3. If you keep your keys codes etc in your computer make sure you always have a backup a clone for the drive to be safe.
yes but to be honest for me, I prefer doing physic backup for our private key. like print them out to the paper, and laminating it with strong plastic. then save them in your private place. it will be better to write them one by one for restoring it than let the hacker or somebody take down your PC and steal all of your assets in the future
unfortunately you also have to be careful with natural disasters or fires, my friend has experienced it, the key phrase is stored on paper and at that time there was a fire at his home,
unfortunately, because my friend went out, so he didn't have time to save his property, especially the key phrase, this could be a lesson, we actually have to save our key phrases online and offline, just in case,
and to be online, of course, have to store it in a completely safe place.
