have some faith on your wife and tell her everything about your bitcoins...
it's difficult to trust people, in today's world women and men have become interested, if one of the partners is very rich, you risk being murdered by your own wife or your own husband, in my country is full of cases of this kind.
is difficult and very complicated, money changes people, most people do anything for money, even if it is your wife, son, mother or father or any member of your family money can corrupt them, if you have many bitcoin and you are very sick I would advise to withdraw everything to your bank and if you died the situation would be different... banks are explorers but in certain situations they are very useful
Wow! I haven't seen that coming. Wife will murder the husband over Bitcoin, well that's possible if the couple were not in good terms but they do know each other's keys to access digital assets.
Common sense should be used this time, if you don't trust your wife then entrust it with your siblings or your best friend whom you have known for ages
