In simple terms, stablecoins are digital currencies tied to the value of
fiat funds or any other asset.
Tether (USDT)
The advantage is its own platform for working with fiat funds using the blockchain system. Before the appearance of new coins in 2018, it occupied a leading position among the best stablecoins. The cost of a coin is equal to $1, but sometimes it can vary from 91 cents to above a dollar. The guarantor is the Bank of Hong Kong, whose accounts hold user funds. The blockchain system is used in its operation. The management of output, liquidation, and demand tracking is implemented through the Omni Layer protocol. The company regularly provides reports on the status of accounts. The data is compared with blockchain registries.USD Coin (USDC)
Recently, the currency has appeared on the market due to the joint work of two exchanges.It is based on the CENTRE technology, which is built on the Ethereum blockchain.
The creators cooperate with financial organizations that regularly provide reports on the state of the monetary fund. The creators themselves provide all control over the functioning of the system. Users can register on the official website. The identification procedure is simple and quick. However, the ability to return funds is available only for customers of U.S. banks.True USD (TUSD)
coins appeared on the market in 2018. The stablecoin is provided by the dollar in a ratio of 1:1. The creators characterize the cryptocurrency as the most manageable and independent. Collateral funds are stored in third-party storage. All the money goes to the trust institution, and the developers do not have access to it and do not participate in the transfer. The creators cooperate with several financial companies at once. The release takes place using smart contracts at the request of customers.Digix Gold (DGX)
is a stablecoin backed by physical gold. Individual tokens are responsible for creating a DGX token to preserve the identity of the gold bullion linked to it. The Proof of Asset (POA) technology is used for security. It is managed through a smart contract involved in the creation of the DGX token. Any DGX owner can cash out their DGX in real physical gold bars according to the specified value. Almost 200 million DGX tokens are currently available, and the stablecoin plans to expand beyond a single repository in Singapore.Photo by on Unsplash
Usually, they are "tied" to the price of an asset, for example, to a 1:1 fiat currency. In most cases, this is the U.S. dollar, where 1 unit of the coin is equal to $1. However, there are stablecoins tied to other currencies, such as the euro, yuan, or even to precious metals or other goods.The of a coin tied to a fiat currency is that it will retain its value regardless of the situation in the crypto market. The mechanism of operation is the same as that of paper money.
At the same time, fiduciary (fiat) money functions based on laws that
oblige people to accept them according to face value. The state is the
guarantor and sets the price of paper money, regardless of how much money was spent on their production.
Stablecoins differ from cryptocurrencies in that they have a low volatility
index.
Advantages of Stablecoins:
Stablecoins differ from cryptocurrencies because they are not so much
exposed to the schemes of a “pump” (artificial speculative appreciation of a
digital asset’s price) and “dump” (the selling off of the inflated asset,
lowering the price). As a result, stablecoins are resistant to financial
collapses.
The classification of stable cryptocurrencies is based on the method of
their provision. The stability of the virtual currency price can be guaranteed
in these ways:
Below is the stablecoin list with a description of the features of each
type:
Unsecured Stablecoins
This type is decentralized, but its rate is more stable. This is achieved
thanks to the “seigniorage” method (seigniorage is an old word meaning the right to make a profit from minting metal coins for the state).
The issue of new coins directly depends on the demand for stablecoins.

The main difficulty lies in the process of adjusting the stability of the
exchange rate. The issuer uses the method of smart contracts, which affects the volume of issuance of stablecoins.
Backed by Another Digital Currency
This type of stablecoin retains its decentralization. Stability is ensured
by the fact that it is necessary to spend much more than other cryptocurrencies on the issue of each coin.
Secured by Fiduciary Money
The principle of working with such a cryptocurrency is that the user
replenishes the electronic account with ordinary money. Then, they are
converted into digital currency at the same price.
The difficulty lies in the fact that a third party is responsible for the
safety of the system. To prove its ability to act as a guarantor, audits of
accounts are constantly carried out.
