I hope most of the post we read here were not just aimed at deceit. Like how do we still think it's arguable if a person decides to sell his accumulation. 10 to 20 years is quite a big length of time. So it's already above a decade and it's a whole lot of patient driven holding. A trader spares no bitcoin if there's any small market rise. Someone who has held his accumulation for ten years can sell a part even though it doesn't mean he can't hold any longer.
We accumulate to sell later. Anyone who accumulates indefinitely may loose all investments if he eventually dies or looses his log in details. While accumulating, don't forget that life is not indefinite.
You do not have to either continue to accumulate or to sell all of your bitcoin in order to find some kind of a balance.
Many times folks reach a high enough accumulation of an asset that they can sell small amounts at various points in time, so maybe after 10 or 20 years a person's bitcoin holdings might be 5-10x in profits.. so they are not very worried about selling some of it, but they still don't have to sell all of it in order to get benefits from having had accumulated it.
There are some folks that don't sell their most pristine of assets, so they might use their most pristine of assets as collateral.
There is no need to think about bitcoin as all or nothing or as if it were a trade, rather than an investment that is held onto since bitcoin still might be the best of assets 20 years from now, so why would you want to sell your best investments, unless that is the ONLY thing that you have left.. .. and presumably people don't have 100% of their net worth ONLY in bitcoin, even 20 years from now.
