Forex, short for foreign exchange, refers to the exchange and price relationship between different national currencies. The exchange rate can be understood as “quoting one currency in terms of another”—for example, USD/CNY indicates how many Chinese yuan you get for one US dollar.
Forex rates are typically quoted in pairs, known as “currency pairs.” In practical terms, if you exchange $100 at a bank for Chinese yuan, the difference between the buying and selling prices listed at the counter is called the “spread.” This spread reflects both service fees and overall market supply and demand. At its core, forex is about price discovery (the market consensus on future value) and risk management (reducing uncertainty caused by currency fluctuations).
The forex market operates as a decentralized, over-the-counter global network. Banks, financial institutions, businesses, and individuals match trades via electronic systems, running nearly 24 hours a day on business days.
Prices are driven by supply and demand, interest rates, inflation, and policy expectations. You’ll encounter two types of prices: the bid (buy price) and the ask (sell price); the difference between them is the spread. “Liquidity” refers to how quickly you can transact at or near the listed price—the more participants and deeper the capital pools, the higher the liquidity. In some scenarios, “leverage” is used, meaning borrowed funds are used to amplify positions; however, leverage also increases potential losses, so beginners should exercise caution.
Forex and crypto are closely connected because the crypto market extensively uses “stablecoins” as units of account. Stablecoins are tokens pegged to fiat currencies—most commonly the US dollar—and are designed to maintain relatively stable purchasing power on-chain.
On the trading side, many crypto assets are priced in USDT and other stablecoins, effectively bringing “dollars” onto the blockchain. In terms of use cases, freelancers can receive payments in stablecoins and then convert them to local currency; businesses can leverage stablecoins for cross-border settlements, reducing settlement times and some intermediary costs. For individual wealth management, stablecoins can temporarily serve as a substitute for traditional currency exchange—but users must comply with local forex and tax regulations.
Stablecoins can facilitate forex-like transactions in a compliant manner. The general process is: purchase stablecoins via supported fiat channels → exchange for your desired currency within the platform → transfer on-chain or cash out locally.
Step 1: Register an account on Gate and complete identity verification (KYC). KYC involves submitting personal information as required for anti-money laundering (AML) and compliance checks; available regions are listed in platform announcements.
Step 2: Purchase USDT or USDC through compliant fiat channels. Pay attention to payment methods, transaction fees, and settlement times; also confirm local compliance requirements and limits.
Step 3: On Gate’s spot exchange, swap USDT for your target stablecoin or asset (if a direct pair with euro stablecoin or other targets is available, exchange directly; otherwise, convert to USDT first, then to your desired currency).
Step 4: For cross-border transfers, withdraw your target stablecoin to the recipient’s specified wallet network. When selecting a network, consider “on-chain fees” (commonly known as “gas fees,” which are required to process transactions on the blockchain) and settlement speed.
Step 5: Manage and record your funds. Keep records of deposits, exchanges, and withdrawals for reconciliation, tax filing, and compliance purposes; confirm in advance that recipients can legally accept funds.
Note: Stablecoins and forex are subject to different regulations across jurisdictions. Always operate within local laws. For large transactions or business use cases, consult professional compliance and tax advisors beforehand.
The main risks in forex include exchange rate volatility, interest rate differentials, liquidity shortages, counterparty risk, and compliance risk. In stablecoin scenarios, you should also watch for “de-pegging” (when a stablecoin’s price deviates from its fiat peg) and smart contract vulnerabilities.
If you expect to spend or account in one currency in the future but are currently holding another, you have a currency risk exposure. For example, if you’ll need to spend locally in 30 days but your income is in USD, holding stablecoins can serve as a short-term hedge to reduce uncertainty from local currency depreciation. If you use leveraged derivatives like “contracts” for hedging, be clear about margin requirements, liquidation thresholds, and slippage impacts to avoid over-leveraging. Common strategies include: diversifying across multiple stablecoins, setting stop-loss orders (automatically reducing positions if price hits a certain level), using limit orders, and maintaining ample cash flow to handle short-term fluctuations.
