Hi,
go to Trustpilot and look up the customer reviews for Kraken, then check out the 1 star ratings. There is a flood of them complaining about having their accounts closed for not apparent reason.
Don't trust the reviews on TrustPilot too much. Good can be bad and vice versa here.
Anyway, there will be no exchange that has perfect reviews. Just look at their reviews on applications, whether in the playstore, appstore or others, there will definitely be bad reviews based on their security. So, this doesn't just happen to Kraken.
Generally I've mostly read good opinions on them, they are often brought up when the subject is trustworthy exchanges. I just didn't know what to think about that absurd amount of negative reviews, and something seems fishy about it.
But what is certain is that Kraken is a top exchange. They have a good reputation so far. It's not perfect 5 stars, but their service, live support, display, and several other things related to Kraken are actually very good. There's no need to hesitate. As long as we can really use and optimize this application, there's actually no problem. And we learn some of the T&Cs so we can use them appropriately. Then it won't be a problem.
Unless it is a low-cap exchange or a new one, we need to be alert. But this is Kraken.
