I’ve never used it but most people seem to like the auto DCA into cold storage. I am concerned with that feature though because I don’t see how they can do it without your xpub. If you need to give them your xpub, you are potentially centralizing your bitcoin wallet funds in a database that can be compromised. But don’t trust what I say because I’ve never used it and I don’t really know how it works. I could be wrong.
