Last edited: 10.1.2025

Understand the new MiCA rules and their impact on your privacy as a cryptocurrency holder.

In this blog article, we will explore the new MiCA rules and their implications for cryptocurrency holders and future purchases. These regulations impact your privacy in unexpected ways, but by understanding them, you can take proactive steps to enhance your privacy and security. 

 

1. What is MiCA?

MiCA stands for Markets in Crypto-Assets Regulation, a comprehensive regulatory framework introduced by the European Union (EU) to govern the cryptocurrency and digital asset market across its Member States, effective from 2025.

MiCA affects any company that offers cryptocurrency-related services, like exchanges, wallet providers, and issuers of digital assets.

While MiCA may seem like a regulation targeting businesses, the real impact is on customers. Companies are required to comply with stricter AML and KYC regulations, which directly affect customers as these rules must be enforced on anyone who wants to buy, hold, or sell cryptocurrency.
 

2. Main Components of the MiCA Regulation

1. Authorization and Registration

  • Companies providing crypto-asset services must obtain authorization from the relevant national regulator in the EU.
  • They must register as Crypto-Asset Service Providers (CASPs) in the EU Member State where they operate.
  • A registered office and place of effective management in the EU are mandatory.

2. Anti-Money Laundering (AML) and Know Your Customer (KYC)

  • Mandatory KYC for all customers, regardless of transaction size or volume.
  • Implement robust AML and Counter-Terrorist Financing (CTF) frameworks to prevent illicit activities.
  • Conduct ongoing customer due diligence and monitor transactions for suspicious activities.
  • Report suspicious activities to national Financial Intelligence Units (FIUs).

3. Capital Requirements

Maintain a minimum amount of capital based on the type of services provided:

  • €50,000 for advisory services.
  • €125,000 for exchange or trading services.
  • €150,000 for custodial wallet services and other high-risk activities.

4. Consumer Protection

  • Act honestly, fairly, and professionally in the best interests of clients.
  • Provide clear, accurate, and non-misleading information, including:
    • Fees and costs.
    • Risks associated with crypto-asset transactions.
  • Implement measures to safeguard clients’ funds and data.

5. Transparency Requirements

  • Marketing and promotional materials must:
    • Be truthful and not misleading.
    • Clearly disclose risks, costs, and terms.
  • Publicly disclose information about the company’s financial health, services, and fees.

6. Risk Management

  • Establish risk management frameworks to address operational, market, and cybersecurity risks.
  • Ensure adequate systems for safeguarding clients’ crypto-assets and private keys.

7. Stablecoin Issuers

For companies issuing stablecoins (asset-referenced tokens or e-money tokens)

  • Maintain a reserve of assets equal to or greater than the value of issued tokens.
  • Publish a white paper with detailed information about the stablecoin, its risks, and its underlying assets.
  • Ensure the redemption of stablecoins at par value upon request.

8. Market Abuse and Insider Trading

  • Prohibit insider trading, market manipulation, and other forms of market abuse.
  • Implement systems to monitor and prevent such activities.

9. Technology Standards

  • Ensure IT systems are secure and resilient against cyber threats.
  • Use high standards for securing private keys and other sensitive customer data.

10. Passporting Across the EU

  • Once authorized in one EU Member State, CASPs can operate across all EU Member States under the MiCA framework, using the EU’s “passporting” system.

11. Environmental Disclosures

  • CASPs and issuers must disclose the environmental and energy impact of their crypto-asset activities, where applicable.

12. Reporting Obligations

  • Submit regular reports to regulators, including financial audits and transaction data.
  • Provide transparency about the company's governance and compliance measures.

13. Prohibition on Marketing Without Compliance

Companies outside the EU can only provide services passively (reverse solicitation) and are prohibited from marketing or promoting their services to EU customers unless they comply with MiCA regulations.

14. Enforcement and Penalties

Non-compliance can result in:

  • Fines and sanctions.
  • Revocation of authorization.
  • Blacklisting from providing services in the EU.

 

3. MiCA's Impact on Buying and Withdrawing Crypto

1. KYC Process:

Before using the exchange, the crypto owner must complete a Know Your Customer (KYC) process. This involves providing personal information, such as a government-issued ID, proof of address, and possibly additional verification steps like a selfie or video call.

