AML compliance is not a one-time event but a continuous process. The frequency of checks depends on the risk profile. For a high-risk customer or wallet, continuous monitoring is essential. For exchanges, every incoming transaction should be screened in real-time. For an individual investor, performing a check on every new counterparty is a prudent practice. Businesses should also periodically re-screen their entire user base as new intelligence emerges. Establishing a risk-based schedule for checks is a key part of a compliance policy. You can start with a free aml check to establish a baseline risk level.
