You can't hold it forever. It becomes like hoarding without application. You seem to have something, but it doesn’t affect your life in any way. I think the point of holding is to make a profit. And if the profit is unrealized, then it is not a profit at all. Therefore, the holder must have a goal in which he cashes out at least part of his position.
Its not holding anymore if they don't have plans and just think about holding it without proper timeline since maybe as you said it will became hording. But he should set a plan regarding on his holdings since if he just do that for the sake of he has something to tell that he's a bitcoin holder then maybe there might be a chance that he could lose his bitcoin especially if there's sudden unfortunate changes will occur. Proper planning is important so they can set some goals on what year they should sell since its important to secure our profit if our targets has been meet.
Also its different story if there's an emergency situation happen and your emergency funds is not enough to cover up your needs then its good to sell your holdings so that you can get a solution on your problem then I think this is also a somehow good scenario to sell but if there's nothing like this happen and everything is in normal situation then continue to hold for better future.
