Spanish-language outlet CriptoNoticias reported on May 28 that the monthly transaction volume of crypto payment cards reached $660M, and noted that the payment ecosystem is moving toward a model where “liquidity is no longer concentrated on a single network.” One thing needs to be clarified up front: the $660M figure comes from CriptoNoticias’ report, and the original article does not clearly specify which on-chain data provider or issuer report the figure was compiled from. For that reason, this article treats it as a directional signal rather than a reconcilable, precise number — and we recommend readers do the same when citing it.
Editorial take: what U card users should really pay attention to isn’t “$660M” — it’s “multi-chain”
Setting aside the hard-to-verify total, the part of this story with the most information value for USDT virtual card users is the phrase “liquidity is no longer concentrated on a single network.”
It corresponds to a concrete decision you face every day: which chain to use when topping up. For the same card, moving USDT from an exchange to your card account via TRC-20, ERC-20, or an L2 can result in fees and settlement times that differ by several multiples. As industry liquidity spreads across multiple networks, which top-up chains an issuer supports — and which chain it recommends by default — directly determines your actual cost.
Applied to specific cards:
- MPCard (the Asia Elite variant), which runs on an Asia-Pacific route, and the exchange-affiliated Bybit Card, both involve the step of “which chain you top up the card from” — the more chains supported, and the more cost-efficient the default chain, the lower your long-term holding cost.
- For users tied to a single exchange ecosystem, multi-chain fragmentation means you’re not locked into one network.
Timeline expectations:
- Within 7 days: No card will adjust its fees or limits because of this news. This is a market-observation report, not a policy change.
- Within 30 days: Worth watching whether issuers update their “supported top-up networks” lists. Under the multi-chain trend, adding new chain support is a common move.
- Within 90 days: If the total volume growth holds up, more issuers may optimize fee guidance around default top-up chains. Adding “which top-up chains are supported” to your card-comparison checklist is something you can do right now.

Historical context: the transaction-volume narrative isn’t new
Placed in historical context, this story shares similarities with — and differences from — past “crypto payment milestone” reports.
What’s similar: this kind of “monthly volume surpasses $X hundred million” narrative resurfaces periodically. It’s typically driven by aggregated data or a single issuer’s quarterly report, and spreads through secondary media coverage. Readers can easily mistake an unlabeled methodology total for an established industry fact.
What’s different: this report’s core narrative isn’t “record total volume” but “liquidity spreading across multiple networks.” That’s a structural observation, and it holds up better over time than a raw number alone — because it maps to a choice users actually face every time they top up, rather than just serving as a PR milestone.
For comparison, Visa’s crypto solutions page has long disclosed its own crypto-related settlement capabilities — this kind of official page is a better starting point for verification than an aggregated figure relayed through media. We recommend that whenever readers encounter any “industry monthly volume” number, they first ask: who defined the methodology, and does it measure settlement volume or spending volume?
Regulatory and compliance boundaries: this news doesn’t change any legal status
To be clear: this is a market report, it does not involve any new regulatory action, and it does not change the existing legal status of USDT cards in any jurisdiction.
- In the EU, stablecoin- and card-issuance-related business is governed by the MiCA framework, and issuers must operate under license. Users planning to use a U card in the EU can refer to the EU Compliance Guide to understand licensed issuers and KYC requirements.
- For stablecoin/payment licensing paths in Hong Kong and Singapore, see the Hong Kong Compliance Guide and Singapore Compliance Guide respectively.
“Multi-chain liquidity” itself is not a regulatory event, but it can indirectly affect compliance: which chains an issuer supports is often tied to its anti-money-laundering controls and on-chain traceability capabilities. This falls within the issuer’s internal risk-management scope. Currently, no jurisdiction imposes additional restrictions on issuers for “supporting multi-chain top-ups” — it is neither prohibited nor explicitly exempted, and sits within the realm of ordinary business discretion.
Key checkpoints worth watching next
- Secondary disclosure of the data methodology: watch for whether an original data provider (such as Visa or an on-chain analytics firm) confirms the methodology behind this $660M figure. Until then, this number can only be treated as “reported.”
- Issuer top-up chain list updates: over the next 30 days, watch whether Bybit Card, MPCard, and others add or adjust supported top-up networks.
- EU MiCA implementation details: licensing and disclosure requirements related to stablecoin issuance are still being finalized; EU users should keep tracking developments.
- The next volume report: watch for whether a subsequent, reconcilable industry report with clearly labeled methodology emerges to validate this trend.
Editorial recommendations
- Users holding MPCard or Bybit Card: no action needed. This news does not affect your card’s fees, limits, or availability.
- Users currently choosing a card: add “which top-up chains are supported, and how competitive is the default chain’s fee” to your comparison checklist. Under the multi-chain trend, the impact of chain choice on long-term cost may exceed the difference in a card’s monthly fee. For each issuer’s specific supported chains, refer to their official top-up documentation.
- What not to do: don’t judge a card as more worth applying for based on an unverified “$660M” figure. Total transaction volume has no direct bearing on your personal settlement speed or fees — those depend on the chain you choose and the issuer’s fee structure.
Readers unfamiliar with the basic concept of U cards can first read What Is a U Card, then return to judge what this kind of industry figure actually means for them.
