What are Stablecoins in Crypto?
Stablecoins are a type of cryptocurrency designed to maintain a stable or steeady value, unlike Bitcoin or Ethereum, which can rise and fall sharply. Practically, a stablecoin is digital money that is designed to stay close to a specific price, most commonly 1 US dollar.
Stablecoins are built around a “peg” system (meaning that the value of the coin is tied to something else). In most cases, that “something” is the US dollar. So:
- 1 USDT ≈ $1
- 1 USDC ≈ $1
This peg is maintained using reserves, collateral, or automated systems, depending on the type of stablecoin.
For example, with major stablecoins like USDT (Tether), the issuing company claims to hold real-world assets such as cash or treasury bills that match the number of coins in circulation. This is why millions of people trust it for everyday use, even though it is still important to understand the risks.
From a practical standpoint, stablecoins are used because they solve a very specific problem in crypto. The problem of volatility (most cryptocurrencies are too volatile to function as money).
Imagine receiving your salary in Bitcoin. Today it might be worth ₦500,000, and next week it could drop to ₦350,000. These unpredictable fluctuations make it hard to:
- Save money
- Pay for goods
- Run a business
Stablecoins fix this by acting as a digital version of the dollar, without requiring a traditional bank.
Another thing to understand about stablecoins is that they are fully digital and blockchain-based. This means:
- You can send them instantly across countries
- Transactions are recorded publicly on a blockchain
- You don’t need a bank to hold or transfer them
For example, sending $500 worth of stablecoins from Nigeria to Ghana or the UK can take a few minutes, compared to days with traditional banks. Fees are also often lower, depending on the network used.
How Do Stablecoins Work?
Stablecoins work by using different systems to keep their price stable. The key idea behind all stablecoins is that there must be something supporting (or controlling) their value so it does not fluctuate like regular cryptocurrencies.
However, not all stablecoins achieve this in the same way. The method used is what determines how safe, transparent, and reliable a stablecoin is in real-world use.
Below are the four main types of stablecoins and exactly how each one works.
1. Fiat-Backed Stablecoins (Most Common and Practical):
Fiat-backed stablecoins are supported by real-world money, usually held in bank accounts or financial institutions.
How it works:
- A company issues the stablecoin (for example, USDT or USDC)
- For every 1 coin created, the company holds $1 (or equivalent assets) in reserve
- When users buy the stablecoin, new coins are minted
- When users redeem (sell back), coins are destroyed (burned)
👉 This system keeps the supply balanced and helps maintain the $1 value.
What backs them:
- Cash (USD)
- Bank deposits
- Short-term government securities (like U.S. Treasury bills)
Why people use them:
- Easy to understand
- Stable and widely accepted
- Best for trading, saving, and sending money
2. Crypto-Backed Stablecoins (Decentralised but More Complex):
Crypto-backed stablecoins are backed by other cryptocurrencies instead of fiat money.
How it works:
- You deposit cryptocurrency (like ETH) into a smart contract
- The system locks your crypto as collateral
- You receive stablecoins in return (e.g., DAI)
- To get your crypto back, you must return the stablecoins
The key mechanism used for this type of stablecoin is Overcollateralisation.
Because crypto prices are volatile, the system requires you to deposit more value than you receive.
Example:
- You deposit $150 worth of ETH
- You receive $100 worth of stablecoins
This extra buffer protects the system if the price of ETH drops.
Automatic liquidation:
If your collateral value falls too much:
- The system automatically sells your crypto
- This prevents the stablecoin from losing its peg
Why people use them:
- No central authority (fully decentralised)
- Transparent (runs on smart contracts)
- Popular in DeFi (Decentralised Finance)
Practical downside:
- More complicated for beginners
- Requires active monitoring
- Risk of liquidation if the market drops suddenly
3. Algorithmic Stablecoins (High Risk, System-Controlled):
Algorithmic stablecoins do not rely on real assets. Instead, they use code and supply control to maintain price stability.
How it works:
- The system monitors the price of the stablecoin
- If the price goes above $1, more coins are created (increase supply)
- If the price drops below $1, coins are removed from circulation (reduce supply)
👉 This is similar to how central banks control money supply, but done automatically with code.
Some systems also use a secondary token to absorb volatility.
