Recently, I've been watching the TV series YellowStone, which tells the story of an old rancher who will stop at nothing to keep the ranch for the next generation. The matter of leaving it for the next generation still relies on the support of the government/society. Passing down private keys to the next generation? If they don't know how to operate it, take a photo and upload it to the cloud, or lose the private key, there are too many unpredictable factors. Passphrase? The old man never mentioned it. Multi-signature? Custody? Each has its own unreliability. Multi-signature, if the family members are not industry insiders, don't expect them to learn it. Moreover, this solution is not that robust, especially if the family travels together, it is not physically dispersed. But there is also a fear of societal radicalization. If someone flips the table, don't expect to leave anything behind. Perhaps the approach of the Shaw family is more prudent. The business itself spans multiple locations in Hong Kong and Southeast Asia, with businesses and assets everywhere; it’s unlikely that all N countries would flip the table. The means of passing down wealth are already in place, but starting tomorrow, we still need to work hard to create wealth.

If the private key holds 5 to 10 million, what should I do if something suddenly happens and I can't pass it on to my family? Buy a life insurance policy with a coverage amount of 5 to 10 million, and inform my family about the policy details and contact person. This applies not only to the private key but also to small amounts of money scattered across various banks in different countries, which are practically impossible to recover. The only way to compensate for this is through life insurance, which can provide a one-stop solution. Anything recovered beyond that is pure profit.

The small amount of money in a (foreign) bank, if the family is unaware of its existence, will not automatically go to the family if the person is gone; it becomes dormant customer assets of the bank, roughly equivalent to excess reserves.
