I opened an account in Singapore and also in Hong Kong. They do require proof of address, but their disclosure requirements for asset size are very restrained. For most private banks and institutions below, as long as you provide a deposit certificate with a qualified investor threshold of over 1 million US dollars, you can increase the deposit size to a certain extent by default. The specific data is unknown, but below 3 million US dollars is not a problem. If there are any questions about the subsequent deposit and withdrawal requirements, they will explain the deposit and withdrawal requirements. If the SingPass verification is passed, usually answering a few questions can result in a limit of several hundred thousand, which is a basic trust for legitimate users. The problem with OKX is that regardless of the user verification method or the size of the user's transaction, it directly conducts a private level source review of each user's asset source, and the proof of asset source is extremely strict. The given range of extremely narrow source single selection makes it difficult for users to choose. How many people have income from a single source? If the proof submitted for the first time does not meet the requirements, and then you have to ask how it came about for the second time, if it is different from what was said for the first time, you will say it is different but not explain where it is different, which feels like endless mental punishment. You don't know how large a transaction I want to make, but I need such a detailed asset report, which is unacceptable. At this point, I can only politely say goodbye and wish to delete the app.
