Explanation
Platforms monitor transactions and report unusual patterns. That explains why a large deposit or a withdrawal to an unknown address can trigger extra questions.
Why these rules exist
Anti-money-laundering law requires financial institutions to know their customer, monitor transactions and report unusual patterns to a national unit (CFI in Belgium, FIU in the Netherlands). Crypto sat outside that framework for years; since the fifth AML directive and MiCA the same duties apply to crypto service providers.
What you notice
Questions about the origin of funds, temporarily blocked withdrawals after an unusual transaction, and extra scrutiny when you deposit from or withdraw to an address linked to a mixer or sanctioned platform. A report is not an accusation, but unblocking an account can take days to weeks.
Key takeaways
- The same duties as at banks.
- Reports are made without your knowledge.
- Document where your money comes from.
