It is a digital currency, you can't touch it, you can't see it.
If you can't use it doesn't mean that other people can't. Most of us use it regularly to buy goods and pay other Bitcoiners.
You don't have to be the item that holds value to be usable.
A thing that makes this item safe is usable.
A thing that moves it around is usable.
A thing that stores it is usable.
Even if the sole use of Bitcoin was to be an emergency store of value for when your country goes bankrupt or gets nuked by neighbors it would still be one. Only you don't want to acknowledge it.
These generic statements of yours cannot change the fact I stated in the op: in the bitcoin circulation chain no end consumer exists that can use bitcoin for consumption or for satisfying his human needs, like food is used by hungry people or dollar by borrowers. For that reason, profit or benefit for chain members can come from new investors only, which is a textbook definition of Ponzi or other type of pyramid scheme. So bitcoin can be called money, value, digital gold, safe, usable, new internet, emergency store or ... whatever, but this is just semantics and its Ponzi nature or ultimate fate won't change because of that.
