As your investments begin to mature into a considerable amount, while you consider the security and safety of it, it is also important that you consider the situation where you die suddenly and your Bitcoin gets lost; no investor would want that except they have no family and friends worthy enough for it.
This is very sad to read and it remind me again about Diego Jota who passed away this week too at a younger age. No one can tell when death will visit them and this sometime leave us in confusion as to whether to disclose our assets to a trusted person or not. What if you disclosed it earlier and you're yet to die but later get betrayed?
Ideally, one is suppose to enjoy the fruit of their investment before they die because there's no point making investment without having a test of your several years of patience unless untimely death happens. I will suggest to keep your keys in a place reachable after your death to avoid complete loss of asset. If one can not enjoy it due to untimely death, at least the families should be able to enjoy it.
