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.
Our Bitcoin accumulation getting lost when we die of sudden; is it what will raise concerns? Many people lose their properties that weigh billions of dollars, and life still goes on without holding on a bit.
If peradventure we didn't tell anyone about our Bitcoin accumulation before we die, life goes on, and our families will survive on their own without our wealth. We were born into the earth empty-handed, and we are leaving the earth with nothing. I don't bother myself with the wealth to accumulate on earth because they will all be vanity when we are no more. The living will squander the wealth we suffer to build over the years for our good. Why are we bothered about them when they can survive without our wealth(us) existing.
