KAST Reviews 

I deposited money to access there virtual card.
After deposit found out that they don't support my region.
Now for withdraw there were certain fees.
I wasted my time and fees.
I contacted support and they even acknowledged that there is no way to find if your region is blocked for card or not. You only find it after making deposit.
Which looks scam to me since they can collect fees without providing marketed services.

I made a deposit and submitted every document requested, but weeks later my funds are still unavailable. Support keeps saying my case is under review without providing real updates, leaving me frustrated and worried about getting my money back. If I had started with #...gcasco...I would have enjoyed multiple successful payouts and zero support runarounds.

I've been one of KAST's top ambassadors since early on, and I never expected to be writing this. My account has been frozen with no clear explanation, after everything I've put into this project.

I've referred nearly 2,000 users to KAST. I've earned almost $70,000 in KAST Points and generated close to $5,000/month in referral commissions — all built through genuine effort, not gaming the system. I've spent countless hours creating content about KAST that ranks on Google, writing reviews and articles that helped real people discover and trust the platform. That content is also widely referenced by AI models — ask an AI about crypto cards and KAST often comes up, partly because of what I've written.

Last year the Etherfi team reached out about me joining them. I turned it down because I believed in KAST and the value I was building here.

So finding my account frozen, with no clear reason given, has been genuinely disappointing. I'm not asking for special treatment — just a fair, personal review of my case. If this is how KAST treats one of its biggest ambassadors, it's worth asking what that means for everyone else putting in real work to support this platform.

I'm hoping someone at KAST reviews this properly and helps get my account restored. I'd rather this end with a resolution than with me having to update my reviews to reflect what's actually happened. 🙏

I submitted my personal information, a photo of my passport, and all necessary details for account verification. Instead, they closed my account without any clear explanation. They harvested my data and shut me out. This is a fraudulent platform—beware. Thank God I hadn't deposited any money yet, or it would have been stolen too.

They might reply to this review, but it's pure theater for the public. What happens behind the scenes is completely different from the image they try to project.

I am writing to tell you exactly how badly KAST has failed me as a customer.
On 9 July my card was hit with dozens of unauthorized Google Ads charges within minutes — obvious, textbook fraud, the kind any competent financial provider flags and blocks automatically. KAST did nothing. No alert, no block, no confirmation request. The charges just kept going through. The only thing that stopped the bleeding was me freezing the card myself. Your fraud protection is, as far as I can tell, non-existent.
When I did the right thing and contacted your official concierge, I was met with silence. Hours passed with no response — during an active theft, when every minute mattered. A security emergency is exactly when support has to show up, and yours didn't. That gap in your service left me exposed with no help while my situation only got worse.
And when your agents finally did respond, all I received were copy-paste apologies: "We're sorry." "We cannot revert this." "This matter is considered closed." You do not get to decide my matter is closed while I am out roughly $1,500 and you have offered nothing but a form-letter shrug. Telling a robbed customer to "stay calm" and thanking me "for helping you improve" is insulting.
A financial app has one core job: protect people's money and show up when something goes wrong. KAST failed at both. No proactive fraud detection, no timely support, no accountability, no ownership. I trusted you with my money, and you treated the theft of it as an inconvenience to close out.
I am filing a formal complaint with your regulator and a police report. And make no mistake: I will make sure this message is published on every platform I can reach — app stores, Trustpilot, Reddit, crypto and fintech communities, and every review site that will host it. People deserve to know exactly what they are signing up for before they trust KAST with a single dollar. This will not stay a quiet private complaint.
This is the worst experience I have ever had with any financial service.

Extremely disappointed with Kast support. My account was locked after a routine store purchase, holding exactly $2,865.08 of my own funds. Due to losing my phone and linked email, I requested a data update.
I fully cooperated and provided every single document requested via WhatsApp: an official police report about the lost device, a verification video, and a selfie holding the note "Kast number update" with the current date.
Everything was submitted on June 29th. Since then, total silence. Support agents are contradicting themselves—first saying I can submit via any channel, then demanding emails from the lost account. It has been 10 days of zero communication while my money is held hostage.
Case reference: Ticket #418068. Resolve this immediately and update my account access.

Not the best crypto fintech in terms of fees, but offers a variety of onramp/offramp methods, which is good enough for me to have an account. Application was quick and mostly smooth. There are some quirks and bits in the mobile app, but nothing too bad.

