MiCA Regulation — What It Means for Estonian Crypto Users

In June 2024, the European Union's MiCA (Markets in Crypto-Assets) regulation came into effect, establishing uniform rules for crypto-asset service providers across the EU for the first time. For cryptocurrency users in Estonia, this brings both new opportunities and new obligations. Let us examine what MiCA actually changes.

What is MiCA?

MiCA is a European Union regulation that creates a unified legal framework for crypto-assets. It covers crypto exchanges, wallet service providers, stablecoins, and other crypto-assets. The regulation aims to protect investors, ensure market integrity, and establish clear rules across Europe.

MiCA came into force in two phases: stablecoin rules from June 2024 and full implementation from December 2024. To provide crypto services in the EU, a company must obtain a CASP (Crypto-Asset Service Provider) licence.

What Changed for Estonian Users?

Estonia was previously known as the easiest EU country for obtaining a crypto licence. Before MiCA, over 1,000 crypto service providers were registered in Estonia. After the introduction of stricter requirements, this number dropped dramatically. Here is what MiCA changed:

• Higher licence requirements: A CASP licence requires a minimum of EUR 125,000 in equity capital, liability insurance, and a compliance team.
• Better investor protection: Platforms must ensure segregation of client assets, transparent pricing, and a complaints handling process.
• EU-wide passport: A CASP licence is valid throughout the EU. This means a platform with an Estonian licence can serve all EU countries.
• Mandatory white paper: Issuers of new tokens must prepare a standardised white paper, similar to a securities prospectus.

Stablecoin Rules

MiCA establishes separate rules for stablecoins, dividing them into two categories:

• ARTs (Asset-Referenced Tokens): Tokens linked to multiple asset classes (e.g., Diem/Libra-type). The issuer must be licensed in the EU and maintain sufficient reserves.
• EMTs (E-Money Tokens): Tokens linked to a single fiat currency (e.g., USDT, USDC). The issuer must be registered in the EU as an electronic money institution and hold 100% reserves in a regulated bank.

In practice, this means that some stablecoins (e.g., Tether's USDT) may not comply with EU regulations and their trading could be restricted. Users should prefer stablecoins that meet MiCA requirements.

DeFi and MiCA

One of the biggest question marks around MiCA is decentralised finance (DeFi). In its current version, MiCA completely excludes truly decentralised protocols from regulation. This means that Uniswap, Aave, and similar protocols do not need a CASP licence.

However, the European Commission is obligated to prepare a report on DeFi by the end of 2025 and, if necessary, present new legislative proposals. So DeFi regulation may come in the future, but for now these protocols operate outside the MiCA framework.

DAC8 -- Tax Reporting Directive

In parallel with MiCA, the EU's DAC8 directive comes into force, requiring crypto service providers to share client transaction data with tax authorities. This means:

• Crypto exchanges will automatically report transactions to the Tax and Customs Board.
• The tax authority will be able to cross-check declared income against actual transactions.
• The probability of detecting undeclared crypto income increases significantly.

For investors in Estonia, the message is clear: declare all crypto transactions correctly. DAC8 makes concealment practically impossible.

Pros and Cons of MiCA

Conclusion

MiCA is the European Union's most important step in crypto regulation. For users in Estonia, it means better protection but also greater transparency and tax reporting obligations. We recommend using only MiCA-licensed platforms and keeping your tax records in order.

The maturation of the crypto market is an inevitable process, and MiCA is a step in that direction. Investors who adapt to the new rules will be better positioned in the long run.
