Currency has no requirement to be a store-of-value.
but it
can be one. gold/silver/metal coins are an example of stores of value that also function as currency.
A store-of-value can only be achieved by an asset that has an underlying intrinsic value like bitcoin.
i would argue that bitcoin has no underlying intrinsic value. you can't consume it, you can't turn it into something useful, it has no industrial/medical use.
bitcoin only has value because people use it. if no one used it, bitcoins would be worthless, so the value must not be intrinsic.
