This is one of the things that we always worry about when doing KYC anywhere, even at local exchanges where they have registered the legality and securities of the data we provide under the law. However, take a look at what the @bitmover:
-They can sell your data.
-They can share your data with their partners, who can do anything they want with it.
-They can be hacked, like
ledger was.
Whether it's intentional or accidental, isn't it the same if our data is lost or exposed? still, this is related to the loss of our privacy. Meanwhile, in this case, we need privacy and it is unfortunate that the KYC system always endangers its users.
Maybe just with KYC using email without ID or a photo of ourselves, we still have a way to use our backup email. However, if it's KYC with our ID and photo, then this is the dangerous one.
