First of all I use this medium to acknowledge the organisers and programmers of this forum/site, indeed they have done immensely great job by uniting individuals of various countries in the globe to share their respective ideas.
"The organisers and programmers of this forum/site" is Satoshi, who, as I assume you know, is known for much more than just that.
You could express your gratitude to the administration for their support of this forum; without them, bitcointalk would not exist.
I have been reading a lot of post and replies where people debates on the safest way to store up Bitcoin seed phrase, some folks said writing it on paper and storing the paper in a secret places is the safest means there by preventing Cyber attacks while other folks said storing the seed phrase in a special hard ware device is the best way.
It is best to combine these 2 methods: offline storage of the seed phrase on a physical storage medium (paper, cardboard, metal - any material on which information can be stored for a long time) + use of a hardware wallet.
I was thinking about all those ideas and I came up with a thought that leads to questions.
1. Is it good to give our seed phrase or wallet password to our next of kin while we are alive since death is inevitable?
I'm sorry to disappoint you, but death is inevitable.

You should only transfer the seed phrase to people you're willing to give your savings in bitcoin to. Whether it's in your lifetime or not, it will happen anyway, right?
I think you could do it this way: split bitcoins (diversification) and have several seed phrases. Keep seed phrase №1 \ №2 for yourself, and transfer seed phrase №3 to a relative.
2. If the answer to the first question is Yes, what then happens to us if the next of kin defraud us of our hard earn wealth while we're alive?
If they try to deceive you, you'll keep some of your savings, which you might still need.
Therefore, seed phrase №3 should contain a small amount of bitcoins (as a test) to verify the trustworthiness of your relatives to whom you would like to bequeath a bitcoin inheritance. Perhaps this will help you change your mind and "bequeath" bitcoins to other people.
