I know how wallet and things work. My point is casa is giving a fake sense of security. If I can keep 2 keys safe of a 2 of 3 wallet or 3 keys of a 3 of 5 key wallet then why can't I keep all the keys safe? I can.
Definitely.
Let’s focus on another aspect though. Supposing you wanted to create a 2-of-3 or a 3-of-5 on your own, which is basically a solid system, would you choose to make one of the keys a hot key which is backed up on the cloud? On any cloud.
