KAST Reviews 

I registered an account with this company to make online purchases. They suddenly blocked my account and demanded various documents, ranging from a video selfie with my documents to a video with my passport and visas. I provided all the documents I could, but they still weren't in a hurry to unblock my account and return access to my money. I deeply regretted dealing with this company and I don't recommend anyone to do business with them.

Avoid to use kast - they can block you for no reason and also use your deposits - I've been using kast for daily market transactions, they suddenly lock my account when i was at market, for "security" they said, but i do nothing wrong, plus my deposit they freeze.

after tons of provided information at whatsapp support, it's like bot asking same questions again and again, with fake "forwarded to our team" messages.

so, kast is big scam. avoid using it.

I deposited 2 times 100 euros via sepa instant transfer and later i did not received the third transfer losing my money. i was scammed and live chat did not helped me. i want my money back

UPDATE
The deposit arrived all good

Great usability and user experience. I especially appreciate 'kimisfast' for kindly helping me with my onboarding.

It’s one of the best crypto cards for USD spending. The rewards are simple and intuitive, and the app design feels sleek and premium. The Pengu card is also one of the bset physical cards that’s genuinely worth showing off.

I am a 1 year user of KAST, been onboarded by the team during an event back in 2025, the team was super supportive and friendly I made the switch from another service provider.

Pros:

1) Application UI is great and always improving, maybe too much lol always updating (don’t get me wrong that’s a good sign but too many)

2) It saved me!
Freedom to use stable coins anywhere, cash back rewards and Apple Pay support saved me in my travel trips due to limits imposed on my country’s banks credit cards abroad. When I had to extend my stay didn’t have other options but KAST was the key!

3) Their concierge service always helped me on issues via WhatsApp on a timely manner. Especially when I had an issue with Apple Pay not accepting adding any new HongKong cards, the got me covered with a new card that was accepted.

4) Got Physical and Virtual with Apple Pay support,

5) Crypto on chain, bank account and bank transfers.
Cons:

1) Not really a con but it was overwhelming a-bit to submit documents to KYC but now I know they make sure security is top notch.

2) Payment links to accept payments from the US.

3) Need more rewards to existing users or I am just greedy 😅

I had a terrible experience with Kast.
They requested an enormous amount of personal information from me: ID documents, biometric data, proof of physical address through a utility bill, and even proof of source of funds. After submitting everything, the banking service was never activated. For weeks, I kept receiving the same responses: “try again tomorrow” and “our team is working on the problem.”

After more than a month of useless waiting, I asked to close the account and permanently delete all my data. At that point, I was told that my data would still be retained for 5 years.

Very negative experience. I strongly advise everyone to be extremely careful before sharing such sensitive information with this firm.

I’ve been a Kast user for about 6 months, and the experience has been awesome. Now, every time I get my paycheck, I convert part of it into crypto just by making a SPEI transfer. I also went to Colombia, and the card helped me a lot with making payments

I moved all of my idle USDT to KAST after meeting the team in Dubai and couldn't be happier. My first time ever tapping to spend stables and now I'm doing it all over the world, with 0 issues. Also love the vaults giving over 4% on my available balance, and the KAST rewards too!

Excellent service, using it each time I pay abroad and works with my wallet and Cashback is instant

KAST is an amazing global money app. I use it globally. I would like them to offer more direct EUR or EURC integrated card PoS services as I'm based in the EU mostly. Overall, it's superb most of the time. Low fees, near instant international transfers globally in fiat and instant in crypto/stablecoins

Excellent experience with KAST cards so far. Fast transactions, high security, and very reliable service. Everything works smoothly for online payments. Definitely one of the best card services I’ve used.

The product works really well and the app looks aesthetically pleasing which made my experience smooth. However I think KAST should be usable using Samsung pay.

I've been using KAST since November 2025 , very satisfied

perfect app honestly

The only best crypto card

i use it about 1 year now
great card and good benefit
just they were late in launching their token
we are waiting .

I tried it and was great and still gonna keep using it because it has all i need.

I made my first wire transfer through KAST.xyz, a routine payment of a few k USD to American Express to pay my own Amex card bill.

They immediately sent absurd compliance questions asking what the “exact purpose” of the payment was and “how will the customer be using these funds.” The recipient is American Express, retards! The purpose is paying a credit card bill. American Express will use the funds by crediting the card account, which is the entire point of paying a card bill. This is not complicated.

They also asked for source of funds/source of wealth documentation for a normal card payment on the very first wire I made with them. Compliance checks are one thing. Mindless copy-paste bureaucracy that delays ordinary payments and asks nonsensical questions is another.

If a platform cannot process a straightforward wire to a major regulated credit card issuer without making the customer explain what American Express does with credit card payments, that says a lot about the quality of their operations.

so really bad my account can settle really bad