2. Transaction Monitoring:

The exchange will monitor all transactions for compliance with Anti-Money Laundering (AML) and Counter-Terrorist Financing (CTF) regulations. Large or unusual withdrawals could be flagged for further investigation or reporting.

3. Limits and Reporting:

The exchange may impose limits on the size or frequency of transactions, particularly for unverified users. Any transactions above certain thresholds may be reported to the national Financial Intelligence Unit (FIU).

4. Fees and Transparency:

The exchange must disclose all fees and costs associated with buying crypto and withdrawing it to a private wallet. The owner should be aware of potential withdrawal fees, network fees, and exchange spreads.

5. Withdrawal to Private Wallets:

When withdrawing crypto to a private wallet, the owner might need to provide the address of the receiving wallet and confirm ownership. Some exchanges could ask for additional verification for withdrawals to ensure compliance with AML rules.

6. Limited Anonymity:

MiCA rules require full transparency of transactions on regulated exchanges. Any attempt to use the exchange anonymously or through pseudonymous accounts will not be allowed.

7. Asset Availability:

The exchange must ensure that all listed crypto assets comply with MiCA standards. The crypto owner will only be able to buy assets that the exchange has legally registered or authorized under MiCA.

8. Consumer Protection:

If an issue arises (e.g., delays or errors in withdrawal), the exchange must provide clear channels for complaint resolution and be transparent about the cause. Refund policies and dispute resolution mechanisms must comply with MiCA requirements.

9. Environmental Disclosure:
For certain crypto assets, the exchange may provide information about their environmental and energy impact. This ensures transparency for eco-conscious buyers.

10. Cross-Border Operations:
If the crypto owner is using an exchange based in another EU country, MiCA’s passporting rules ensure consistent regulations. This means the same rules apply regardless of where the exchange is based within the EU.

 

4. MiCA's Real-World Implications for Buying and Selling Crypto

The new MiCA rules aim to make crypto buying and selling safer. Companies must meet stricter requirements to comply. However, the user experience will suffer significantly. Stricter KYC and AML rules will reduce user privacy, leading to potentially dangerous implications. Crypto transactions could feel like running an obstacle course.

Let’s break down the key aspects:

The Burden of Providing and Maintaining Private Data

Under MiCA, using exchanges will require you to provide extensive personal information, such as proof of residence, a passport, and possibly income statements. Additionally, you'll need to keep this data updated regularly, including any changes to your financial situation. This creates a significant ongoing administrative burden for anyone buying, holding, or selling cryptocurrency.

Increased Scrutiny, Account Freezes, and Risk of Losing Funds

Exchanges may freeze your account if their algorithms flag transactions or limits as unusual. They can then demand further evidence, such as proof of where the funds came from and where they are going. Similar to the banking system, crypto users may face invasive questions when withdrawing larger amounts or handling high transaction volumes.

Worse, under MiCA, exchanges will have the right to keep your funds if they determine that the evidence you provide is insufficient to justify the transactions. This scrutiny is often based on oversimplified logic, such as comparing your transaction volume to your monthly income and demanding proof, even when the two are unrelated. These measures, while aimed at preventing illicit activity, could create significant risks and hurdles for legitimate users.

Self-Custody Comes with Strings Attached

Self-custody is still permitted under MiCA, but only if you link your withdrawal address to your KYC information. This allows exchanges to track the flow of transactions from your wallet. They could infer, for example, that if you moved your funds, you may have sold them or used them in other transactions. Such monitoring adds a layer of scrutiny, even for users choosing to hold their funds privately.

Beware of Tainted Coins

Exchanges now use advanced tracking systems to assess the history of the coins you send them, assigning a rating based on the likelihood that those coins were involved in illicit activities. If you unknowingly own such coins—perhaps purchased on a peer-to-peer exchange—the exchange might confiscate them or, in extreme cases, shut down your account entirely.

If you're unsure whether your coins have a tainted history, avoid depositing them into a centralized exchange unless you're fully aware of the risks involved.

Centralized Systems Increase the Risk of Data Leaks

History shows that private information stored on centralized systems is often leaked, whether through hacks or insiders selling data for profit. Such information holds significant value on dark markets. Numerous past incidents have demonstrated how centralized storage of sensitive data can lead to serious privacy breaches, putting individuals at risk.

