You might be hearing the word stablecoins a lot, yet it’s not easy to understand how they differ from bitcoin and other cryptocurrencies. The original purpose of stablecoins was to use them as a balancing asset to volatile cryptocurrencies, and thus most stablecoins are designed to minimize their volatility. The majority of the early stablecoins derive their value from a national currency, often the U.S. dollar (USD). The contemporary market has been evolving in the direction of commodity-backed stablecoins and complicated fractional-reserve stablecoins.

Stablecoin Market Abstract

The growth of the stablecoin market has been closely aligned with growing cryptocurrency and blockchain markets. In early 2021, the total market capitalization of stablecoins ascended to 38,46 U.S. dollars and a total 24h daily volume into $90,9 billion.

Tether (USDT) is arguably the most well-known stablecoin, yet it’s also one of the most controversial ones. Tether’s history dates back to 2014. Since then, the industry has scaled up significantly in a more diversified direction. The stablecoin market can be segmented into currency-backed stablecoins, commodity-backed stablecoins, and algorithmic stablecoins. Let’s explore these segments in detail.

Currency-Backed Stablecoins

Stablecoins backed by national currencies, or fiat currencies, form the biggest stablecoin segment by market capitalization. The value of these stablecoins is backed by a third-party financial entity, and the issuer forms an essential relationship with the custodian of the backed asset. Stablecoins backed by national currencies can be traded on exchanges and can optionally be redeemed from the issuer.

Tether (USDT)

Tether (USDT) is probably the most well-known stablecoin, and the U.S. dollar reserves back it. Recently Tether announced its stablecoin to be backed by “a reserve of U.S. dollars and other assets, including traditional currency and cash equivalents and other assets and receivables from loans.” Tether has faced accusations related to alleged insufficient reserves, and Tether’s parent company iFinex is currently under scrutiny by U.S. authorities.

Nevertheless, Tether has continued to grow exponentially and is currently worth above 26,3 billion dollars. Tether contemporarily uses multiple blockchains, including original Omni, Ethereum (ETH), and Tron (TRX). Ethereum-based Tether holds most of the value in market capitalization. However, Tron-based USDT bypassed Ethereum in terms of daily active addresses during early 2021.

Despite Tether’s regulatory challenges, many industry specialists forecast a good future for USDT. Nic Carter recently commented on the alleged link between Tether issuance and bitcoin’s price. He sees stablecoins as an inherent part of the ecosystem and denies the relation between Tether’s circulating supply and bitcoin’s price performance.

“Tether and other stablecoins are just a proxy for the balance sheets of trading firms and crypto-native institutions. Crypto-native firms grow as the underlying assets grow.” – Nic Carter

USD Coin (USDC)

USD Coin (USDC) fits into the same currency-backed category with Tether (USDT), and USDC is contemporarily the second-largest stablecoin in the market, using market capitalization as a metric.

USD Coin’s role is closely aligned with Tether. However, it has found its economic moat as the more regulatorily compliant stablecoin. USDC’s current market cap is €5,8 billion, around 22% of Tether’s market cap. Should the regulatory concerns around Tether escalate, USD Coin might see incremental growth at Tether’s expense.

Commodity-Backed Stablecoins

Stablecoins backed by commodities, like gold, have seen escalating growth during recent years. Physical gold shares many features with bitcoin, both were mainly designed to be scarce, and both are a good hedge against inflation. The deflationary characteristic of gold ensures its long-term value potential.

The gold-backed stablecoin market is dominated by two rival stablecoins: PAX Gold (PAXG) and Tether Gold (XAUT). Both stablecoins allow for exposure to gold markets without using an ETF, futures contract, or other derivative product. Both issuers store their gold reserves in a secure third-party location, and clients’ assets can be redeemed easily. PAX Gold bypassed Tether Gold in terms of market capitalization; PAXG’s market cap is currently $113,18 million and USDT’s $88,52 million.

Gold-backed stablecoins contain significant growth potential as the demand for the asset is perpetually increasing. Tokenizing physical gold into digital assets by blockchain technology seems to be a perfect match. Gold-backed digital assets can be purchased via Coinmotion private banking service.

Algorithmic Stablecoins

Algorithmic stablecoins offer another angle to solving stablecoin stability. Stablecoins like Frax balance the stablecoin price by counter-cyclical price adjustments: Expanding the supply reduces the price and reducing the supply increases the price, vice versa.

Frax is the first fractional-algorithmic stablecoin protocol currently implemented on Ethereum (ETH) ecosystem. Frax plans to be a highly scalable, decentralized, algorithmic money in place of fixed-supply digital assets like bitcoin.

Frax consists of three tokens: FRAX (stablecoin), Frax Shares (governance and value-accrual token), and Frax Bonds (debt financing token). Frax’s founder Sam Kazemian stated the project plans to be “the bitcoin of algo stablecoins,” and Frax will provide liquidity for decentralized finance as an algorithmically stabilized and unbacked asset.
