Have you encountered this before? I sold coins on Binance yesterday on this card, and then transferred two sums of money from another card to this card, and then used it to repay Wechat Micro Loan immediately. At that time, I forgot that I had to wait a while before I could use it. In this case, what materials does the bank require, especially whether it will require any evidence materials from the Binance seller? This is the first time I have encountered this. Can the big brother help me solve the problem?
