Bitcoin is a very valuable crypto asset, everyone should be worried about losing this asset. Bitcoin can be inherited as long as the person receiving this asset understands about Cryptocurrency. If you need an application about legacy programs of course this app should be safe as they will store private keys. From now on we may have to provide information about our assets against wives and children (children who grow and understand the online world).
I personally have taught my wife to learn digital currency trading. So when I am not automatically there is my wife who will later inherit the crypto-currency assets.
