"Bitcoin can’t be a store of value because it has no intrinsic value. It can’t be a unit of account because it is too volatile. It can’t be a medium of exchange

"Bitcoin can’t be a store of value because it has no intrinsic value. It can’t be a unit of account because it is too volatile. It can’t be a medium of exchange because it is not widely used to price goods and services. These are the three properties of money. Therefore, Bitcoin can’t be money. But Bitcoin has no other basis for being valued, therefore it is valueless. QED." The last sentence introduces an extraneous assertion that is incorrect: "But Bitcoin has no other basis for being valued...". Not everything that has value is money. A painting isn't money: it has value because people want it and want to pay for it. Bitcoin isn't money, but it has value as long as people want to pay for it.