Data Leaks Increase the Risk of Physical Attacks

If hackers access personal data about Bitcoin holders, the risks can be severe. With information like names, addresses, and wallet balances, criminals can track individuals. This may lead to physical attacks, such as stealing wallets or forcing people to hand over their keys.

This threat is part of operational security (OpSec) in crypto and must be taken seriously. Past incidents show how leaked data has led to dangerous confrontations.

MiCA's Impact on Tax Evasion

MiCA significantly reduces the potential for tax evasion in the crypto space. With stricter KYC and AML requirements, every transaction is tied to an individual’s identity, making it easier for authorities to track funds. Exchanges must report detailed transaction data, ensuring transparency and leaving little room for undeclared assets.

 

5. Alternative Legal Ways to Obtain Bitcoin

If you prefer not to use a centralized exchange regulated by MiCA, there are still several other ways to legally buy Bitcoin. However, these options often come with trade-offs, especially regarding cost, convenience, and security.

Bitcoin Mining

In the early days, mining Bitcoin was possible using small USB-sized devices. Today, mining requires specialized hardware, which can be expensive to purchase and operate. Bitcoin miners consume a lot of electricity, which is converted almost entirely into heat. Running a mining operation also requires technical knowledge and a suitable space to manage noise, heat, and ventilation.

A niche solution gaining popularity involves using small mining systems for heating purposes, such as in private homes or greenhouses. This approach allows electricity to serve two purposes: heating and mining Bitcoin. However, efficiency depends on factors like local electricity prices and the hardware's quality.

Solo Lottery Mining

Most Bitcoin mining is done through pools, where participants share rewards to increase the chances of earning Bitcoin. However, solo mining is an option for those willing to accept the very low probability of earning the full block reward. Running a small, energy-efficient miner is possible, but it functions more like a "lottery ticket" due to the slim odds of success.

Earning a Salary in Bitcoin

More companies now offer the option to pay employees partially or fully in Bitcoin. This is a straightforward and legal way to obtain Bitcoin without using an exchange, and it integrates directly into your income stream.

Private Buying and Selling of Bitcoin

Buying or selling Bitcoin privately is legal but only recommended if you trust the transaction partner. Private transactions carry a high risk of scams, especially for beginners. Avoid using apps that facilitate meetups for private trades, as these often involve significant risks of fraud or theft.

Peer-to-Peer (P2P) Exchanges

P2P exchanges that don’t require KYC offer greater privacy but come with several disadvantages.

  • These platforms are riskier for beginners, as dishonest traders may exploit inexperienced users.
  • It’s advisable to start with small amounts to minimize losses and learn how the process works.
  • P2P platforms often charge premiums of 10–20% above market price, making Bitcoin more expensive.
  • There’s also a risk of receiving "tainted coins," which could be flagged as suspicious on centralized exchanges, potentially leading to account issues or confiscation.

Bitcoin Gift Vouchers

Some vendors sell gift vouchers that can be redeemed for Bitcoin. While this method offers privacy, it is often limited to small amounts (e.g., under €50). These services can be difficult to find, and the terms are often unclear.

Exchanges Outside the EU

MiCA applies to companies located within the EU, but it does not regulate exchanges based outside the EU. These platforms may offer services with fewer requirements. Although the EU cannot prevent its residents from using services provided by companies outside its jurisdiction, it has prohibited any form of promotion or advertising by these companies. This restriction makes it difficult for such businesses to attract customers and maintain long-term operations.

 

6. Summary

The Markets in Crypto-Assets Regulation (MiCA) introduces strict rules for crypto services within the EU, focusing on transparency, consumer protection, and the prevention of illicit activities. While these regulations aim to create a safer environment, they bring significant changes for users. Stricter KYC and AML requirements mean reduced privacy, more administrative burdens, and the risk of account freezes if transaction details don’t meet new standards.

For those who prefer more private options, alternatives such as peer-to-peer exchanges, private trades, or even Bitcoin mining still exist. However, these come with challenges, including higher premiums, potential risks of scams, and receiving tainted coins that could be flagged on centralized exchanges.

MiCA also limits EU residents’ access to non-compliant exchanges outside the EU by banning promotion or advertising. While these services remain legal under reverse solicitation, finding and using them responsibly requires careful consideration.
