Stablecoin

A stablecoin is a cryptocurrency designed to maintain a stable value, typically by being pegged 1:1 to the U.S. dollar (or another stable asset like gold). USDT (Tether), USDC (USD Coin), and DAI are the largest examples. Stablecoins combine the censorship-resistance and speed of cryptocurrency with the price stability of fiat currency — solving one of the main practical objections to using volatile assets like Bitcoin for everyday commerce.

What it means

Bitcoin's volatility makes it challenging for commerce: the price can swing 10% in a day. For a merchant, this creates currency risk that doesn't exist with dollar payments. Stablecoins let businesses accept and hold digital payments denominated in dollars, without the volatility and without the payment processor middleman who could cut off service.

Stablecoins have their own risk profile: centralized stablecoins like USDC can be frozen (Circle, which issues USDC, has frozen wallet addresses at government request). Decentralized algorithmic stablecoins carry smart contract and peg-stability risk, as the collapse of TerraUSD in 2022 demonstrated. Understanding the backing and governance of a stablecoin matters.

How it works on Gab

For Gab Marketplace sellers who accept cryptocurrency from buyers, stablecoins offer a practical option: a dollar-denominated payment without routing through a payment processor that can be politically deplatformed. These transactions happen directly between buyer and seller — Gab does not process them.
