SardineReviews of sardine.ai

I would not recommend this service.

My experience with Sardine Ai has been one of the most awful and terrible experiences ive ever had with any bitcoin applications ive dealt with so far. What happened was that I created my personal account, gave my full SSN, my full date of birth, my full name, and then I tried making a purchase it was consistently saying "Unable to complete transaction Unfortunately we are unable to approve your transaction" repeatedly. Then, when i contacted support, I got an automated email response saying how they couldn't approve my sardine ai account for no reason at all. I emailed them again, then I got a human response but the response I got was honestly just terrible, they said my account was not approved on the website and wouldnt give me the exact clear reason at all, and when I tried to follow up and ask if I could upload my ID they were ignoring me and not really helping me at all. I then asked them if they could delete my account, my SSN, my personal information, and they had replied but I didnt really understand there response but from what I read they were saying it sounded like they were refusing to delete my personal information. This is just extremely frustrating, concerning, and really risky to me, since sardine ai wouldnt let me set up my account even when I offered to upload my id to support, and they just blocked my account basically completely for no reason, and refuse to delete my account or any information associated with my account at all. They are terrible. Do not use Sardine bitcoin, at all.

It's been 2 days passed from the ordered and still didn't delivered. customer support is terrible.

Slow transfers, hidden costs. They charged me much more for my purchase than advertised. There are dozens of other options out there, use anyone else. I'm obviously not the only one who thinks this either, just look at the vast majority of their reviews! Edit: Today, the 14th of January 2026, I received a response from my review. This response has come THREE AND A HALF MONTHS after reaching out to them. Well done on that customer service /s! Please, anyone wanting to purchase Bitcoin... do so with any other seller to avoid high fees and shoddy customer support!

Tried to make a purchase with US documents and a card. Exchange collected all the information: financial, personal, and biometric, just to deny at the very end. Support never replied, just sent me a letter with my own complaint back.

This is the 5th time sardine has held my crypto i bought through them. Every single time the price was dropping and they waited until the price went back up above my purchase price so they have to pay less for the same amount of crypto i bought. Why do they take my money if they know their liquidity pools are locked. They are not locked for a 300 dollar transaction. Sardine is frauding its customers by waiting until the price goes higher then what we pay so they have to send us less money technically. I cant believe they have the audacity to actually have a fraud department or do fraud protection. How do we get fraud protection from sardine?

DO NOT USE THEM. THEY WILL TAKE YOUR MONEY AND NOT DELIVER YOUR ASSETS. ITS ALMOST IMPOSSIBLE TO REACH A CUSTOMER SERVICE VIA EMAIL. THEY ARE THE ABSOLUTE WORST AND DONT CARE ABOUT THEIR CUSTOMERS.

They know about delays up front but don't make them known until after you've purchased. Your order can randomly be delayed for days at a time and they don't tell you in advance. Stay away if you want your crypto within a few minutes after ordering.
