Stablecoins: how do they work? Best Stablecoin Interest Rates

Stablecoins are a category of cryptocurrency. They have become very popular in recent years, due to some characteristics that distinguish them from other crypto coins and tokens.

Stablecoins, as the name suggests, are known for their price stability, unlike volatile crypto assets. Thus, many investors in the cryptocurrency market often convert assets like Bitcoin and Ethereum into these stablecoins, especially when a downtrend in the market is expected.

In other cases, investors convert crypto assets into stablecoins to mitigate losses. Additionally, cryptocurrency traders often trade against a stable asset, so that when their target price is reached on their preferred cryptocurrency, the capital and profits are converted into one of many stable coins.

How do stablecoins work?

Stablecoins operate on an interesting model. Sometimes they are considered the “fiat” of the cryptocurrency market due to their relationship to traditional fiat currencies. Stablecoins are backed by reserve assets ranging from US dollars to gold and cryptocurrencies.

They maintain a 1:1 parity with these reserve assets to ensure price stability. USDT, the most popular stablecoin, is backed by the US dollar; for every 1 USDT in circulation, there is the equivalent of $1 in reserve. Ideally, investors can exchange their USDT for fiat dollars. One of the popular stablecoins is also the Australian dollar token (AUDT), which is pegged to the Australian dollar and backed by an Australian bank. With the Crypto Exchange TimeX service, you can buy any amount of AUDT. Which makes it more user-friendly for Australian users and enables the efficient and secure transfer of funds to and from the blockchain ecosystem. Here you can see the current Bitcoin AUD chart.

Stablecoins provide a safety net for crypto investors and traders that other crypto assets do not. Investors prefer to earn returns or interest on their stablecoin assets by depositing them in a decentralized finance (DeFi) protocol. In contrast, while investors can earn returns on other cryptocurrencies, they generally need to worry about price volatility. Price volatility causes cryptocurrencies other than stablecoins to lose value.

Types of stablecoins

Not all stablecoins are the same. There are different types of stablecoins. A common feature of all stablecoins is that they are backed by a reserve asset. However, these reserve assets may vary. So, we have stablecoins backed by the US dollar while some are backed by a combination of the fiat dollar and other cryptocurrencies. Types of stablecoins include;

  • Stablecoins backed by Fiat

Fiat-backed stablecoins are the most widely used stablecoins. These include Tether (USDT), USD Coin (USDC), Binance USD (BUSD). This category of stablecoins has its reserve assets in the form of fiat currencies such as US Dollar, Euro, and Pound. Moreover, they are controlled and issued by centralized entities.

  • Crypto-backed stablecoins

Crypto-based stablecoins are backed by other cryptocurrencies. A perfect example is DAI, which is backed and over-collateralized with Ethereum. DAI is over-collateralized because ETH is another volatile crypto asset.

  • Commodity-backed stablecoins

Gold is a commodity and reserve asset for stablecoins such as PaxosGold and DigixGold. Both stablecoins can be exchanged for gold.

  • Algorithmic stablecoins

Algorithmic stablecoins maintain price stability by using an algorithm that allows more coins to be issued when prices rise. However, when prices fall, coins are bought from the market to keep prices high. Examples include the defunct Terra USD (UST), Abracadabra MIM and Near USD (USN). They are also called algo-stables.
