I read the whole post.
And exactly that is my point of view there should be anyone whome your coins to be passed.
If there is Bitcoin so h/s must has the knowledge about Bitcoin, to whome these coins will be given. The owner should focus on the education of heir. Should be preplanned that how h/s can access the private keys. If h/s has the knowledge so h/s will focus on holding.
Educating them doesn't magically input experience on them
If they are not already into the system
There's a high likelihood that they would sell it
Immediately the owner dies
You said continue holding, for how long?
Some people are holding for themselves but can choose to prepare for eventualities and give access to a family member or friend
It all boils down to the level of trust and love.
To be sincere if am passing my holding
I wouldn't expect them to actively hold
But use in the case of emergencies or a fighting chance for a better future.
At least even while dead
I made an impact to their success.
As long as the money wasn't squandered recklessly
I see no issues with them not holding.