Example mechanism:
- If demand drops, users are incentivised to burn stablecoins
- In return, they receive another token with potential future value
Why this is risky:
Algorithmic stablecoins depend heavily on market confidence. If users lose trust:
- Everyone tries to sell at once
- The system cannot maintain the peg
- The price collapses
This has happened before in major crypto failures, leading to billions in losses.
Practical takeaway:
- Not suitable for beginners
- Not reliable for storing value
- Mostly used for experimentation or advanced trading
4. Commodity-Backed Stablecoins (Asset-Based Stability):
Commodity-backed stablecoins are backed by physical assets like gold, oil, real estate, or other commodities.

How it works:
- Each stablecoin represents ownership of a real-world asset
- The asset is stored by a custodian (e.g., gold in a vault)
- The value of the stablecoin follows the price of that commodity
Example:
- 1 token = 1 gram of gold
If gold price increases, the value of the stablecoin also increases.
Why people use them:
- Hedge against inflation
- Exposure to commodities without physically owning them
- More stable than crypto, but not fixed like USD-backed coins
Practical limitations:
- Not as widely used as fiat-backed stablecoins
- Less liquid (harder to trade quickly)
- Requires trust in the storage and auditing of the physical asset
Why Stablecoins Matter to Crypto Traders (Especially in Nigeria)
1. Safe Parking Spot During Market Volatility:
Crypto prices can change very quickly. For example:
- You buy Bitcoin at $60,000
- The market starts dropping
- You don’t want to lose value
Instead of converting back to naira (which can be slow or costly), you simply convert your Bitcoin to USDT.
Now:
- Your funds are stable (still around $1 per USDT)
- You are protected from further price drops
- You are ready to re-enter the market at a better price
👉 This is called “moving to stablecoins,” and it is one of the most common strategies used by traders.
2. Direct Access to Dollar Value Without a Bank:
In Nigeria, accessing USD through traditional banks can be difficult due to:
- Foreign exchange restrictions
- Limited availability of dollars
- High conversion costs
Stablecoins solve this instantly.
Instead of trying to open a domiciliary account or buy dollars physically, traders simply:
- Convert naira to USDT
- Hold and trade in USD value
👉 This makes stablecoins a practical alternative to holding actual dollars.
3. Main Trading Pair in Crypto Markets:
Most crypto exchanges do not use naira directly. Instead, they use stablecoins like USDT as the base currency.
This means:
- You don’t trade BTC/NGN
- You trade BTC/USDT
So, if you want to:
- Buy Bitcoin
- Sell Ethereum
- Swap any crypto
You will most likely need stablecoins.
👉 Without stablecoins, trading access becomes limited and inefficient.
4. Fast Entry and Exit:
Timing is very important in trading. Opportunities can appear and disappear within minutes.
With stablecoins:
- You can enter trades instantly
- You can exit without waiting for bank processing
- You avoid delays linked to fiat withdrawals
For Nigerian traders, this is critical because:
- Bank transfers can fail or delay
- Payment systems may be restricted
- Market opportunities do not wait
Stablecoins remove these limitations.
5. Reduced Transaction Friction and Cost:
Moving money through traditional systems often involves:
- Transfer fees
- Exchange rate losses
- Delays
With stablecoins:
- Transfers are faster
- Fees are often lower (depending on network)
- You maintain dollar value throughout
For active traders, these small savings add up significantly over time.
6. Better Risk Management:
In trading, risk management is everything. Stablecoins allow traders to:
- Lock in profits after a successful trade
- Avoid emotional decisions during market swings
- Maintain liquidity for future opportunities
Example:
- You make $500 profit on a trade
- You convert to USDT immediately
Now:
- Your profit is secured
- You are not exposed to sudden market drops
👉 This discipline is what separates consistent traders from losing traders.
7. Cross-Border Trading and Arbitrage Opportunities:
Some traders take advantage of price differences across platforms or countries.
With stablecoins, you can:
- Move funds between exchanges globally
- Buy low in one market and sell high in another
- Take advantage of pricing inefficiencies
This is especially useful in Nigeria, where local prices can differ from global markets.
8. Reliable Hedge Against Naira Depreciation:
Even outside trading, many Nigerian traders hold stablecoins simply to protect their capital.
For example:
- You keep trading capital in naira
- The naira weakens
- Your buying power reduces
But if your funds are in USDT:
- Your capital remains tied to USD
- You maintain consistent trading power
👉 This stability is critical for long-term trading success.
