The data point is brutal: EURe’s share of crypto card payments has collapsed to 2%. USDC holds the rest. This is not a blip. It’s a structural verdict on the euro stablecoin experiment. I’ve been tracking this space since the 2021 NFT bubble, and the pattern is stark—narratives about compliance don’t move the needle if liquidity is absent. Let me unpack why this matters, and why the market is misreading the signal.
Context: The Stablecoin Payment Landscape
Crypto card payments are the bridge between digital assets and everyday spending. Visa and Mastercard have partnered with issuers like Wirex, Crypto.com, and Binance to offer cards that convert stablecoins to fiat at point of sale. The settlement currency matters. USDC, issued by Circle, dominates because it sits on deep liquidity pools, has multi-chain deployment, and is integrated into almost every major exchange and wallet. EURe, issued by the European fintech Monerium, is a euro-denominated stablecoin compliant with MiCA and the EU’s electronic money framework. On paper, it should be a natural fit for European users. But the data tells a different story.
Note: Sentiment turning bearish on L2s. But this is about stablecoins—the same principle applies: narrative without liquidity is dead weight.
The 2% figure comes from a recent industry report on crypto card transaction volumes. It’s not a single exchange snapshot; it’s aggregate across multiple card issuers. The report also notes that USDC commands over 90% of the segment, with USDT and other dollar-pegged coins splitting the remainder. EURe is a rounding error.
Core: Why USDC Wins—It’s Not About Technology
Let me be direct: the technology behind EURe and USDC is nearly identical. Both are fiat-collateralized, ERC-20 tokens with centralized redemption. Both have KYC/AML compliance. The difference is not ‘tech advancement’ but ‘network effects.’ USDC benefits from the dollar’s global reserve status, Circle’s banking relationships, and a first-mover advantage in the card space. When a card issuer chooses a settlement currency, they pick the one with the deepest liquidity and widest acceptance. That’s USDC.
Based on my audit experience from the 2020 DeFi derivatives crisis, I learned that liquidity depth trumps all else. Protocols that had deep order books survived the crash; those that relied on narrative were washed out. The same applies here. EURe has compliance, but it lacks the liquidity moat. The euro stablecoin market is fragmented—there are at least five other euro stablecoins (EURT, EURS, Stasis Euro, etc.)—and none of them have achieved critical mass. The card issuers don’t want to support multiple euro tokens when one dollar token covers 99% of user demand.
Note: Sentiment turning bearish on L2s. The parallel is clear: Ethereum L2s are fighting over fragmented liquidity, and the market is consolidating around the leaders. Stablecoins are doing the same.
Let’s drill into the numbers. The report doesn’t disclose total crypto card volumes, but we can infer from public data. In 2024, Visa processed over $1 billion in crypto-linked card transactions. If EURe’s share is 2%, that’s roughly $20 million annualized. For a stablecoin with a market cap of maybe $50 million (if we estimate based on public data), that’s a low velocity. In contrast, USDC’s market cap of $30 billion means its velocity in card payments is a fraction of a percent, but the sheer scale makes it dominant.
The incentive structure also favors USDC. Circle offers yield programs, corporate treasury integrations, and swap APIs. Card issuers can earn spread on the conversion. EURe’s issuer, Monerium, is a smaller firm with fewer resources. They can’t subsidize adoption the way Circle does. The result is a self-reinforcing cycle: more users → more liquidity → more integration → more users. EURe is stuck outside that loop.
Contrarian: The Blind Spot—USDC Overconcentration Is a Risk
Here’s the counter-intuitive angle: USDC’s dominance in crypto cards is a systemic risk. The entire segment is dependent on Circle’s solvency, regulatory compliance, and banking partnerships. If the US government tightens stablecoin rules (like the proposed GENIUS Act), Circle could be forced to hold only US Treasuries, which is fine, but if a banking crisis hits (like the Silicon Valley Bank collapse in 2023 where USDC briefly depegged), the entire crypto card industry could freeze. EURe, being a euro stablecoin, is insulated from US-specific banking shocks. That’s a structural hedge.
But the market isn’t pricing that. The narrative is that USDC is ‘too big to fail.’ I disagree. The Terra/Luna collapse taught me that no stablecoin is invulnerable. The difference is that USDC has real backing, but its concentration creates a single point of failure. If a major US bank drops Circle, the entire payment rail shuts down. EURe, with its European banking partners, offers geographic diversification. The market is ignoring this because it’s focused on current liquidity, not tail risk.
Note: Sentiment turning bearish on L2s. The same blind spot exists in L2s: everyone is betting on Arbitrum and Optimism, ignoring the risk of sequencer centralization. The market always overweights the current leader.
Another blind spot: MiCA. The EU’s MiCA framework is often cited as a catalyst for euro stablecoins. But the data shows that MiCA hasn’t moved the needle. Why? Because compliance is a floor, not a ceiling. Users don’t care about regulatory stickers if the token can’t be spent easily. EURe’s compliance is a necessary condition, but not sufficient. The market needs proof of utility, not just legal approval.
Takeaway: The Next Narrative Shift
So what’s the forward-looking play? The next narrative for euro stablecoins isn’t ‘crypto cards’—that ship has sailed. The real opportunity is in B2B payments, cross-border euro settlements, and corporate treasury use. If EURe can integrate with European banking rails (like SEPA Instant), it could carve out a niche in institutional payments. But that’s a different use case with different metrics. Retail card payments are lost to the dollar.
For investors, the takeaway is clear: don’t bet on euro stablecoins in the consumer card space. The liquidity and network effects are too entrenched. If you want exposure to stablecoin payments, go with the dollar-denominated leaders. But keep an eye on the regulatory tail risk. The next crisis could flip the narrative overnight.
Note: Sentiment turning bearish on L2s. The same logic applies: the market is overcrowded, and the only winners are those with genuine liquidity and user adoption. Everything else is noise.
I’ll be watching the next quarterly report to see if EURe drops below 2%. If it does, that’s the final confirmation that euro stablecoins are a dead end for retail payments. Until then, the data speaks for itself.
