we can’t still give up, we have to make a step to teach them first by introduce them to Bitcoin when they are growing older so as to build the love for privacy and decentralized systems in them; when you noticed they are good, you then make your decision by giving one of them some hint on how they can have access to your Bitcoin when you are no more; or you can also get a wallet for them and send some money in their wallets; keep the seed phrase in the same place you saved your seed and indicate theirs so that there will be no drama after you left.
Different people will have different ideas about how they can give access to their heirs once they are gone, and everyone should know what can work best for them. I always think about this topic when I'm alone and doing nothing, we get a lot of thoughts about the future, what we are going to do, what can give our loved ones a better future and all those things, and if you are someone who has something that the heirs can inherit when you pass away, then you will surely also think about how you should do it. If it has to be distributed among multiple heirs, how that can be done successfully because we often see people fighting over such things, people even kill each other for inheritance.
So, in my opinion, what I believe can be the best practice is to have a safe in your house. It should be a safe that only you and your direct family knows about, and it should be at a place where it can't be found easily unless someone already knows about it so that in cases of robberies and thieves breaking into the house, they shouldn't be able to find it, but you should tell your family about it. The safe should have Two-Step verification where one step is to use the key, and then it should ask for a pin or a password. The seed phrase should be kept inside the safe, key should be with you, and then you should write the pin or the password in the will and also mention the percentages each person should get.
