Bitcoin vs stablecoins, what is the difference?

The difference between bitcoin and a stablecoin comes down to design. Bitcoin is a cryptocurrency with no company behind it and a fixed supply, so its price moves freely. A stablecoin is a token that a company issues and backs with reserves so it stays close to one unit of a currency, usually the US dollar.

What is the difference between bitcoin and a stablecoin?

Supply works in opposite ways. The Bitcoin.org FAQ says only 21 million bitcoins will ever be created, released on a fixed schedule that halves over time. A stablecoin's supply grows and shrinks with demand, because the issuer creates tokens when customers deposit dollars and destroys them when customers redeem.

Control is also different. The Bitcoin white paper describes a payment system that works without a trusted third party, using proof of work and a peer-to-peer network to stop double spending. No one owns the Bitcoin network, and changes only happen if users, miners and node operators adopt them. A stablecoin depends on its issuer to hold reserves, honor redemptions and run its smart contracts.

Backing differs too. The Bitcoin.org FAQ says bitcoin is not backed by physical assets or a central authority, and its value depends on people being willing to accept it. A dollar stablecoin is backed by assets the issuer holds, and its value depends on those reserves being real and reachable.

Is bitcoin a stablecoin?

No. Bitcoin's price is set by supply and demand, and the Bitcoin.org FAQ notes that it remains volatile. A stablecoin aims for a steady price. The tradeoff is that holding a stablecoin means trusting its issuer, while holding bitcoin in your own wallet does not rely on any company.

How are bitcoin and stablecoins regulated?

In the US, the GENIUS Act, signed on July 18, 2025, created a federal framework for payment stablecoins. Covington's summary says only approved issuers may issue them, each token must be backed one-to-one by reserves such as dollars or Treasury bills, issuers must publish redemption policies and certify reserves monthly, and large issuers face annual audits. Payment stablecoins from permitted issuers are also excluded from the definitions of a security and a commodity. Our GENIUS Act guide covers the details.

Bitcoin has no issuer, so there is no one to license in the same way.

Will stablecoins replace bitcoin?

They are built for different jobs, so they do not compete head to head. Stablecoins are mainly used as digital dollars for payments, trading and moving money between platforms, where a stable price is the point. Bitcoin is a scarce asset that runs without an issuer, which is why some people treat it as a long-term store of value despite its volatility.

The two can sit side by side, for example stablecoins used for spending or trading and bitcoin held as a separate asset.
