The Markets in Crypto-Assets Regulation — known as MiCA (Regulation EU 2023/1114) — is the European Union's comprehensive legal framework for crypto assets. Agreed by the European Parliament in April 2023 and entering into force in June 2023, MiCA became fully applicable in December 2024. It is the first major jurisdiction-wide crypto regulation of its kind, covering issuers of crypto assets and crypto asset service providers (CASPs) operating across all 27 EU member states.
This guide explains what MiCA covers, which digital assets fall under its scope, what it means for exchanges and retail traders, how it affects portfolio tracking and reporting, and what to expect from ESMA's ongoing technical standards in 2025 and beyond.
1. What Is MiCA and Why Was It Created?
MiCA — Markets in Crypto-Assets Regulation (EU) 2023/1114 — was created to replace the patchwork of national crypto frameworks across EU member states with a single, harmonised rulebook. Before MiCA, a crypto exchange licensed in one EU country could not automatically passport its services into another without navigating 27 different regulatory environments. This fragmentation created legal uncertainty for businesses and left retail investors with inconsistent protections depending on where they lived.
The regulation was proposed by the European Commission in September 2020, negotiated through trilogues between Parliament, Council, and Commission, and formally adopted in May 2023. It entered into force on 29 June 2023. Stablecoin rules (for Asset-Referenced Tokens and E-Money Tokens) became applicable from 30 June 2024, while the broader CASP licensing regime became mandatory across the EU from 30 December 2024.
MiCA pursues three core objectives: consumer and investor protection, market integrity, and financial stability. It does so by requiring issuers of crypto assets to publish whitepapers, imposing conduct-of-business rules on CASPs, establishing market abuse prohibitions analogous to those in traditional securities law, and creating a passporting system so authorised CASPs can operate across the EU single market. The regulation was also designed to provide legal certainty that encourages innovation, rather than simply restricting it.
2. Which Crypto Assets Are Covered by MiCA?
MiCA establishes three categories of crypto assets subject to its rules. First, Asset-Referenced Tokens (ARTs) are tokens that reference the value of multiple official currencies, commodities, or other crypto assets. Second, E-Money Tokens (EMTs) are tokens that reference a single official currency and function as electronic money. Third, a catch-all category covers all other crypto assets not classified as ARTs or EMTs — this includes most utility tokens, access tokens, and the majority of cryptocurrencies such as Bitcoin and Ether (in their current form).
Notably, several asset types are explicitly excluded from MiCA's scope. Non-Fungible Tokens (NFTs) that are truly unique and non-fungible fall outside MiCA, though fractionalised NFTs or collections that behave like fungible tokens may be captured. Decentralised Finance (DeFi) protocols where no identifiable issuer exists are also outside MiCA's direct scope — though the European Commission is required to review this by December 2025 and may propose additional legislation. Central Bank Digital Currencies (CBDCs) issued by the ECB or national central banks are excluded, as are deposits and structured deposits. Security tokens that qualify as financial instruments under MiFID II remain governed by existing securities law rather than MiCA.
Bitcoin and Ether are regulated under MiCA's general crypto-asset category when offered to the public, but mining and proof-of-work consensus mechanisms are not directly regulated. The ESMA and EBA have published detailed Q&A documents to help market participants classify their specific tokens correctly.
3. What Does MiCA Mean for Crypto Exchanges and Traders?
For crypto exchanges and custodial wallet providers operating in the EU, MiCA introduces mandatory authorisation as a Crypto Asset Service Provider (CASP). Firms that were previously registered under national anti-money-laundering frameworks must now obtain a full MiCA CASP licence — a more demanding process that requires demonstrating organisational fitness, governance standards, capital requirements (minimum €125,000 for exchange operators), cybersecurity measures, and complaints handling procedures. Once licensed in one EU member state, a CASP can passport its services across the entire EU, substantially reducing cross-border complexity.
For retail traders and investors, MiCA introduces a range of protections that did not previously exist uniformly across Europe. Exchanges must provide clients with a personalised cost and charges disclosure before executing orders. Whitepapers for newly issued crypto assets must contain standardised disclosures — risks, issuer information, token characteristics — so retail investors have a consistent basis for comparing projects. Market manipulation, insider trading, and wash trading in crypto assets are now explicitly prohibited under MiCA's market abuse regime (Title VI), with enforcement powers granted to national competent authorities (NCAs).
CASPs must also segregate client assets from their own proprietary holdings, maintain adequate liquidity, and publish best-execution policies. These requirements are deliberately modelled on MiFID II obligations for investment firms, creating a parallel regulatory architecture for the crypto sector. Traders who previously operated through exchanges in less regulated jurisdictions — Seychelles, Cayman Islands, etc. — may find that some of those platforms choose not to seek EU authorisation and stop serving European customers, narrowing the available venues but increasing the reliability of those that remain.
4. How Does MiCA Impact Portfolio Tracking and Reporting?
MiCA's emphasis on transparency and investor protection has direct implications for how crypto traders maintain records and report their holdings. CASPs are now required to keep detailed transaction records and provide periodic account statements to clients — meaning regulated exchanges must report to you, not just to regulators. This generates more structured data that investors can use for tax reporting and portfolio analysis.
