MiCA and Bitcoin: What the EU's Crypto-Asset Regulation Covers and What It Leaves Out

Yes, but mainly to the businesses around it. MiCA, the EU's Markets in Crypto-Assets Regulation (Regulation (EU) 2023/1114), treats Bitcoin as a crypto-asset. As of October 26, 2026, any firm providing Bitcoin services to clients in the EU needs a MiCA authorization, or, for banks and certain other financial firms, permission under Article 60.

Bitcoin itself has no identifiable issuer, so recital 22 places it outside Titles II, III and IV, which include MiCA's rules on public offers. Individuals holding their own keys are not regulated by MiCA, and recital 83 excludes non-custodial wallet providers from its scope.

MiCA is the EU regulation that sets common rules for crypto-assets and the firms that serve their users. Its full title is the Regulation on markets in crypto-assets, Regulation (EU) 2023/1114. The European Securities and Markets Authority (ESMA) describes it on its MiCA page as uniform EU market rules for "crypto-assets that are not currently regulated by existing financial services legislation."

In stages. Under Article 149 of MiCA, the Regulation entered into force on the twentieth day after its publication. Titles III and IV have applied from June 30, 2024, and the rest of the Regulation from December 30, 2024. A short list of provisions has applied since June 29, 2023.

Yes. Article 3(1)(5) of MiCA defines a crypto-asset as "a digital representation of a value or of a right that is able to be transferred and stored electronically using distributed ledger technology or similar technology." Bitcoin fits that definition.

No identifiable one. Bitcoin's founding document, "Bitcoin: A Peer-to-Peer Electronic Cash System" by Satoshi Nakamoto, explains in Section 6 that "the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block." That, it says, "provides a way to initially distribute coins into circulation, since there is no central authority to issue them."

Recital 22 of MiCA addresses exactly this case: "Where crypto-assets have no identifiable issuer, they should not fall within the scope of Title II, III or IV." Title II is the part of MiCA that governs offers to the public of crypto-assets other than asset-referenced tokens and e-money tokens.

No. Article 4(3) of MiCA states that Title II, the rules on offers to the public of crypto-assets other than asset-referenced tokens and e-money tokens, does not apply where "the crypto-asset is automatically created as a reward for the maintenance of the distributed ledger or the validation of transactions."

The Bitcoin white paper describes new coins as created in each block for its creator, as "an incentive for nodes to support the network." Recital 26 of MiCA describes the same exemption for tokens "automatically created as a reward for the maintenance of a distributed ledger or the validation of transactions."

Crypto-asset service providers. Article 3(1)(15) of MiCA defines a crypto-asset service provider as "a legal person or other undertaking whose occupation or business is the provision of one or more crypto-asset services to clients on a professional basis."

Article 3(1)(16) lists the crypto-asset services. They include:

Recital 22 confirms that providers offering these services for crypto-assets without an issuer "should, however, be covered." In practice, an exchange, broker or custodian serving EU clients in Bitcoin falls under MiCA even though Bitcoin itself has no issuer.

Yes. Article 59(1) of MiCA provides that "a person shall not provide crypto-asset services, within the Union, unless that person is" either:

Once authorized, a provider can serve clients across the EU. Under Article 59(7), providers "shall be allowed to provide crypto-asset services throughout the Union" and those working cross-border "shall not be required to have a physical presence in the territory of a host Member State."

Yes. Article 143(3) of MiCA allowed firms that "provided their services in accordance with applicable law before 30 December 2024" to continue "until 1 July 2026 or until they are granted or refused an authorisation pursuant to Article 63, whichever is sooner." Member States could also refuse the transitional regime or shorten it.

So the longest possible transition ended on July 1, 2026.

Firms already authorized under national law had a shortcut. Under Article 143(6), Member States could apply a simplified authorization procedure to their applications submitted between December 30, 2024 and July 1, 2026, while still checking compliance with key MiCA requirements before granting authorization.

