A stark regulatory paradox is unfolding inside the European Union's landmark crypto framework: rather than channeling digital-asset activity into supervised, transparent platforms, the Markets in Crypto-Assets regulation — universally known as MiCA — appears to be driving a significant share of retail users in the opposite direction, toward unhosted wallets that no regulator can monitor. That, at least, is the warning being sounded by one of the industry's most prominent executives, and the data point he cites is arresting: seven out of every ten EU-based users who departed Binance following MiCA enforcement did not migrate to a competing licensed exchange. They moved to self-custody.
Binance co-Chief Executive Officer Richard Teng made the disclosure publicly, framing it as evidence that MiCA is producing outcomes directly contrary to its stated objectives. The regulation, which entered full force as the most comprehensive crypto-asset rulebook ever enacted by a major jurisdiction, was designed to bring order, investor protection, and financial-crime safeguards to a market that had long operated in regulatory grey zones. The premise was straightforward: mandate that exchanges and issuers meet rigorous disclosure, capital, and compliance requirements, and users would benefit from a safer, better-governed ecosystem. Teng's 70% figure calls that premise into serious question.
The Self-Custody Migration Problem
Self-custody wallets — software or hardware tools that allow individuals to hold their own cryptographic private keys, entirely outside the custody of any intermediary — have always occupied an ideologically significant corner of the crypto market. For purists, they represent the founding promise of decentralized finance: financial sovereignty without institutional dependence. For regulators, they represent a surveillance blind spot. Transactions initiated from a self-custody address cannot be automatically attributed to a known individual, travel-rule obligations cannot be enforced end-to-end, and Anti-Money Laundering checks that exchanges are legally required to perform simply do not apply.
When MiCA compliance obligations became operational and exchanges moved to restrict or delist services for EU users who could not satisfy heightened Know Your Customer and other requirements, the intended consequence was a cleaner, more accountable market. The unintended consequence, if Teng's figures are accurate, was a mass migration of ordinary retail participants away from the very infrastructure regulators can observe and influence. The 70% share is not a marginal rounding error — it represents a decisive majority of the churned EU user base choosing opacity over compliance, not because they are bad actors, but because the frictionless alternative was a self-custody wallet rather than another licensed platform.
A Regulatory Paradox with Systemic Implications
The irony is not lost on market observers. MiCA was in many respects a triumph of legislative ambition — a unified, pan-European rulebook replacing a patchwork of inconsistent national approaches and positioning the EU as a standard-setter for the rest of the world. The European Banking Authority and the European Securities and Markets Authority invested years in its design, and it was widely lauded by institutional players who welcomed the legal certainty it provided for stablecoin issuers and crypto-asset service providers. For large, well-capitalised exchanges prepared to absorb compliance costs, MiCA was manageable, even welcome competitive differentiation.
For EU retail crypto participants, however, the compliance burden imposed on their chosen platforms translated into a degraded user experience — restricted product offerings, additional verification hurdles, and in some cases, service terminations. Rather than accept a diminished experience on a regulated platform, the data Teng presented suggests the majority simply bypassed the regulated ecosystem altogether. This is not a theoretical regulatory arbitrage scenario; it is reportedly happening at scale, with seven in ten departing users making the same choice.
The dynamic echoes a broader tension that financial regulators across jurisdictions have wrestled with: when compliance costs and restrictions become sufficiently burdensome, they do not eliminate demand — they redirect it. In traditional finance, that redirection historically led to offshore accounts or shadow banking. In crypto, the equivalent is a hardware wallet purchased for a nominal sum, after which the user is, as Teng put it, entirely beyond regulators' reach.
What This Means for EU Crypto Policy
The Binance co-CEO's public intervention carries weight precisely because it comes from a platform that has invested heavily in regulatory engagement and that has strong commercial incentives to keep users on its licensed infrastructure rather than lose them to self-custody entirely. Teng is not making an anti-regulation argument in the abstract — he is presenting an operational outcome from Binance's own EU user base that policymakers cannot easily dismiss as industry lobbying.
For EU regulators and the European Commission, the challenge now is whether to treat the self-custody migration as evidence that MiCA's implementation needs recalibration, or whether to pursue tighter restrictions on unhosted wallets themselves — a path that carries its own profound civil liberties and technical enforcement complications. The European Central Bank and ESMA have both signaled interest in the unhosted wallet question in prior policy consultations, but legislating effective controls over self-sovereign cryptographic keys remains technically and politically fraught territory.
What the 70% figure ultimately illustrates is that regulatory design in crypto cannot treat user behaviour as static. When the regulated option becomes significantly less attractive, a digitally literate user base has an immediate, low-friction alternative that predates MiCA, will survive it, and grows more capable with each hardware wallet generation. Policymakers who ignore that elasticity do not eliminate the risk they sought to contain — they simply lose visibility into it.
