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?
Well, you sure have a point here but i personally would not advice anyone to try to memorize their seed phrase, but even one must do so, do not do it and rule out the writing down and keeping in a safe place tradition, to avoid loosing the seed phrase in the case of fire outbreak, i would suggest we find somewhere around our homes, dig it and bury the seed phrase there after having packaged it in a way it wont be destroyed by heat, cold, rain and earthworms.
This does not stop us from writing one and keeping it safe inside our homes, the one buried outside should act as an emergency recovery if for any reason, the one inside our home is not accessible to us..
Though the above, is for those who can not avoid a safe box.