ESMA's MiCA page notes that during this phase MiCA and existing national regimes could coexist, which it says may lead to uneven consumer protection, and that it works to promote supervisory convergence. In its statement of December 4, 2025 (ESMA75-113276571-1631), ESMA said that firms still operating after the transitional period "are not guaranteed to be authorised under MiCA." It asked them to have orderly wind-down plans that avoid "undue economic harm to their clients."

ESMA's example of such a plan is organizing "the transfer of the crypto-assets held for the clients to another authorised CASP." The same statement points investors to the ESMA Interim MiCA Register to check whether their provider is authorized.

MiCA requires segregation and sets liability for losses. Under Article 75(7) of MiCA, a custodian "shall segregate holdings of crypto-assets on behalf of their clients from their own holdings." On the distributed ledger, client crypto-assets must be "held separately" from the provider's own.

The same paragraph requires custodied crypto-assets to be "legally segregated" from the provider's estate, "so that creditors of the crypto-asset service provider have no recourse to crypto-assets held in custody," in particular "in the event of insolvency."

Under Article 75(8), the custodian is liable "for the loss of any crypto-assets or of the means of access to the crypto-assets as a result of an incident that is attributable to them." That liability is "capped at the market value of the crypto-asset that was lost, at the time the loss occurred."

Incidents not attributable to the custodian are excluded. The text gives as an example "a problem inherent in the operation of the distributed ledger that the crypto-asset service provider does not control."

Every custody relationship needs a written agreement. Under Article 75(1), it must cover at least the custody policy, the security systems used, the fees and the applicable law.

They cover any crypto-asset admitted to trading. Under Article 86(1) of MiCA, the market abuse title "shall apply to acts carried out by any person concerning crypto-assets that are admitted to trading or in respect of which a request for admission to trading has been made."

Article 86(2) extends it to "any transaction, order or behaviour" concerning those crypto-assets, "irrespective of whether such transaction, order or behaviour takes place on a trading platform." The rules apply to "any person," not only to licensed firms.

No. MiCA regulates crypto-asset services provided "to clients on a professional basis," under Article 3(1)(15). Holding your own Bitcoin with your own keys is not a service provided to anyone.

The makers of the tools are outside it too. Recital 83 of MiCA states: "Hardware or software providers of non-custodial wallets should not fall within the scope of this Regulation."

MiCA is not the only EU rule that touches self-custody, though. The EU's Transfer of Funds Regulation, Regulation (EU) 2023/1113, borrows MiCA's definition of crypto-asset in its Article 3(14) and governs what providers collect when Bitcoin moves to or from a self-hosted address.

The rules point to a few concrete checks:

Yes, through the firms that serve Bitcoin users. MiCA treats Bitcoin as a crypto-asset, and anyone providing Bitcoin services to EU clients needs authorization. Because Bitcoin has no identifiable issuer, recital 22 keeps it outside MiCA's issuer and offer rules in Titles II, III and IV.

No. Recital 22 of MiCA states that crypto-assets with no identifiable issuer should not fall within Titles II, III or IV. Article 4(3) also exempts crypto-assets "automatically created as a reward for the maintenance of the distributed ledger or the validation of transactions" from the offer rules in Title II.

No. MiCA requires authorization only for crypto-asset services provided to clients on a professional basis. Holding Bitcoin for yourself is not such a service. Recital 83 also states that hardware or software providers of non-custodial wallets should not fall within the Regulation's scope.

At the latest on July 1, 2026. Article 143(3) let firms operating under national law before December 30, 2024 continue until that date, or until authorization was granted or refused, whichever came first. Member States could refuse or shorten the transition.

ESMA points investors to its Interim MiCA Register. In its statement of December 4, 2025, ESMA warned that firms operating after the transitional period "are not guaranteed to be authorised under MiCA" and asked investors to check the register to confirm their provider is authorized.

MiCA requires it to be legally segregated. Under Article 75(7), crypto-assets held in custody must be segregated from the provider's estate "so that creditors of the crypto-asset service provider have no recourse" to them, "in particular in the event of insolvency."
