KAST, Bybit Card, ether.fi Cash: official fee schedules not confirmed from their pages on 2026-11-07 — cells marked “Not published”; check each provider’s current terms before applying

When you search “redotpay vs kast” or “redotpay vs bybit card,” you want numbers verified against official pages — not marketing copy. This comparison shows only figures we could confirm from each card’s own official site on 7 November 2026. Where a competitor’s fee schedule was not accessible for verification, the cell reads “Not published.” That is not a judgement on the product; it means we could not check it on that date. Verify current terms at each provider’s help centre before applying.

How do these crypto and multi-currency cards compare?

Five products appear most often alongside RedotPay in comparison searches: KAST, Bybit Card, ether.fi Cash, and Wise. The first three are crypto-funded spending cards; ether.fi Cash is a Visa credit card backed by DeFi collateral rather than a direct spend-your-crypto model; Wise is a fiat multi-currency account that some crypto holders use alongside a crypto card. The table below uses only figures confirmed from official pages on 7 November 2026.

RedotPay vs KAST: who is each card for?

“Redotpay vs kast” is the most frequently searched comparison in this space. We could not confirm KAST’s fee schedule from an official page on 7 November 2026 — the KAST app appears to be a JavaScript-rendered product that does not expose a publicly readable fee table at the URLs we checked. We will update this section when KAST publishes a linkable fee schedule.

What is verified for RedotPay: a 1% fee on each crypto top-up, 0% FX on purchases in the card’s denomination, 1.2% on purchases in other currencies, and — with the Pro tier — 3% cashback on Apple Pay and Google Pay spend up to US$18 per month. If KAST publishes a comparable breakdown, the total cost per transaction will depend on the same two variables: the conversion rate at top-up and the FX rate at the point of purchase. Check KAST’s official site for current terms. For more on RedotPay’s fee structure, see the RedotPay fees page.

RedotPay vs Bybit Card

Bybit Card is the natural option for people who already hold assets on the Bybit exchange, since it draws directly from a Bybit balance without a separate top-up step. Bybit’s help centre pages were not accessible via automated requests on 7 November 2026, so we cannot confirm current fee figures here. If you hold assets outside Bybit, check whether Bybit Card accepts direct on-chain deposits, or whether a transfer to Bybit is required first.

Country availability matters: Bybit operates under regulatory restrictions in several jurisdictions. If your country is on Bybit’s restricted list, the Bybit Card will also be unavailable. RedotPay’s restrictions are separate and published at Help Center article 14254838 (checked 2026-11-07). Check both lists for your country.

RedotPay vs ether.fi Cash: different models

The ether.fi Cash card works differently from the other products here. Its documentation describes it as “a Visa credit card that you can load with your balance” by borrowing against your ether.fi DeFi holdings — it is a credit product, not a spend-what-you-deposit card. (ether.fi documentation, checked 2026-11-07.) The fee schedule and credit terms were not accessible for verification on 7 November 2026; check ether.fi’s current help centre.

Who should consider ether.fi Cash: users who have a large liquid staking position and want to access liquidity without selling. Who should consider RedotPay: users who want to convert and spend stablecoins (USDT, USDC) or other crypto directly.

RedotPay vs Wise: when does each make sense?

Wise is a fiat multi-currency account, not a crypto card. The Wise US card costs US$9 to order and offers the first US$250 of monthly ATM withdrawals at no Wise fee; Wise states it uses the mid-market exchange rate, though the specific percentage was not stated on the page fetched on 7 November 2026. (wise.com/us/card, checked 2026-11-07.) Wise is not available in all countries.

Wise works well when you need to hold, receive, or send multiple fiat currencies at close to the mid-market rate. RedotPay is designed for people who have crypto and want to spend it without first converting through an exchange. Some users run both: RedotPay for crypto-funded purchases, a fiat card for local or salary-linked spending.

Which of these cards can I get in my country?

Your country of registration determines which cards you can apply for and whether a physical card can be issued. For RedotPay, the official restrictions are published and regularly updated. Country-level availability for KAST, Bybit Card, and ether.fi Cash was not confirmed from their official pages on 7 November 2026; check each provider’s terms.

United States Service not available Available Not confirmed HC 10339263, 2026-11-07

How do I choose between these cards?

The right card depends on four questions, in roughly this order:

Question What to check
Is the card available in my country? RedotPay: supported-countries page; others: check each official site
What type of balance do I have? Stablecoins / crypto → crypto card (RedotPay, KAST, Bybit Card); DeFi yield position → ether.fi Cash; fiat → Wise
Do I need ATM cash withdrawals? RedotPay physical card: 2% (USD card, ≤US$10,000/month); Pro Annual waives up to US$1,000/month; Wise US: first US$250/month free
Do I use Apple Pay or Google Pay? RedotPay: supported (card upgrade may be required; RedotPay Apple Pay page); others: check official site

If you already use the Bybit exchange and want to skip a separate onboarding, Bybit Card is worth checking if it is available in your country. If you need a card for everyday fiat spending and exchange rates matter more than crypto access, Wise may suit better. If you want to spend stablecoins or crypto without leaving your wallet environment, RedotPay is designed for that use case. See the RedotPay card review for a detailed look at the pros and cons.

FAQ

Which is cheaper, RedotPay or KAST?

KAST’s current fee schedule was not confirmed from an official page on 7 November 2026, so a direct numerical comparison is not possible here. What is verified for RedotPay: a 1% fee on each crypto top-up, 0% for purchases in the card’s denomination, and 1.2% for purchases in other currencies. (Help Center 10622095, checked 2026-11-07.) When comparing any two cards, total cost per transaction depends on the same two variables: the conversion rate applied at top-up and the FX rate at the point of purchase. Check KAST’s official site for current terms before comparing.

Is RedotPay available where Bybit Card is not?

The two products have separate country restriction lists. RedotPay does not serve the United States, Japan, Mainland China, and several other countries; the full list is at Help Center article 10339263 (checked 2026-11-07). Bybit Card’s availability depends on Bybit’s own country policies, which we could not confirm from official pages on that date. If your country is outside both restricted lists, either card may be an option. Verify by checking each card’s current supported-countries page — including RedotPay’s supported countries page.

Is there a RedotPay alternative for India?

India is on RedotPay’s card-issuance restrictions list — residents can create an account but are not eligible for either the virtual or physical card. (Help Center 14254838, checked 2026-11-07.) Whether KAST, Bybit Card, or ether.fi Cash are available to Indian residents was not confirmed from their official pages on 7 November 2026. Wise’s US card page does not list India as a blocked market, though per-country spend limits apply. For any crypto or multi-currency card product, users in India should verify compliance with Reserve Bank of India guidelines before applying; this article does not provide legal advice.
