I read that one of the best ways to preserve a seed phrase is to write it on a piece of paper and keep it in a safe place... Somewhere safe could be in your home out of the reach of family members and friends, it could also be a safe deposit box. But not everyone are financially buoyant to afford the services of a deposit box.
I believe we must have seen or heard about fire outbreaks, where buildings are completely erased by fire. Imagine if the owner or occupant of such a building has some Bitcoin assets, and has his/her phone, tablet, laptop and the seed phrase piece of paper in the building and everything was lost to fire. Now, this brings me to the question... Can seed phrase be memorized? It's advisable to memorize seed phrase?
Of course you can, I think memorizing the seed phrases is fine and I don't think there's anything wrong with that.
But if memorizing it in your mind is the only thing you do to store your seed phrases, that's reckless and overconfidence.
Slow years our brain will definitely experience a decrease in its performance and we can also be hit by a disaster that causes amnesia. Who knows?.
There are many ways to store our seed phrases such as storing them digitally, writing on paper, printing/engraving them on metal or other media.
It depends on our creativity to secure the seed phrase that we have.
There have been many discussions in this forum which have made and summarized any ways we can store the seed phrases we have.
