Seeing that today is arguing about the issue of "proof of funds". I happened to have it a while ago. One day, when you log in to the exchange, a prompt suddenly pops up on the homepage: you need to submit a proof of the source of funds within the specified time, otherwise the use of the function will be restricted. I clicked in and followed the prompts, and submitted a screenshot with confidence, but the result was directly rejected. I changed the option again, submitted again, and it was still rejected. Repeated submissions three times, all failed. To be honest, my first feeling at that moment was that the experience was very poor and quite unpleasant. I wonder if this platform doesn't work. Contact customer service to try to communicate, and the feedback is relatively limited. After calming down, I began to study carefully and found that the essential problem was actually in the "screenshot". Mobile phone screenshots are not recognized, especially information without a seal or official letterhead, which will basically be rejected. I later remembered that I could issue income and tax certificates from the "Personal Income Tax App". But the embarrassing thing is that the real name of the account is my wife's, and she has no job and no tax records...... So I changed the way, chose "unemployed" and "investment income" in the source of funds, and then went to Alipay to call up her fund transaction flow in the past five years, taking the [asset certificate] path, and the operation steps were: Open Alipay Fund → Transaction History → Customer Service in the upper right corner → Find "Asset Proof" → After entering, select "Wealth Management Transaction" and set the time (I customized it is 5 years→ The system will automatically generate a stamped PDF file and send it to the mailbox in seconds. I downloaded it, submitted it, uploaded it, and this review passed ✅ quickly A few lessons and suggestions to sum up: In fact, as long as it is a real-name account and a "person with traces of life" has a real source of funds, it is not difficult to obtain the submitted materials, the key is: 1 Must be an official document issued by the trading platform/financial institution 2 Include real name, transaction details, institution letterhead, timestamp, and seal 3. Try to avoid uploading ordinary screenshots, especially images that lack headhead, no stamp, and no clear source of information, which will basically not pass the review Some of the channels that can be used to issue proof of funds include: 1 Bank Statement 2 Transaction details of funds/securities platforms 3 Payroll bill or tax payment certificate 4 Investment account withdrawal record (with transaction hash and platform seal) A little advice for exchanges: This process is actually not complicated, but many people encounter it for the first time, and it is easy to misunderstand it as "just take a screenshot and hand it in", and the result is rejected several times, and the emotions are easy to get up, especially in the stage when the market is downturn and is already losing money and upset. It is recommended that the platform attach "correct examples" and "failed examples" to the application page, and clearly list the "conditions for valid documents", which can greatly reduce the misoperation and customer service burden. Overall: Although this operation process was quite unpleasant at first, in retrospect, it was also an exercise in asset compliance. As long as the account real-name is compliant and the information is complete, it can be successfully passed in the end. After writing it, I also hope that the platform can be more detailed in the experience, otherwise many people will really think "what a moth again" at the first time. @star_okx @okx @okxchinese
