I start a crypto-card comparison with one question: who controls the money before it reaches the shop? A merchant voucher, a company-held card and an exchange-linked card give different answers. Profitstride's comparison, published on April 5, 2026, favoured wallet-style cards for everyday privacy and Bybit's European option for people comfortable verifying their identity. Neither preference settles the question of access to your funds.
How crypto cards differ
A gift voucher turns cryptocurrency into credit at a particular merchant, so you choose the shop before spending. A payment card lets you pay through a card network, subject to its acceptance and the provider's arrangements. An exchange-linked card draws on money held in your exchange account, making that account part of your everyday payment setup.
The comparison covers gift cards, wallet-style cards advertised without KYC, and exchange cards requiring KYC. KYC means "know your customer": identity checks that connect an account to a person. Custody is a separate question: who controls funds while they wait to be spent? Less identity checking does not necessarily give you more control over that money.
I find that distinction more useful than treating every card-shaped interface as the same product. An occasional purchase needs less flexibility than recurring expenses, and a cheaper payment route may require more personal information and a closer relationship with the provider.
Buying a voucher through Bitrefill
Bitrefill sells merchant vouchers for cryptocurrency, including Amazon and Carrefour gift cards, Steam vouchers and eSIM products for travel. An eSIM connects a compatible device to a mobile service without a physical SIM. The voucher purchase gives you credit to redeem with the selected merchant rather than a balance you can spend anywhere.
For me, that makes vouchers a better fit for a planned purchase. Choosing one before deciding what to buy risks leaving value stranded at a retailer you do not need. Check the merchant, currency and redemption conditions before paying; a completed crypto transfer does not establish that the voucher suits your purchase.
To buy a voucher:
- Open Bitrefill's catalogue.
- Select the Steam gift card, or the merchant voucher you intend to use.
- Add the selected voucher to the cart.
- Choose a supported payment method at checkout: Lightning, Bitcoin, Ethereum or stablecoins.
- Complete the purchase to receive the gift voucher.
Lightning is a network for Bitcoin payments. Stablecoins are crypto tokens designed to track a reference value, commonly a currency, but they still carry issuer and market risks.
The creator describes most voucher platforms as requiring no identity verification, delivering vouchers immediately and generally suiting occasional consumption. That is their assessment, including the limits on large or recurring payments. Unlike a card account, the arrangement centres on purchase and delivery rather than leaving a spending balance with a provider. I would judge the voucher by whether I wanted to shop at that merchant anyway.
What no-KYC cards put between you and the payment network
Bancus and Xkard are the wallet-style examples. In the creator's account, an intermediary company holds the formal relationship with the payment network and is the cardholder. The company undergoes KYB, or "know your business", rather than the individual completing the direct identity checks required of an exchange customer. That is the explanation behind "no KYC", not a claim that nobody in the arrangement is verified.
I would not read it as proof that no records exist. The intermediary still has a relationship with the payment network, and skipping a personal onboarding check does not establish what information other participants collect.
Xkard is accessible through a web browser. Its described balances are USDC, USDT or dollars, with Apple Pay and Google Pay support. The card is held in the associated company's name rather than the user's. Bancus is another option, but the creator had not used it. Its displayed USDT deposit address on BSC establishes neither successful payments nor reliable support.
The phrase "linked to a wallet" deserves care. Funding a card from an external wallet does not mean you retain control of the spending balance. The creator warns that these providers rely on third parties, require trust in their custody and offer poor customer support. They prefer the category's everyday convenience to merchant-specific vouchers, but not for long-term security and stability.
I see the practical problem as access: if a payment fails, you need the provider to resolve it. Less personal information at signup does not remove that dependency.
Comparing the quoted fees
The quoted charges favour the exchange-linked option on cost, but they do not all measure the same part of a purchase.
| Option | Fee quoted in the source | Qualification |
|---|---|---|
| Gift vouchers | 2% to 2.5% | Possible conversion cost; voucher pricing could also affect value |
| Bancus | 4% | Described as an average "flat tax" fee |
| Xkard | 2.3% to 5.5% | On-screen range; depended on the card used |
| Bybit Europe | 0.9% plus 0.5% | Card fee plus a foreign exchange fee over the Mastercard rate |
Xkard's upper endpoint is disputed within the source: the spoken figure was 5%, while the on-screen note used the higher endpoint in the table. I would check the tariff for the specific card rather than assume either applies.
Voucher pricing can also mean paying more than the shop value or receiving a smaller discount. The conversion charge alone may therefore understate the cost. Compare the amount leaving your wallet with the purchasing value you receive.
For cards, check what triggers each charge. A foreign exchange fee is different from a basic card fee; listing both does not establish that every purchase incurs both or that the list covers every possible cost. I would compare a planned purchase in its spending currency, not rank products solely by the smallest percentage.
