Hello, when depositing fiat currency, you need to provide proof of legitimate income.
Common proof materials include:
- Employment contract: showing your employment relationship and source of income.
- Tax certificate: such as recent tax returns, proving that your income has been taxed according to law.
- Screenshot of brokerage withdrawal records: showing records of funds withdrawn from your securities account.
Please provide the corresponding proof materials based on your actual situation to ensure the legitimacy of the source of funds.
