(30)An appropriate risk-based approach requires obliged entities to identify the inherent risks of money laundering and terrorist financing as well as the risks of non-implementation or evasion of targeted financial sanctions that they face by virtue of their business in order to mitigate them effectively and to ensure that their policies, procedures and internal controls are appropriate to address those inherent risks. In doing so, obliged entities should take into account the characteristics of their customers, the products, services or transactions offered, including, for crypto-asset service providers, transactions with self-hosted addresses, the countries or geographical areas concerned and the distribution channels used. In light of the evolving nature of risks, such risk assessment should be regularly updated.
