Crypto Market in the European Union: MiCA and Business Models

Bitcoin was the breakthrough innovation demonstrating peer-to-peer transfer of value without a central bank and has since expanded to countless innovations such as smart contract applications, decentralized finance protocols and asset tokenization. The EU is moving from scattered state-specific rules governing cryptocurrency activities to a coherent European regulatory regime. This paper review the transition to a harmonized framework in 2024-2025 from a doctrinal-institutional perspective, unpack how to carry out the three main legislative instruments: MiCA, TFR on information accompanying transfers of funds and transfers of certain crypto-assets and amending the EU directive and the EU AML package . Moreover, I look at the implications of DAC8 for the tax treatment of crypto-assets and tokenized assets. In 2025, the market begins institutionalizing, as MiCA requires significant compliance measures in terms of governance, transparency and conduct for CASPs to get licensed. Moreover, in conjunction with the new TFR rules, compliance for CASPs, at least in the business models discussed, effectively transforms into an operational infrastructure issue revolving around data quality, process efficiency and interoperability. By way of comparison, I analyze eight example business models in eight representative EU markets that appear to be impacted. These include: two major exchanges, two broker-dealers offering cryptocurrency on trading platform, a provider of non-custodial software wallets, two DeFi protocol participants and two NFT platform providers. These fall into three general categories depending on their legal status, direct regulatory burden and level of engagement with decentralized technologies. Finally, harmonized regulatory frameworks like the one outlined for the EU increase operational fixed costs and favor consolidation, reduce the benefits for regulatory arbitrage and thereby boost user protection, although part of innovation may pivot towards B2B solutions.