The creator considers Bybit cheaper than the wallet-style examples and advertises cashback of up to 10%, with qualifications about the reward currency and minimum conversion threshold. "Up to" is a ceiling, not a return promised on every payment. Eligibility and redemption terms determine whether the reward is useful for spending you already expect to do.
Applying for the Bybit card
Bybit's Mastercard product uses an associated card issuer. In the European arrangement described by the creator, regulated partners may manage technical issuance and electronic money. The Bybit brand does not mean the company directly holds every licence involved.
The card spends from the user's exchange balance, converting cryptocurrency into fiat when used so the merchant receives a conventional payment. Fiat is government-issued money, such as euros. Physical and virtual versions are available under conditions that differ by country. At the time of the comparison, the creator said the card worked in Spain and favoured the European arrangement for Spanish residents who accepted full identity verification.
I can see the convenience of keeping the exchange account and payment function together. It also means card access depends on the exchange relationship, including its identity checks and access rules.
To apply:
- Sign in to your Bybit account.
- Complete the account's KYC requirements.
- Open Finance Cards.
- Select Bybit Crypto Card.
- Start the card application from the card page.
- Complete the requested identity and address checks.
- Select Mastercard once the required verification is complete.
- Accept the terms and conditions to complete the application process.
An application button is not a guarantee of approval. Read the eligibility conditions before depending on the card as a payment method. I also keep ease of application separate from safety: a straightforward process says little about the risk of leaving money with the service.
Tax reporting and privacy are different issues
Hacienda is Spain's tax authority. CRS, DAC8 and CARF are tax-information reporting frameworks, not rules that decide whether an individual owes tax. The creator argues that voucher platforms are not financial institutions and do not report through the frameworks discussed, and that company-held card intermediaries do not automatically report through CRS or CARF. These are their legal interpretations, not verified determinations for every provider or transaction.
I would not equate "No personal KYC", "no automatic report" and "no information can be obtained". Each describes something different. The absence of automatic reporting does not remove the obligation to declare gains under Spain's personal income tax, IRPF. A provider may also have to answer an individual information request from the tax authority, limits the creator acknowledges.
Their suggestion that a generic name could prevent records from being connected to a user is not a dependable privacy method. It assumes the onboarding name is the only possible connection and does not establish what information a provider or authority could obtain.
For Bybit, the creator distinguishes an account tied to a Seychelles entity from the European arrangement. They claim the former does not file Spain's forms 172 and 173 or enter European automatic reporting through DAC8. Their European claim is conditional: that version would probably fall within DAC8 and share tax information with Spain.
I would identify the legal entity in the account agreement before relying on a statement about the brand. Reporting depends on that entity and the applicable rules; a conditional claim should remain conditional.
Spending cryptocurrency can involve a disposal, with tax treatment dependent on circumstances and jurisdiction. Keep purchase and spending records, and seek qualified guidance if the treatment is unclear. Privacy features do not settle those obligations.
Custody remains a risk with a convenient card
The creator favours the regulated exchange-linked arrangement over offshore-style intermediaries for safety, but also suggests Bybit users would face no custody risk. I disagree with that conclusion. An exchange still controls funds held with it, and regulation does not guarantee uninterrupted access.
Regulation concerns rules and oversight; custody concerns control of the money. Even a regulated relationship can expose users to account restrictions, service interruptions or provider failure. For wallet-style cards, the creator's advice to deposit only what is needed for expenses follows from the custody and support concerns already described.
Vouchers create a different dependency: the merchant credit must arrive and work under its redemption conditions. Check withdrawal and refund terms before funding a card, too. A balance trapped in one payment route can become unusable when that route stops working, even without a permanent loss.
I would apply ordinary wallet precautions regardless of the card's privacy claims. Verify the site address before connecting a wallet, inspect approval requests and avoid permissions you do not understand. Never give a card service a private key or recovery phrase; those credentials control access to the wallet's funds.
A small initial amount limits exposure while you confirm the process. It does not prove reliability. One successful payment establishes neither long-term solvency nor consistent access to funds.
Check what happens when a payment fails
Read the account agreement for the named company, the issuer's role and the rights attached to the spending balance. A product marketed as a wallet or card can leave those relationships unclear. Written terms give you something more concrete than a broad promise of anonymity or safety.
I would then look for the failed-payment process: how reversals work, who handles a dispute and whether support has a documented route for resolving it. This is where convenience matters most, because an easy checkout is of little help when you need a payment corrected.
For an exchange-linked card, inspect the conversion record available after a purchase. It should let you understand which asset left the account and which payment it funded. For vouchers, retain the purchase confirmation and redemption information until the credit has been used successfully.
The choice between sharing data and depending on a provider cannot be settled by someone else's preference. Before relying on a card, I want its agreement to identify the party responsible for a failed payment and the route for getting that payment resolved.