On-chain forex relies primarily on “oracles” and automated market making mechanisms. Oracles securely deliver off-chain price data onto the blockchain for contract settlement and liquidation; automated market makers (AMMs) use liquidity pools and pricing algorithms instead of traditional order books.
When exchanging USDT for another stablecoin, the depth of the liquidity pool determines how closely the on-chain price matches external forex rates; if liquidity is low or there is heavy one-sided trading, transaction prices may deviate from expectations—this deviation is known as “slippage.” Additionally, if a stablecoin temporarily “de-pegs,” on-chain forex prices can diverge from interbank rates. Common best practices include: selecting pools or platforms with greater liquidity depth, splitting large trades into smaller ones, setting limit orders during high volatility periods, and referencing multiple price sources when necessary to avoid pricing errors.
Cross-border fund flows are subject to forex controls, anti-money laundering (AML), and know-your-customer (KYC) regulations. Using crypto assets does not exempt users from these obligations.
Individuals and businesses should focus on three key areas: First, verify which stablecoin use cases, currency exchanges, and crypto payments are permitted locally; second, choose compliant channels with proper licensing and cooperate with identity and source-of-funds verification; third, keep detailed transaction records—including payment receipts and reconciliations—to meet tax and audit requirements. For large transactions or multi-jurisdictional operations, consulting professional advisors is strongly recommended.

Forex and crypto are rapidly converging—leading to faster settlements, extended trading hours, and more transparent on-chain reconciliation. Regulatory frameworks for stablecoins are being rolled out in stages globally between 2024–2025, bringing clearer industry compliance standards (source: official regulatory announcements).
Looking ahead 1–3 years, expected trends include: further tokenization of fiat currencies and other assets resulting in richer “on-chain forex” trading pairs; institutional adoption of on-chain settlement and cross-border payment pilots; some central banks continuing cross-border CBDC cooperation pilots through 2023–2025 (source: public central bank/international reports); ongoing iterations in oracle and clearing technology to improve pricing reliability and risk management capabilities. However, technology and regulations remain in flux—products and policies may change—so users should always assess risks and compliance requirements before allocating capital.
Forex volatility directly impacts your exchange rate costs—a 1% rate swing could mean spending or saving hundreds of units of your local currency. For example: transferring $1,000 abroad at an exchange rate moving from 7.0 to 7.1 means paying an extra 70 yuan. To manage this risk, consider transacting during periods of low volatility or using stablecoins (such as USDT) to lock in your exchange rate.
Crypto stablecoins offer three major advantages over traditional forex: around-the-clock trading (banks operate on limited hours), lower and more transparent transaction costs (no hidden spreads), and faster settlement (minutes versus days). For those making frequent cross-border transfers, using USDT on Gate can help save significant bank fees and time.
Consider these three approaches: First, review historical trends to identify lower points (though perfect timing is difficult); second, avoid periods with high volatility like late Friday evenings or early Monday mornings; third, if you need funds soon, do not wait excessively since exchange rates are hard to predict. Regular small exchanges often yield better results than trying to time one large conversion perfectly.
The spread is the difference between the buying (bid) and selling (ask) prices—this is bank profit. Fees are additional charges on top. For example: if the buy rate is 6.95 yuan per dollar and sell rate is 7.05 yuan per dollar, the 0.10 difference is the spread; an extra 0.5% would be a fee. Platforms like Gate provide high transparency with no hidden spreads—fees are clearly displayed.
You don’t have to be a professional trader to benefit from forex opportunities. The most practical approach is to use Gate’s stablecoin features for daily cross-border needs while learning basic exchange rate principles (like interest rate differentials and economic indicators). This helps you avoid high risks associated with professional trading while enabling smarter conversion decisions when needed.