From a tax reporting perspective, MiCA does not create harmonised EU-wide crypto tax rules — taxation remains a member-state competence. However, the DAC8 directive (adopted alongside MiCA) requires CASPs to report client transaction data to national tax authorities automatically from 2026. This makes accurate self-reporting increasingly important, because the data authorities will receive will be granular and hard to reconcile against inconsistent personal records.
For investors managing diversified portfolios that include both crypto assets and traditional investments such as ETFs, stocks, and bonds, the practical challenge is consolidating performance data across asset classes. DonkyCapital is designed exactly for this purpose: you can import your crypto transactions alongside your traditional broker data, track your overall portfolio performance using time-weighted return (TWRR), monitor your cost basis per asset, and generate a unified view of your net exposure. As CASP-generated statements become more standardised under MiCA, the data inputs for such tools will become more reliable and easier to reconcile.
5. What Are the Next Steps Under MiCA After 2024?
MiCA's entry into full force in December 2024 was the beginning, not the end, of the EU crypto regulatory process. ESMA and EBA have been publishing a series of Level 2 technical standards — regulatory technical standards (RTS) and implementing technical standards (ITS) — that fill in the operational details of MiCA's framework. These cover areas including the content and format of crypto asset whitepapers, the specific disclosures required in client cost and charges statements, liquidity stress-testing requirements for stablecoin issuers, and cybersecurity incident reporting procedures.
A mandatory review of MiCA is required by December 2025, at which point the European Commission must report to Parliament and Council on the regulation's effects and may propose amendments or entirely new legislation covering DeFi, NFTs, and crypto lending. The outcome of this review will determine how much of the crypto ecosystem remains outside EU direct regulation in the medium term.
For stablecoin issuers specifically, the rules are already highly restrictive: ARTs and EMTs with significant transaction volumes face hard caps on daily transactions (a maximum of 1 million transactions or €200 million in value per day) if the EBA determines they pose a threat to EU monetary sovereignty. Major stablecoin issuers such as Tether and Circle have been navigating EU licensing requirements, with some obtaining EMT licences in EU jurisdictions such as France and Luxembourg.
For individual investors, the practical implication is that the regulatory environment for crypto in Europe will continue to evolve and tighten. Staying compliant means keeping detailed records of all transactions, using regulated CASPs where possible, and ensuring your portfolio tracking tool can handle the growing volume of structured data that regulated exchanges will generate under MiCA.
Frequently Asked Questions about MiCA
Does MiCA apply to retail crypto investors or only to businesses?
MiCA primarily regulates businesses — issuers of crypto assets and CASPs such as exchanges and custodial wallets. However, retail investors benefit indirectly through the investor protection rules, whitepaper requirements, and market abuse prohibitions. Individual peer-to-peer transactions between private individuals are generally outside MiCA's scope.
Is Bitcoin regulated under MiCA?
Bitcoin falls under MiCA's general crypto-asset category when it is offered to the public or traded on a regulated EU platform. However, Bitcoin mining and the underlying proof-of-work protocol are not directly regulated. Exchanges offering Bitcoin trading to EU customers must hold a CASP licence.
What happens to crypto exchanges that do not obtain a MiCA CASP licence?
Exchanges that cannot or choose not to obtain a CASP licence by December 2024 may no longer legally offer services to EU-based customers. In practice, many non-EU exchanges have already implemented geo-blocking for EU users or have applied for licences in EU member states. Some smaller or higher-risk platforms may simply exit the EU market.
Does MiCA create a single EU crypto tax?
No. MiCA does not harmonise crypto taxation across EU member states. Tax treatment of crypto assets — capital gains, income classification, reporting obligations — remains a matter for each member state individually. However, the DAC8 directive will require CASPs to report EU client transaction data to national tax authorities from 2026, increasing tax reporting accuracy.
Are DeFi protocols regulated under MiCA?
Most DeFi protocols are currently outside MiCA's direct scope because there is no identifiable issuer or CASP. However, the European Commission is required to review the DeFi question by December 2025 and may propose new legislation. Fully decentralised protocols are the most likely to remain unregulated, while protocols with a central team or governance token that controls protocol upgrades may face scrutiny.
How does MiCA affect stablecoins like USDT or USDC?
Stablecoins that reference a single fiat currency (e.g. EUR or USD) are classified as E-Money Tokens under MiCA and must be issued by an EU-authorised electronic money institution. Stablecoins referencing multiple assets are Asset-Referenced Tokens with additional capital and reserve requirements. Tether (USDT) is not currently MiCA-compliant and cannot be issued from within the EU, though trading on EU-licensed exchanges may still be permitted under certain conditions.
How can DonkyCapital help me track my crypto portfolio under MiCA?
DonkyCapital lets you import your crypto transactions from exchanges alongside your traditional investments, calculate your cost basis, track time-weighted return across all asset classes, and maintain clean records for tax reporting. As CASP-generated statements become more standardised under MiCA, the data flows into portfolio tracking tools will become more reliable.
