If you have a guy of your own or you have a girlfriend, he will be able to use your bitcoin if you give him all the bitcoin devices you left in the moment before he dies. Also, if you leave all your documents in a notebook, then of course someone can recover them.
So what I have realized here was it is bwtter that you have someone that you are trusted like friends and most especially your family memeber that could understand more about bitcoin and cryptocurrency and shared your passwords, the keys or private accounts so even if some unexpected accidents happen the bitcoin that you have earned will be left on someone you loved.
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.
I love the thought that we can now enjoy the service of paying your groceries over the counter and without the worries of needing to convert your bitcoin into fiat right.
