The problem of seeds is obviously crucial. Can we imagine being the one and only person who knows what to do with these 12/24 words? How to keep them safe, but also how to pass them on to heirs or friends (so that they know what to do with them?). Informing others while preserving your own security can be a real challenge in some countries.
And then there's betrayal, divorce etc...
What are the solutions?
I once thought about how I would pass on my seed phrase to my family if something undesirable happened to me, such as going into a coma or even dying. So I wrote down my seed phrase in a safe place and wrote some notes on the paper, namely by adding "For my family who find this paper, this is a seed phrase that has Bitcoin assets in it, please ask some of my friends......... to access it", and of course I mentioned some friends who understand Crypto, especially Bitcoin on the note. For me that was the best solution, and maybe there was a betrayal for that, but I can only hope that it was truly inherited fairly through the note. But I think it will be different when my age lasts a long time, and when my old age finally comes, maybe I will truly inherit it fairly for my family's inheritance.
