Stablecoins Are Taking Over – Should You Be Using Them?

In many developing nations, the rise of stablecoins is a story of necessity. Historically, restrictive banking policies and currency fluctuations have driven users toward alternative financial solutions.

In February 2021, the Central Bank of Nigeria (CBN) issued a circular directing banks to stop facilitating cryptocurrency transactions, effectively pushing crypto activity into informal channels. Users quickly shifted to peer‑to‑peer (P2P) networks and voucher‑style systems, where Nigerians could buy and sell stablecoins like USDT and USDC without relying on traditional bank rails.

By late 2023 and early 2024, the CBN reversed its stance and issued new guidelines allowing banks to provide accounts for Virtual Asset Service Providers (VASPs), signalling a move from outright restriction to regulated co‑existence rather than a permanent ban.

Today, Africa accounts for stablecoin flows equivalent to around 6.7% of GDP, one of the highest ratios globally, with Nigeria and South Africa leading the surge. For populations facing high inflation and limited access to physical dollars, stablecoins offer a practical bridge to the stable valuation of fiat currencies like the US dollar.

What Stablecoins Actually Do: Real Use Cases

Stablecoins are designed to bridge the gap between the unpredictability of native cryptocurrencies and the stability of everyday money. Here is how regular people are actually using them:

· Remittances & cross‑border payments: Sending money internationally through traditional banking networks can be slow and cost up to 10–20% in fees. Stablecoins run on blockchains 24/7, enabling global payments in minutes or hours at a fraction of the cost.

· Savings & hedging: Because they resist the extreme volatility of Bitcoin and Ether, stablecoins are widely used by Africans to protect savings against local‑currency devaluation.

· Freelancer & business payments: Digital nomads and businesses use stablecoins for borderless wage settlements and B2B commerce, cutting out foreign‑exchange fees and multi‑day settlement delays.

The Numbers Don’t Lie

Recent surveys of cryptocurrency users in Nigeria and South Africa show that nearly 80% of respondents already hold stablecoins, with more than three‑quarters planning to increase their holdings over the next year. In Nigeria, around 95% of respondents say they would prefer to be paid in stablecoins rather than in naira, highlighting a deep‑seated shift toward dollar‑denominated digital assets.

Globally, the stablecoin ecosystem is even larger. The total stablecoin market cap has climbed to about $314 billion, up from roughly $184 billion in 2022. In 2024 alone, stablecoin trading volume exceeded $25 trillion, while annual transfer volume reached about $27.6 trillion, surpassing the combined transaction volumes of Visa and Mastercard for that year.

Analysts project that the value of stablecoins in circulation could reach $1.9 trillion by 2030 in a base case, and up to $4 trillion in a bullish scenario, indicating that stablecoins are on track to become a core part of global finance.

How They Work: Pegs, Reserves, and Transparency

To use stablecoins safely, you need to understand how they hold their value. The most common ones—like Tether (USDT) and USD Coin (USDC)—are fiat-collateralised, meaning that issuers claim to back each circulating token with roughly $1 of cash or short‑term US Treasury bills held in segregated reserves.

Transparency and audits are critical. If an issuer lacks clear reporting or mismanages its reserves, users can lose confidence, causing the coin’s price to drift below $1—a so‑called “depeg” event. There have already been episodes where USDT traded slightly below parity during market stress, underscoring the importance of diversification and issuer risk assessment.

Other stablecoins, like DAI, are crypto-collateralised: they are issued and managed by decentralised protocols (such as MakerDAO) and are “over-collateralised” by other cryptocurrencies, such as Ethereum, which helps maintain the $1 peg without relying on traditional bank reserves.

The Central Bank Dilemma

Regulators care so much because stablecoins can drive currency substitution (dollarisation). When people and businesses abandon a volatile national currency in favour of US‑dollar‑backed stablecoins, the local central bank loses leverage over monetary policy and inflation management.

Because stablecoins are digital and borderless, they can accelerate capital flight and complicate the enforcement of capital controls. In response, central banks and regulators are introducing tighter rules, such as the US GENIUS Act and the EU MiCA framework, which demand adequate reserves, regular audits, and strict anti‑money‑laundering (AML) and know‑your‑customer (KYC) protocols for issuers.

