What is a stablecoin?

Stablecoin is a special cryptocurrency that maintains the stability of prices by "anchoring" with some stable reserve asset. The most common anchor object is fiat currency, such as the US dollar. This means that the theoretical value of a unit of stablecoin is equal to one dollar.

There are two main functions of stablecoins: one is that as a trading medium, users can use stablecoins to purchase other cryptocurrencies with price fluctuations such as Bitcoin and Ethereum without frequently converting funds between fiat and cryptocurrencies. Second, as a store of value, when the crypto market falls sharply, investors can exchange assets for stablecoins to avoid risks and wait for the market to recover.

The most mainstream stablecoins on the market include USDT (Tether), USDC (USD Coin) and BUSD (Binance USD), which all maintain a 1:1 anchor relationship with the US dollar.

How to buy stablecoins? (Taking C2C trading as an example)

The most common and convenient way to buy stablecoins on exchanges is C2C (Customer-to-Customer) transactions, that is, to purchase them directly from certified merchants on the platform. Here are the general steps:

Step 1: Register and complete identity authentication

Register an account on the official website or app of your choice (such as Binance, Ouyi). According to the platform requirements, completing identity authentication (KYC) usually requires uploading photos of your ID and facial recognition. This is a necessary link to ensure the safety of your funds and comply with anti-money laundering regulations.

Step 2: Enter the C2C trading area

After logging in to your account, you can usually find entrances such as "Buy Coins", "C2C Transaction" or "Quick Buy Coins" on the homepage of the App. After clicking to enter, select the "Purchase" option.

Step 3: Filter the transaction conditions

On the C2C Transactions page, select the type of stable currency you want to purchase (usually USDT is preferred), and then select the fiat currency you wish to use to pay for. The system will display a list of all eligible merchants.

Step 4: Select the merchant and place an order

In the merchant list, focus on price, merchant transaction volume and positive review rate. Choose a merchant with good reputation and appropriate price and click "Buy". Enter the amount (fiat currency) or quantity (stable currency) you want to purchase and “order”.

Step 5: Pay and wait for the coin to be released

After placing an order, the page will display the merchant’s collection information (such as bank card number, Alipay account number). Please pay to the merchant through your own payment account within the specified time. Do not note any information related to Bitcoin, USDT, etc. when making payment . After completing the payment, return to the trading platform and click the "I have completed payment" button, and wait for the merchant to verify and release the stablecoin. Your stablecoin will be deposited into your exchange funds account very quickly.
