I have a new perspective towards what it means to keep things private. I am thinking that keeping things private does not always mean keeping things to yourself. Before you criticize, I know that to have someone as trusted as that is rare and almost impossible, but they still exist, and sometimes you can find that person in your spouse. If you can share important details like passwords of bank account or safe, or grant them access to important documents, should we not also be able to trust these people with access to our bitcoin wallet?
I think we can trust whomever we choose to trust, based on how we have accessed their behavior pattern.
Also, not every trusted person can be trusted with everything, because some may become something else if they come in touch with the money bag but may be well okay with any other thing entrusted to them.
In the case of a spouse, it's good trust exists, but as a man, you should know that when it comes to your finance, your spouse shouldn't be trusted with all your sources of income, at least some assets and investments should be private and a secret until maturity or should there be a case for its need mostly in a case of divorce wherein all the mans money and asset will be divided in two .