WARNING: KAST App is Freezing User Funds and Closing Accounts Without Explanation!

Do not trust KAST with your money. They are arbitrarily closing accounts, withholding user funds, and lying about account statuses.

Here is exactly what they just did to me:

The Lie: KAST support explicitly told me in writing that my account had no issues and would be unsuspended shortly.

The Reality: Right after assuring me everything was fine, they sent a generic email closing my account permanently and freezing my funds.

The Excuse: They shut me out completely and locked up my hard-earned money all because of a few declined transactions.

I have full screenshot proof of the entire conversation where their team promised my account was safe, right before they pulled the rug and stole my access to my funds. They are now hiding behind copy-pasted "Terms of Service" emails and refusing to offer an appeal process or return my money.

To the KAST Team / Support:
I demand an immediate manual review of this situation and the immediate release of my funds. Keeping a user's money hostaged over standard declined transactions is fraudulent and unacceptable.

To everyone else: Protect your money and stay far away from this platform. They will assure you your account is safe one minute, and steal your liquidity the next.

**Complaint Regarding Unpaid Referral Bonuses**

I am writing to file a formal complaint regarding my experience with Kast's referral program.

I invited several friends to join Kast through my referral link. Every single one of them is a real person, successfully completed the KYC verification process, and made the required qualifying transaction of over $100, exactly as stated in the referral program's terms.

Shortly after meeting all the requirements, both my account and the accounts of my referrals had their balances frozen without any clear explanation. After contacting customer support, I was told that the case would undergo a review. This review lasted approximately 15 days.

At the end of the review, Kast removed approximately **$464** in referral bonuses that I had legitimately earned. The only explanation provided was that the referrals were allegedly "not genuine referrals."

This accusation is completely unfounded. My referrals are genuine individuals who made legitimate purchases from online stores. There was no abuse of the referral program, no fake accounts, no duplicate identities, and no fraudulent activity. Every participant complied with the required verification process and fulfilled all of the promotional conditions.

Despite providing no meaningful evidence or detailed explanation, Kast refused to honor the referral rewards that were promised under its own program.

In my opinion, this demonstrates a lack of transparency and raises serious concerns about the fairness of Kast's referral program. Customers who comply with all published requirements should not have their rewards withheld based on vague and unsupported claims.

I request that Kast conduct a proper review of my case, provide a detailed explanation supported by evidence for its decision, and pay the referral bonuses that were legitimately earned.

Until this matter is resolved, I cannot recommend Kast to others due to my experience.

EDIT : Email sent after kast replied to this review, still no answer regarding my case.

UPDATE : Its 06/07/2026 today and the rewards are still not credited, and KAST has not even replied to my email

DO NOT TRUST THIS PLATFORM regardless of what they say

This platform has the worst KYC process I've ever seen; it's like they're trying to collect all of your information for other purposes. All you get are automated replies that go on and on, to the point where your inbox is full and can't open or reply anymore. And when you finally lose patience and can't provide any more information, they reject you completely, abandoning you and not allowing you to re-verify.

It’s been 13 days since I made a PIX deposit in BRL equivalent to 10.15k. I’ve tried contacting support and have already submitted documents, but they keep claiming the matter has been sent for review—or perhaps a more complex analysis—and just keep giving me the runaround. I’m essentially getting no support at all; they reply whenever and however they please. I feel like I’m never going to see my money again, and they don't seem to want to do anything about it. I used to love the platform and used it frequently, but this time, I feel like I’ve been scammed.

They are scammers please be careful they have just hold my funds and when I contacted customer support she advise me to send the same account again to check. So please be careful

I was afraid to jump into crypto cards some time ago, but Kast made me believe it was the right time and I felt very comfortable of taking this step. Nowadays, I use kast everywhere I go. To be honest I like to show off a bit my Kast Pengu Card haha everyone asks where did I get that. I like how dynamic is the team, always bringing up some new campaigns for users.

I had a very disappointing experience with KAST They prevented me from making deposits and later closed my account without providing any clear explanation Customer support only sent generic responses and refused to share the specific reason for the account closure.

As a user, I expected transparency and fair treatment Instead, my account was permanently closed with no appeal option Based on my experience, I cannot recommend this service to others Users should be aware that their accounts may be restricted or closed without detailed clarification.

