Bitcoin also fails to meet the criteria of a currency. Its the price movements are too volatile to be a unit of account. The transaction capacity of the Blockchain is too limited for it to be a medium of exchange. Nor does it appear to be a good store of value.
Since it produces no income, has limited scarcity value, and few people are willing to use Bitcoin as currency, it is even possible that Bitcoin has no intrinsic value.
