The shift from 'regulation by enforcement'
For much of crypto's earlier history, especially in the United States, the primary way regulators engaged with the industry was through enforcement actions after the fact, suing or fining companies for violations rather than publishing clear rules in advance for how to comply. This left builders and investors in a genuinely difficult position: it was often unclear which activities were permitted until a regulator decided one wasn't, which discouraged exactly the kind of serious, well-capitalized institutions this course has already described as newly active in the space.
That environment has been shifting toward comprehensive, purpose-built frameworks instead. The European Union's Markets in Crypto-Assets regulation, known as MiCA, is the clearest example, a single, detailed rulebook covering how crypto-asset issuers and service providers must operate across the entire EU, replacing a patchwork of inconsistent national rules with one standard. In the United States, stablecoin-specific legislation and broader market-structure proposals have moved further than in prior years toward giving issuers and exchanges clearer, codified rules rather than case-by-case enforcement outcomes.
