Came from eXch alternative thread. I was a regulat at fixedfloat, but I'm glad I stopped using their services after I've seen a surge of people getting flagged in bitcointalk and reddit.
If you deposited coins directly connected to eXch to FixedFloat now, I think there is a 70% probability (at least) that this service will confiscate your money and try to get as much personal information from you as possible.
I don't know how these scumbags from FixedFloat market themselves, but I can guess. Their website and documentation probably boast how they are non-custodial, KYC free, quick, no hidden fees, and absolutely trusted. Did I get it right?
Anytime you see something like that, go directly to their T&Cs, Privacy Policy, and other docs they may have. Search for keywords like "KYC", "AML", "identity", "verify", "verification", "document", "ID", "passport", etc. If you can't find these, still read the docs. Look for the context of where those terms are mentioned and you will probably find out that you agree with the service being able to freeze you out of your money and having to submit all sorts of personal information if you want to get it back.
