Scamming you with massive fees

Fx fees are overtaking cashback. And cashback is even a bet on a future valuable equity. Avoid this card issuer and use something more transparent. U are also selling your coins the moment u deposit into kast which is a taxable event! I am not saying any competitor is better but Kast is really bad

Response from developer

We’re sorry to hear this. We aim to keep fees and rewards clear, and we understand your concern about FX costs and cashback value. You can review our fees here: https://www.kast.xyz/legal/fees. KAST does not provide tax advice, but we encourage users to review their own tax obligations. If you need more help, please contact our concierge team.

Amazing

The best crypto credit card, easy to work and fast.

Response from developer

Thanks for the review! We’re glad KAST is working smoothly for you wherever you are.

KYC chaotique, zero transparence

À éviter si vous recherchez un processus KYC sérieux. Mon dossier a été traité par plusieurs interlocuteurs avec des demandes incohérentes, des exigences qui changeaient constamment et aucune explication claire sur les rejets répétés de mes documents. Après avoir transmis plusieurs documents personnels sensibles, j’ai perdu toute confiance dans leur procédure. Une expérience très décevante!

Financial Freedom

I love the freedom of spending stablecoins everywhere I travel. I love the slick user experience. I love the cashback, especially as a Premium Member.

Highly recommend

After I got referred by BELUGA, I realised how easy Kast made it to spend

The did Swift go?

I used to be able to transfer money to my us account until Swift disappeared. Why?

Awful

Worst customer service ever and the transfers doesn’t work

Too many updates

Stop pushing your damn app every single day Jesus ChrisT. I just wanna check my balance. I don’t wanna upload a new app every single time I look at it

Misleading.

They misled me to believe the card would be linkable to Apple Pay, now they are saying it’s a problem from apples side and they can’t do anything about it after I already paid the card fee.

Scam - blocked

This is one of the worst apps I’ve ever used. I wired money to my account, and immediately after the transfer, my account was blocked. Support told me I’d receive a final review within 2–3 business days, but now it’s the 4th business day and I still have no resolution.

They don’t seem to understand that people have bills to pay and families to support. It’s incredibly frustrating. What’s even worse is that there’s no phone number to call—only email support and automated bot responses.

I strongly recommend that no one use this app. I’ve already spoken with my lawyer about taking legal action, and I’ll also be contacting the App Store to report this experience.

Super zufrieden

Beste App und Debitkarte um Krypto Währungen im Alltag nutzen zu können. Support ebenfalls TOP!

Response from developer

Vielen Dank für das tolle Feedback! Es freut uns sehr, dass du KAST und die Debitkarte für Krypto im Alltag so gut findest — und dass du mit unserem Support zufrieden bist. Danke für deine Unterstützung.

Replaced my bank with KAST

I’ve been using KAST since 2024 and it has basically replaced my regular bank. The app makes stablecoins feel simple and usable day to day.

I also really like initiatives like the Pudgy Penguins partnership and the World Cup competition. It feels like KAST is building something much bigger than just a crypto card.

Excited to see what comes next. It’s been an incredible journey so far!

Must Have

Its cool app to use for spending stable coins if u like crypto and very very innovative

Account blocked and money held with no explanation

do not recommend this. My account was blocked right after I received a deposit of 10,701.90 USD, and my money is being held with no explanation. It’s been 48 hours with no response on when it will be released. I’ve contacted support repeatedly and sent every document requested, yet all I get is a generic “your account is under review” — no reason, no deadline. Zero transparency and total disregard for the customer. I demand the immediate release of my account and my money

Card is no longer available!

My card was working fine, but I’ve got an email, that my card will no longer be available in my region!
EXCUSE ME!!
FIX IT!

App ruim

Estou na tokennation e o app nao lê a cnh digital,
Como pode um app nessa feira com esse tamanho erro?

Response from developer

Desculpe por isso — como você está usando uma carteira de motorista digital, ela pode não ser compatível com o nosso fluxo de verificação em todos os casos. Por favor, envie um e‑mail para support@kast.xyz a partir do e‑mail registrado na sua conta KAST e mencione que você está na Tokennation e que o app não está lendo sua carteira de motorista digital. Nossa equipe vai orientar a forma mais rápida de concluir a verificação.

Do not use

Freezing the funds of my colleagues with no explanation or customer service. Accounts with large balances ahouod not be trusted in here. Avoid this app.

TERRIBLE SERVICE !!!

Stay far away from this app !!!They froze the funds in my account without warning and provided no meaningful explanation. To make matters worse, customer service was virtually nonexistent. Reaching out for help was a complete waste of time, and I was left with no answers and no access to my money.

An app that can suddenly restrict access to your funds and then ignore your concerns should not be trusted, especially if you keep a large balance in your account. The lack of transparency, accountability, and support is deeply concerning. This has been one of the most frustrating experiences I’ve had with a financial platform, and I would never recommend it to anyone.
