this same question is included in the pow which was provided by you. And Of course in my own opinion I will say that the BTC and or asset in my possession will be transferred to my hairs or children/grandchildren. For inheritance purpose and it could be that I will not transferred all to them by some and also transferred some to the ophanage home.

Apart from BTC the only other coin I think will be the subsidiariy of bitcoin is the Ethereum but I mainly think of BTC as the only coin that can maintain the standard of 20-100years, because it's the first coin to ever existed with great potential and good store of value.