Earning with Stablecoins: Yields and Risks

One major draw of stablecoins is the ability to earn interest through DeFi lending platforms such as Aave, Compound, or protocol‑integrated savings products. Yields can sometimes reach 4% or more per year in USD terms, often higher than traditional savings accounts in many emerging markets.

However, these returns are not risk‑free. Key risks include:

· No deposit insurance: Stablecoins are not protected by government‑backed schemes like the FDIC in the US or equivalent deposit guarantee schemes in most African countries.

· Platform and smart‑contract risks: Operational failures, bugs, or hacks can lead to loss of funds on centralised exchanges or DeFi protocols.

· Liquidation spirals: In DeFi, borrowers often pledge volatile crypto as collateral for stablecoin loans; if markets crash, mass liquidations can temporarily destabilise lending pools and harm lenders.

Practical Guide: Using Stablecoins Today

Here is how you can safely use stablecoins in practice:

· Where to buy: You can purchase stablecoins using fiat via global exchanges such as Binance, Coinbase, and Kraken, as well as Africa‑focused platforms like Yellow Card and local P2P markets.

· Where to store: You can hold them in custodial wallets (where the exchange controls the keys) or non‑custodial/self‑custody wallets such as MetaMask, Trust Wallet, or hardware wallets, which give you full control over your private keys.

· How to use: You can transfer them globally to any compatible wallet address, convert them to local currency via P2P or licensed exchanges, or deploy them in DeFi for yield, lending, or trading.

Because Nigerian regulations and exchange‑off‑ramp rules can change, always verify current P2P and bank‑linked off‑ramp options for naira before relying on any specific route.

Future Outlook

The stablecoin ecosystem is maturing rapidly. Analysts expect stablecoin issuance to reach between $1.9 trillion and $4 trillion by 2030, with stablecoin‑based rails supporting vast volumes of global transactions.

In the future, we will likely see:

· More multi‑collateral stablecoins (blending crypto and fiat backing).

· Central Bank Digital Currencies (CBDCs) that may interact with or compete with private stablecoins.

· Traditional financial institutions are building infrastructure for stablecoin settlements, signalling that stablecoins will likely become a permanent feature of global finance, not a passing trend.

Questions People Are Asking

“Is my money safe in USDT? What if Tether collapses?”

Tether (USDT) is the largest stablecoin and claims to be fully backed by reserves, including cash and short‑term US Treasury bills. However, it has experienced temporary “depegs” during market panics, and there is no government deposit insurance. Your safety depends heavily on reserve transparency, regular audits, and your own diversification across issuers and assets.

“Can I receive my freelance payments in USDC instead of naira?”

Yes. You can provide your client with a USDC wallet address (on Ethereum, Solana, or a lower‑fee network like Polygon). Once the USDC arrives, you can either hold it as a store of value or use P2P platforms and local exchanges to convert it into naira in your bank account. Remember to factor in blockchain network fees (gas) and choose cheaper networks where possible.

“How do stablecoins compare to keeping money in my domiciliary account?”

Stablecoins offer borderless access, faster settlements, and often higher yields via DeFi, but they lack traditional deposit insurance and regulatory protections. Domiciliary accounts are regulated banking products with local consumer‑protection frameworks, but they are subject to exchange‑control rules and may offer lower returns.

“Will the CBN ban stablecoins again?”

The CBN previously restricted banks from facilitating crypto transactions in 2021, but by late 2023 it shifted to regulating rather than outright banning crypto‑related banking services. Complete bans on decentralized networks are hard to enforce, and the global trend is toward strict regulation and integration, not sweeping prohibitions.

“What’s the difference between USDT, USDC, and DAI?”

· USDT (Tether) and USDC (USD Coin) are fiat‑collateralized stablecoins, issued by centralized firms and backed mainly by cash and US Treasury bills.

· DAI is a crypto‑collateralized stablecoin, managed by decentralized MakerDAO smart contracts and over‑collateralized by other cryptocurrencies to maintain its peg.

“Can I pay for things with stablecoins in Lagos?”

Direct stablecoin payments at everyday merchants in Lagos are still emerging, but usage is growing. Many users currently convert stablecoins to naira via P2P or local exchanges to make local purchases. However, crypto‑linked debit cards and point‑of‑sale solutions are making it easier to spend stablecoins directly at more merchants, especially in tech‑savvy communities and Afro‑centric fintech corridors.
