What is a stablecoin?

Simply put, stablecoins are a special cryptocurrency, and their goal is to "stability".

The prices of cryptocurrencies such as Bitcoin and Ethereum that we are familiar with are volatile, and may rise or fall by dozens of percentage points in a day, which makes it difficult for them to be used as payment or value storage tools in daily life. The birth of stablecoins is to solve this problem.

Its value is usually "pegged" to some stable asset, the most common being the US dollar. In theory, the value of a stablecoin is about $1. You can understand it as the "digital dollar" or "electronic dollar" in the blockchain world.

The main types of stablecoins

1. Fiat currency collateralized stablecoin: This is the most mainstream one. For every stablecoin issued by the issuer, he deposits $1 in his bank account as reserve. The well-known USDT (Tether) and USDC (USD Coin) belong to this category. Because of the endorsement of real dollar assets, their value is relatively stable.

2. Cryptocurrency Collateral Stable Coins: This stablecoin is issued by other cryptocurrencies (such as Ethereum) as collateral. To cope with the price fluctuations of collateral, over-collateralization is usually required (such as collateralizing Ethereum worth $200 to generate a $100 stablecoin). DAI is a typical example.

3. Algorithmic Stable Coin: It does not rely on any collateral, but uses a set of intelligent algorithms to automatically adjust the supply in the market to maintain its price stability. This type of design is complex and has also experienced the risk of serious price decoupling.

Why are the hot searches in TikTok discussing stablecoins?

The main reasons why stablecoins suddenly sparked heated discussions on popular platforms such as Douyin:

Safe haven: When the cryptocurrency market falls overall, investors will sell Bitcoin, Ethereum, etc. in their hands with price fluctuations and exchange them for stablecoins to lock in profits or avoid further losses. When the market fluctuates violently, the trading volume and discussion of stablecoins will increase sharply, playing a "safe haven".

The "bridge" to enter the crypto world: For most novices, the first step to buying other cryptocurrencies is often to first use fiat currency to buy stablecoins, and then use stablecoins to trade Bitcoin, etc. It plays the role of a key "bridge" or "transfer station" connecting the real world fiat currency and the crypto world.

Tools to earn high returns: In the field of decentralized finance (DeFi), users can deposit their stablecoins into various protocols for "financial management" to earn interest. The annualized rate of return of this kind of financial management is sometimes much higher than that of traditional bank deposits, attracting the attention of a large number of users seeking stable returns.

Cross-border payments and value transfer: Compared with traditional international remittances, cross-border transfers are fast, low handling fees, and are not subject to holiday restrictions. This makes it increasingly popular in international trade, personal remittance and other fields, and discussions on related application scenarios have also increased.
