1: One machine, one account
2: Use the entire flow, and do not connect to public WiFi during the process (even a single connection will trigger risk control)
3: Accounts cannot transfer internally, and other addresses brought over cannot be the same; multiple addresses must be used for multiple accounts (for example, if you withdraw from one Binance address to multiple BG accounts, it will trigger risk control)
If these three points are satisfied, there should be no issues; none of my three accounts have triggered risk control.
