Crypto cards have successfully solved spending, but privacy is emerging as the next competitive battleground.
For the last two years, the market competed on cashback, yield, UX, and self-custody, but the @ether_fi incident exposed a new challenge: protecting user financial data.
Here's what's actually happening:
—
● Crypto Cards Have Officially Reached Product-Market Fit
Crypto cards have evolved from a niche experiment into a legitimate payment category, with monthly spending volume growing from roughly $100M in early 2023 to more than $1.5B by late 2025.
• Cashback rewards
• Yield-bearing balances
• Higher spending limits
• Geographic expansion
• Better user experience
Over the last two years, competition has centered around making stablecoin payments feel as seamless as traditional fintech and neobank experiences.
Today, the category generates more than $18B in annualized spending volume, showing that the industry has largely solved the "Can people spend crypto?" problem.

● The Conversation Around Crypto Cards Is Changing
As the sector matures, users are no longer asking whether they can spend crypto, but what they sacrifice every time they do.
• Phase 1 (2024–2025): "Can I spend crypto anywhere?"
• Phase 2 (2025–2026): "How much cashback do I get?"
• Phase 3 (Emerging): "What information do I leak every time I spend?"
This shift reflects a broader realization that what works for DeFi does not necessarily work for consumer payments.

● The Hidden Tradeoff Behind Self-Custodial Payments
Users thought they were getting self-custody and financial freedom, but often received self-custody and radical transparency.
The debate is shifting from custodial vs self-custodial to public vs private settlement, and ultimately from wallet ownership to data ownership.

● Two Competing Design Philosophies Are Emerging
As the market shifts toward privacy, crypto payments are beginning to split into transparency-first and privacy-first settlement models.
• Transparency-First
Most existing card infrastructure is built around public ledgers, where transactions remain auditable, verifiable, and visible on-chain.
This model is represented by @RedotPay, @KASTxyz, @ether_fi, @useTria, @gnosispay, @ready_co, @Solayer_Pay, @raincards, and other cards built on public settlement rails.
• Privacy-First
A newer category is emerging around private-by-default payments and selective disclosure.
Projects exploring this direction include @payy_link, @BleapApp, @cryptoBingCard, @LasoFinance, @offgridcash, @sat_pay, @pintopay_me, and @Haven_Hn_.

● The Market Is Starting To Price Privacy
If this trend continues, capital may increasingly flow toward privacy infrastructure, ZK payments, and alternative settlement rails.
• Privacy Infrastructure: Projects building confidential transactions, identity abstraction, and private settlement layers.
• ZK-Based Payments: Projects using zero-knowledge proofs, selective disclosure, and confidential accounting.
• Alternative Settlement Rails: @LightLinkChain, @aztecnetwork, @hinkal_protocol, @0xprivacypools, and @Starknet privacy initiatives.
AI has dramatically reduced the cost of wallet clustering, identity discovery, and behavioral analysis, accelerating this shift.

Today, crypto cards compete on rewards, yield, availability, and fees; tomorrow, they may compete on privacy and identity protection.
Users are beginning to evaluate not just what they earn, but what they reveal.
Crypto payments have largely solved accessibility and rewards; the next battleground is infrastructure that combines self-custody, compliance, and privacy.
Better banking isn't about replacing the system. It's about improving it, starting with stablecoins.
Biptap CEO @jonathanlowyt, on why stablecoins give Biptap the edge over traditional fintech, increasing transfer efficiency for cross-border payments while the rest is still stuck on legacy rails.
morning: deal call. afternoon: book chapter. evening: investor dinner. this is not a flex. this is a warning. if you want this life, you need to want all of it.
One app for your bank? One for crypto? One for the card? That's not banking. That's admin work.
An omnibank replaces the stack — fiat, crypto, wallets, and cards live on the same app, under the same login.
