"STORE OF VALUE" IS A SYMPTOM OF USEFULNESS!
It's an usefulness in itself. (and why the yelling? getting stressed so easily?)
If I make a sword out of bird shit and just build one -- and let's say nobody else can build it, does it necessarily have value because it's scarce?
If you convince other people it's a good store of value, it might. That's not easy at all, though.
By the way, if at least you value your shit sword, then it already has value - to you, at least.
If people quit using Bitcoins as a medium of exchange to purchase goods, other mediums of exchange, or services, then it would be worthless. It doesn't matter if everyone still has the same number of coins, because you can't buy anything with them.
If you can still trade them for currency at least, it can be used as a store of value.
It's true that if there really isn't any function at all to something, then it will not have value.
The only thing I'm trying to say is that this claim that bitcoin needs to be used in commerce (trading it for goods and services) to have value is false. It doesn't need to, although it helps a lot to have such utility.
Why are Bitcoins worth $5 now, but $.00001 a couple years ago?
Because prices change?
Bitcoins are multitudes less scarce than then, and it has the same ability to store values as it did when it was created (okay - arguably less because the network was less secured).
Prices are a function of scarcity and demand
. A particular usefulness of a scarce resource won't necessarily translate into demand until this usefulness is perceived and desired by people.
Bitcoin is a fantastic medium of exchange. It's irreversible, extremely easy to send to someone else, doesn't require a clunky centralized payment processing systems to quickly use online or send internationally, and is pseudonymous. Those are all great, but that doesn't cause Bitcoins to be worth anything -- what causes them to be worth something is because originally, a few people saw potential in it.
Bitcoin doesn't inherently have value - people give it value
That's true for absolutely everything which has value. There's no such a thing as "inherent value".
