So if you've been with someone for years or even decades, you've got kids or even grand-kids together, you still think you should hide your bitcoin activities from them? Maybe a new partner or spouse you've been with for only a few months, sure, but at some point when you build a life with someone, you share your finances with them.

I'm one of the strongest privacy advocates on this forum, but at some point, this just becomes common sense to let your spouse know. Why would I want to risk me suffering from memory loss or dying and none of my family being able to access or benefit from my bitcoin? My wife is fully aware of all my wallets, all my back ups, all my security, etc. Why would I want to keep that from her? If you are having so many doubts about your relationship that you think you need to keep a large part of your finances completely hidden, then you should have signed a prenup.
