If you are a single bitcoin investor, would you rather teach a trusted family member about Bitcoin than involve your personal lawyer. I ask this because I grew to understand that lawyers are good at handling confidential issues like Wills.
My answer would be "trust no one". Some lawyers are legit, while others cannot be trusted. The same applies to family members.
What do you mean by "teach"? Do you want to teach a family member(or a lawyer) about crypto and how to use it, or you plan to give them your private keys? Those are two completely different things. You should elaborate more on your question.
It doesn't make any sense to "teach" your lawyer about crypto. Do you want your lawyer to handle your will after you die, or you want your lawyer to manage your crypto investments(even though a lawyer and a broker/trader have nothing in common)?
