And yet, despite that scale, stablecoins remain largely confined to the crypto ecosystem. The broader public has barely noticed.

Why Stablecoins Matter Beyond Crypto

The basic case for stablecoins is straightforward. They settle fast, operate around the clock, and can move across borders with less friction than traditional banking. They support programmable payments which is money that can execute conditions automatically, without intermediaries. In some cases they offer yields that compare favourably with conventional deposit accounts.

But one underappreciated advantage is privacy. Stablecoins provide users with a certain degree of privacy, more than a traditional bank deposit but less than a privacy coin like Monero, which is a sweet spot for payment medium to be widely adopted. That means that stablecoins can give users greater control over their payment data than a traditional bank account affords. It matters because payments generate enormous amounts of valuable data, and today that data flows almost entirely to incumbent institutions. Stablecoins shift some of that bargaining power back toward users, not by replacing banks, which still provide the reserve custody, payment rails, and customer acquisition that stablecoin issuers depend on, but by introducing a layer of competition that could make the overall system healthier.

There are also humanitarian dimensions worth taking seriously. NGOs supporting refugees, politically marginalised communities, or people without access to formal banking infrastructure have real use for faster, lower-cost global transfers. These are not hypothetical edge cases. They are some of the most compelling arguments for why stablecoins could matter to people who have never held a cryptocurrency in their life.

So Why Haven't They Gone Mainstream?

Regulation has been the most visible barrier. For years, the absence of clear legal frameworks left users with no reliable way to assess whether an issuer was properly supervised, whether reserves were real, or whether redemption rights would be honoured in a crisis. That uncertainty suppressed adoption among anyone who wasn't already comfortable operating in grey areas.

The picture is improving. The EU's MiCA framework is a meaningful step toward the kind of legal clarity that mainstream users require. Euro stablecoin market capitalisation reportedly doubled during 2025 following MiCA implementation and now stands at roughly $890 million (Coindesk, CoinGecko). It is still small, but directionally significant.

The graph above shows the number of newly created wallets transacting in Euro-backed stablecoins (EURC, EURS, EURe) on Ethereum every week from the start of 2024 through April. Even though the numbers dropped significantly in April, the baseline is still higher than at any point in early 2024, before MiCA was properly rolled out.

Consumer protection remains a gap. Stablecoin holders do not currently receive protections equivalent to bank deposit insurance, and for most people that is a serious obstacle. Why move money into a product you barely understand if it offers fewer safeguards than a standard current account? That said, regulation alone has never guaranteed mass adoption. Revolut and PayPal both achieved it not primarily through regulatory comfort, but through genuinely simple and fast user experiences. Stablecoins have not yet managed that.

User experience is still the quiet killer. For anyone outside the crypto world, accessing stablecoins remains unnecessarily hard. Wallet setup is confusing, and the terminology is alienating. Security practices like seed phrases, private keys, and on-chain transactions are second nature to experienced users, but baffling and intimidating to newcomers. True, UX has improved a lot over the last few years, but more work is needed to build a truly convenient and friendly interface.

On-ramps and off-ramps are still broken in too many places. Stablecoins depend on banking connections to be useful, and those connections are unreliable. Users face slow transfers, high fees, payments blocked by exchanges, compliance delays, and inconsistent access depending on where they live. These frictions are not minor inconveniences. They directly undercut the core promise of faster, cheaper, more accessible money movement.

Trust, finally, is everything. Outside crypto circles, digital assets are still widely perceived as speculative and volatile. That reputation is not entirely unfair, given the history, and it makes trust a critical asset for any issuer hoping to reach mainstream users. Circle's USDC and EURC have benefited from a stronger perception of compliance and transparency than many of its competitors. The chart below highlights a significant surge in EURC transfer volume on Ethereum in 2025 and 2026, driven by Circle's strategic push into the EU market under MiCA regulations. This proactive compliance allows Circle to secure a critical first-mover advantage, cementing its reputation as the most established and financially robust issuer in the stablecoin sector.

But trust is also fragile. When Silicon Valley Bank failed in 2023, concerns about USDC's reserve exposure briefly broke its dollar peg before confidence was restored. It recovered but the episode illustrated how quickly sentiment can turn, and how much work issuers still have to do to be genuinely trusted by people who are not already believers.

Where Does This Leave Us?

Stablecoins already represent a market worth hundreds of billions of dollars. The long-term potential is real and, I would argue, underestimated by most people outside the industry. The use cases from cross-border remittances to humanitarian payments to programmable finance are not theoretical.

But mass adoption will not arrive automatically. It will require clear and consistent regulation, user experiences that do not assume technical sophistication, reliable banking connectivity, and the slow, unglamorous work of building public trust. The technology is largely ready. The surrounding infrastructure is not.

The real question is not whether stablecoins can go mainstream. Not really. It is whether the industry has the patience and discipline to build the foundations that would actually get them there.
