Once I encountered some issues while trading, and with a try-and-see attitude, I reached out to customer service. To my surprise, someone replied within a minute! It was a live customer service representative, and their attitude was super nice. Later I learned that they are available online 24/7, so no matter what time you ask, they can basically respond in a timely manner. Moreover, they support not only Chinese but also English, Indonesian, and Vietnamese, making it very smooth for overseas friends to use. Previously, their system had a bug, and they proactively compensated users with several million dollars, which shows they are quite responsible.
