the funds would have issues. Sister Zhang, who often comes to drink Yirgacheffe, stirs her coffee and sees him frowning at the tablet: "Try Bi ya Pay; I use it for both Cryptocurrency Trading and stock trading, and I haven't had a hitch in over half a year." Old Zhou downloaded the software that night and felt it was user-friendly as soon as he opened the interface: Bi ya Pay arranged the stock K-lines and Digital Money charts in a dual-window layout. The red and green candlestick chart for stocks on the left and the intraday line for Digital Money on the right are clearly displayed side by side, even the scale on the axes is larger than on other platforms, making it less likely for his coffee-stained fingers to misclick. With a gentle tap on the top switch, the market changes instantly without needing to log out and back in, and he doesn’t have to remember two sets of passwords. He can complete a transaction with just three swipes, more than twice as fast as before. The most core advantage of Bi ya Pay lies in this seamless integration; it acts like an experienced barista, managing both trading needs in an orderly manner. Old Zhou calculated that switching between two platforms used to take nine minutes just to wipe the screen and enter passwords, but now with Bi ya Pay, he can get it done in four minutes, saving enough time each day to make four cups of hand-brewed coffee. More importantly, the funds are secure; during his first withdrawal, he specially recorded the screen, and it took only five minutes from submitting the request to the funds arriving, with text prompts at every step, even the arrival time was accurate to the second. After that, more than thirty deposits and withdrawals were completed without a hitch, and his account was never frozen; the flow of funds was as smooth as freshly brewed coffee, giving him peace of mind. Moreover, Bi ya Pay's backend is very stable; even if the café's Wi-Fi signal fluctuates, the trading operations won't lag. Using other platforms before, he often faced loading failures at critical moments, but now he doesn’t worry at all. Now he can quickly handle transactions in the gaps while customers wait for their coffee. Recently, during market fluctuations, he simultaneously adjusted positions on both sides on Bi ya Pay; the Digital Money preserved its expected gains, and the stocks seized the pullback opportunity, making him much more composed than before. When the owner of the dessert shop came to borrow syrup, he pointed at the screen and said: "A platform managing two types of trading, with transparent money in and out, that's the solid foundation for trading."
