MiCA Recital (4) — preamble

(4) Other crypto-assets, however, fall outside of the scope of Union legislative acts on financial services. At present, there are no rules, other than those in respect of anti-money laundering, for the provision of services related to such unregulated crypto-assets, including for the operation of trading platforms for crypto-assets, the exchange of cryptoassets for funds or other crypto-assets, and providing custody and administration of crypto-assets on behalf of clients.  The absence of such rules leaves holders of those crypto-assets exposed to risks, in particular in fields not covered by consumer protection rules. The absence of such rules can also result in substantial risks to market integrity, including in terms of market abuse as well as in terms of financial crime. To address those risks, some Member States have put in place specific rules for all, or a subset of, crypto-assets that fall outside the scope of Union legislative acts on financial services, and other Member States are considering whether to legislate in the field of crypto-assets.
