I went to market with my wife to buy things for our new born baby, after my wife selected baby things that Worth thousands and I paid with my btc,the transaction was very easy and faster. When we returned home ,she asked if you die can I achieved your btc or continued with your account? Because it's very easy and faster in trading and transaction.
Of course yes she can acquire your bitcoin especially your assets as long as she knows the seed phrases or the private keys of your wallets so that when you die she can easily access the wallet that you are using. Another thing is that when you buy a ledger and share with your husband then probably you will be able to have access also on his wallet. This is a good thing to do when you have a family because whenever you died there is always a person who will be able to acquire the assets that you've left.
