Is cryptocurrency real money?

Cryptocurrency does some of the jobs of money, but it does not do all of them well, and most governments do not treat it as money in law. Tax authorities in the United States and the United Kingdom classify it as property or an asset. Whether it counts as "real money" depends on whether the question is about economics or about law.

What makes something money?

Economists usually say money does three jobs.

• Medium of exchange. People accept it in payment. Some merchants take crypto, but few customers pay with it.
• Unit of account. Prices are quoted in it. Almost nothing is priced in bitcoin. Even crypto itself is quoted in dollars.
• Store of value. It holds its purchasing power over time. Bitcoin's supporters say it has done so over long periods. Critics answer that an asset that can lose much of its value in weeks is a poor place for savings.

A stablecoin, a token designed to track a currency such as the dollar, comes closer on the first and third tests. It does so by borrowing the dollar's stability, not by replacing it.

Is cryptocurrency legal tender?

Legal tender is money that the law says must be accepted in settlement of a debt. Countries normally give that status only to their own national currency.

El Salvador was the first country to make bitcoin legal tender, in September 2021. It changed course in January 2025. Under a loan program with the International Monetary Fund, the country amended its law so that businesses may choose whether to accept bitcoin, and taxes are paid only in US dollars.

Not being legal tender does not make crypto unlawful. Owning and trading it is permitted in most countries, as the guide to whether cryptocurrency is legal explains.

How do governments classify it?

Mostly as property. The IRS says digital assets are treated as property for federal tax purposes, a position it first set out in 2014 and still held as of October 2026. Selling or spending crypto can therefore produce a taxable gain or loss, as covered in how crypto is taxed in the United States.

The UK tax authority, HMRC, states in its guidance that it does not regard cryptoassets as currency or money. See how crypto is taxed in the UK.

Rules differ by country and state, and they change. Check the official source or a qualified professional for your own situation.

So is it real?

It is real in the sense that it can be owned, sold for dollars and stolen. Courts and tax agencies treat it as property with value. It is not money in the full sense that dollars, euros or pounds are.

A central bank digital currency, or CBDC, is a separate idea. It is a digital form of a national currency issued by a central bank, and it would be money in the legal sense.
