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?
Seed phrase is an important key that can contain all your life savings. Considering its importance, it definitely deserves maximum security. Otherwise you can lose everything in an instant. It can be write on a piece of paper but if it is keep on a digital platform it will be safe to protect it from fire or any other form of damage. Remembering the seed phrase is risky and can be all over if you make a mistake. So I think it's safe to write it down. A user can keep it where it is convenient considering its maximum security. However, if the password is stored in a safe place, he will be able to easily remember the short password of that platform for login where the seed phrase is usually longer that will be comparatively difficult to remember.