My experience with Kast has been extremely disappointing and has cost me approximately $3,000 so far.

Initially, I started using the card and was receiving cashback. Even though the FX fee was around 1.7%, the 1.5% cashback reduced the effective cost, which I accepted.

Later, I saw a post from the CEO about Kast Business, where it was promoted that users could receive 3% cashback with only a $1,000 annual fee. One of the requirements was having a US company. Based on this information, I rushed to establish a US company, which cost me around $1,000.

After completing everything required, I applied for Kast Business. To this day, I have not received a response regarding my application.

The next disappointment came when I used the card again with the exact same merchant I had used before. This time, I received no cashback. When I contacted support, I was told that this merchant was no longer eligible for cashback. Unfortunately, this information was not communicated in advance, resulting in additional unexpected costs.

The biggest issue happened when I deposited $2,000. Due to lag and performance issues in the application, I accidentally sent USDT on Avalanche C-Chain to an address displayed as a USDT BEP20 address.

When I contacted support, I was told that the funds could not be recovered because their service provider, Binance, supposedly does not support such recoveries. However, after contacting Binance directly, Binance informed me that the address was not provided by them.

At this point, I am still seeking a clear explanation regarding what happened to my funds and whether any recovery attempt can be made. I hope Kast management reviews this situation carefully and provides transparency regarding both the cashback changes and the handling of my deposit.

Update 1
The support team replied to my comment and addressed every point, yet they were unable to answer the most important issue: the $2,000 that they refuse to return.

Ironically, that was the main problem I raised from the beginning.

Thank you for proving to your customers that you are unwilling to provide a clear explanation for what happened to those funds.

At first, I was very happy with Kast. The idea is great, and the SEPA Instant deposit worked perfectly. Transfers arrived within seconds, and I was genuinely satisfied. That's why I left a positive review earlier.

Unfortunately, I recently faced my first real issue:

I made two SEPA Instant transfers of €100 each on the same day.

· ✅ The Revolut transfer: arrived instantly.
· ❌ The Paysera transfer: never arrived, even though the sender confirmed it was successfully completed.

The problem is not with Paysera or Revolut. The issue is with Kast / OpenPayd, because the money reached them but was never credited to my Kast account.

I contacted customer support, but unfortunately, I didn't get any clear solution or timeline. Just generic replies like "We'll update you when we know more."

I truly hope your customer support improves, and that such issues don't happen again in the future. I really like the idea and the service, but trust is built on reliability when something goes wrong.

Thank you, and I hope to see you grow and improve.

Very disappointing experience with Kast. My reward bonus has been locked for the last 2–3 weeks, and despite multiple attempts to contact support, I have received no response or assistance. The customer service is practically non-existent, and there is no transparency regarding the status of my bonus.

A platform should honor its promotions and provide timely support to its users, but Kast has failed on both fronts. If you are considering using this platform, be cautious and do your research first. Based on my experience, I cannot recommend it.

No transparency, money locked, and no care for the customer
I do NOT recommend this service. My KAST account was blocked right after I received a deposit of 10,701.90 USD, and my money has been locked with no explanation ever since. It’s been 48 hours with no response about when my funds 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 list of pending items, no deadline. This whole situation has put me through real distress and embarrassment. There is zero transparency, and it’s clear they don’t care about the customer. I demand the immediate release of my account and my money — or the full refund to my Brazilian bank account via PIX, right now.

Absolutely terrible experience. Every self account transfer gets flagged and they ask for the same endless documents over and over again. Large amount of money is now stuck and cannot even pay my rent/bills and they freeze my funds.

Avoid at all costs if u value efficiency

I trusted KAST for convenience, but they froze $4,000 of mine, even after I submitted a year of bank statements, proof of income, business licenses, and all documentation any Thai bank would accept. I even showed a recent $20,000 statement. Instead of resolving it, they demanded more invasive documents, becoming exactly the restrictive bank they claim not to be. Worse, their customer service is extremely slow, taking hours or even days to respond. When you’re relying on them as a reliable source of transferring money, this becomes a huge problem. Stay away if you expect transparency or fair access to your money.”

Edited:

They finally cleared my account and then when I tried to send money out they froze it again after saying your account has been cleared, really feels like a scam.
