Last November 10th, I transferred 150,000 to the account through Alipay in a single transaction with no issues whatsoever, and the speed was quite fast. However, recently, with the same operation, when I deposited 200,000, Alipay froze the transaction for 7 days. I was a bit surprised, but fortunately subsequent deposits could still go through—it's just that this signal is quite interesting. My strategy changed after that—under non-essential circumstances, I basically won't make large withdrawals anymore. It seems the environment for cryptocurrency deposits and withdrawals has indeed been changing, so I need to be more cautious about it.
