But saving your seeds offline is often said because from the moment you have them online, there is a risk that they will be stolen by hackers, and for that it doesn't matter if Amazon Drive stops its service on Dec. 31, 2023.
Of course, we've already made a point as to what kind of data that should be stored on the cloud and that is, the non sensitive data or files. In this regard, we don't hope to have users who will go ahead to upload or store there private keys and seed phrases online just because, you can access it anywhere and anytime in the world with any Internet device by simply logging on.
The major issues to this is hacking but I don't think that is the only. These files or data are stored for easy accessibility, recoverability, security and leveraging the storage space available on these servers. Now, shutting it down kind of takes all that away and one dumb enough to store there private keys or seed phrase online with hopes to recover and import wallet in the invent of a crash might have just lost everything.
If hacking makes you lose everything and shutting down a service has the same effect, then technically, we could say they are the same thing. Offer the same risk, just different means!
