MiCA is a set of regulations in the European Union that governs the issuance and provision of services pertaining to cryptocurrencies, stablecoins, and related assets. It is a landmark regulation in that it is the first such legislation worldwide and when it takes effect in the coming years, it could have a significant impact on the crypto space in Europe. MiCA does not cover most NFTs (except fractionalized NFTs and NFTs released as collections), nor does it cover DeFi apps that exist without an intermediary. It requires crypto-asset service providers to adhere to common standards regarding security, anti-money laundering protections, and a host of other protocols. It also sets clear rules for token issuers and crypto asset service providers, and establishes a new framework for crypto asset regulation where it is not already covered by existing financial legislation. Algorithmic stablecoins are banned entirely under MiCA, and other stablecoins face stricter requirements, including the need to have reserves to match liabilities. MiCA means little will change for the crypto investor in terms of procedure, however, it aims to make consumers in the crypto space better protected in a variety of ways.
This is good news for the cryptocurrency industry as it means more secure and transparent practices for investors, and more control and regulation for service providers.
