The bait
A fake buyer advertises an unusually high rate and sends a convincing payment image to create urgency.
The independent check
Open your bank app directly, confirm available balance and reference, then compare sender identity with the trade record.
The evidence chain
Keep the original screenshot, chat export, claimed reference, account details, and exact time.
Official and primary sources
