How to Select a Cryptocurrency Exchange: Top 5 Recommendations for International Platforms

Is It Illegal to Use Overseas Cryptocurrency Exchanges?

Is it illegal to use overseas cryptocurrency exchanges from within Japan? The short answer is no—Japanese residents are not prohibited from using overseas cryptocurrency exchanges. Under current Japanese law, cryptocurrency exchanges must register with the Financial Services Agency (FSA) to operate domestically, but there are no direct regulations on end users. Simply using an overseas exchange is not a violation of the law.

Legal Framework

The Payment Services Act in Japan requires crypto asset exchange operators to register with the Prime Minister. This rule applies to service providers, not individual users. Operating an unregistered exchange is illegal, but Japanese residents using unregistered exchanges face no legal restrictions.

However, just because there are no legal issues does not mean there are no risks. Overseas exchanges present unique security and asset protection challenges compared to domestic platforms.

Registration Status and Misconceptions About Overseas Exchanges

Many overseas cryptocurrency exchanges are not registered with Japan’s FSA, causing some Japanese users concern. Furthermore, some exchanges have been subject to FSA administrative actions in the past, leading to restrictions that prevent Japanese users from accessing certain platforms.

These cases fuel a common misconception that “overseas exchanges = illegal.” However, as stated above, Japanese law does not prohibit individuals from using unregistered exchanges. Still, if an exchange actively markets to Japanese users, it may be subject to regulation, making sudden service suspensions a constant risk.

Security Precautions

Overseas exchanges not registered with the FSA can pose security risks, such as hacking, fraudulent cryptocurrencies, service suspensions, or asset freezes.

When using an overseas exchange, always review the exchange’s track record, security measures, and incident history. Also, diversify your assets and avoid leaving more funds on the platform than necessary.

Key Factors When Choosing a Cryptocurrency Exchange

When choosing a cryptocurrency exchange, you should evaluate several key factors. Below are five important points to consider in detail.

1. Security Strength

Security is the top priority in crypto trading. Protecting client assets is essential, so it’s critical to review what security measures an exchange has in place.

Check for these security features:

• Two-Factor Authentication: Adds a layer of protection at login or withdrawal to prevent unauthorized access.
• SSL Encryption: Encrypts data transmission to prevent eavesdropping or tampering.
• Cold Wallet Storage: Keeps the majority of client assets offline, reducing hacking risk.
• Multi-Signature Mechanisms: Requires multiple signatures for transactions to prevent unauthorized fund movement.

Also, verify server stability, anti-hacking safeguards, 24/7 monitoring, and quality support. Trading is more secure when these protections are in place.

2. Variety of Supported Assets

The number of cryptocurrencies available is another key factor. While most exchanges support Bitcoin and Ethereum, altcoin offerings vary widely. A broader selection means more investment opportunities and better portfolio diversification.

Key considerations include:

• Major Altcoins: Does the exchange carry top-market-cap assets like Ethereum, Ripple, and Litecoin?
• Early Access to New Projects: Can you trade promising new project tokens early?
• DeFi and NFT Tokens: Are the latest trend tokens available?

If you want future growth opportunities, choose an exchange with broad asset coverage. However, more tokens can also mean lower-liquidity assets, so always check trading volumes and liquidity.

3. Fees Comparison

Fees are a vital consideration. Crypto trading involves various fee types, so understand each and look at the total cost.

Main fees include:

• Trading Fees: A percentage of each transaction when buying or selling assets.
• Spread: The price gap between buy and sell on brokerage-style exchanges, representing effective trading cost.
• Deposit Fees: Fees for depositing money into the exchange.
• Withdrawal Fees: Fees charged for taking money off the exchange.
• Transfer Fees: Fees to send crypto assets to other wallets or exchanges.

Compare exchanges to see which offers the lowest long-term costs. For frequent traders, even small fee differences add up. Some exchanges offer discounts for holding native tokens, so consider these perks too.

4. Usability and Convenience

The usability of trading tools is critical for trading success. In the volatile crypto market, a smooth interface helps you execute quickly without missing opportunities.

Evaluate these usability points:

• Intuitive Interface: Simple, beginner-friendly layout.
• Comprehensive Mobile App: Feature-rich mobile trading for on-the-go activity.
• Diverse Order Types: Does the exchange support market, limit, and stop orders?
• Advanced Charting Tools: Are technical indicators and drawing tools available?
• Japanese Language Support: Menus, help, and support available in Japanese.

Simple exchanges are best for beginners, but as your expertise grows, you may need more advanced tools. Choose a platform that can grow with you.

5. Reliability and Regulatory Compliance

Lastly, verify the exchange’s reliability and transparency. To safely use overseas exchanges, check for the following:

Reliability factors:

• Operational Track Record: Years in business and history of stable operation.
• User Base: Global user numbers and trading volume.
• Transparency: Publication of due diligence or Merkle tree proof reports.
• Regulatory Status: Is the exchange licensed by financial regulators?
• Incident History: Any past security breaches or asset leaks and how they were handled.

Transparency Through Due Diligence

Due diligence is a third-party investigation of a company or project’s risks, with findings publicly disclosed. This helps investors and partners understand risks and increases transparency regarding operations and finances. Exchanges that regularly release due diligence results are generally more trustworthy.

Merkle Trees for Enhanced Transparency

Merkle tree structures record blockchain data hierarchically, enabling efficient verification of overall data integrity. This makes tampering easy to spot and strengthens transparency for both transactions and asset management. Exchanges that publish Merkle tree-based Proof of Reserves can prove proper asset custody and boost user trust.

Pros and Cons of Using Overseas Cryptocurrency Exchanges

Overseas exchanges offer unique benefits not found in domestic platforms, but also come with specific drawbacks. Here’s a closer look at both.

Advantages of Overseas Cryptocurrency Exchanges

1. Extensive Asset Variety

Overseas exchanges list far more cryptocurrencies than domestic ones, with hundreds or even thousands of assets available on major platforms.

Advantages include:

• Early Access to New Projects: Buy tokens from promising projects before they’re listed in Japan.
• Diversified Investments: Spread risk across different sectors and use cases.
• Lead Market Trends: Access trending tokens before they hit domestic exchanges.

A broader selection can also include illiquid or fraudulent projects, so always do thorough research—read whitepapers, check the dev team, and monitor community activity before investing.

2. Lower Spreads and Fees

Overseas exchanges tend to have tighter spreads than domestic ones, which means lower effective transaction costs.

Cost benefits include:

• Lower Trading Fees: Many exchanges set fees around 0.1%.
• Tighter Spreads: Lower buy-sell gaps help reduce trading costs.
• Fee Discounts: Many platforms offer discounts for holding native tokens or based on trading volume.

Low spreads and fees are especially advantageous for short-term traders. For long-term holders, the impact is less, but for day traders or scalpers, fee differences can have a big effect on profits.

3. High Leverage Trading

Overseas platforms often offer leverage far above Japan’s 2x cap—some support 100x or more, letting traders open large positions with relatively little capital.

Benefits of high leverage:

• Capital Efficiency: Trade more with less up-front capital.
• Diverse Strategies: High leverage enables a range of trading tactics.
• Zero Cut System: Many overseas exchanges implement automatic liquidation to prevent losses beyond margin, minimizing margin call risk.

Note that high leverage increases both potential gains and losses. Crypto’s volatility means you must have strong risk management, experience, and knowledge before using high leverage.

Disadvantages of Using Overseas Exchanges

1. Language Barrier in Support

Some overseas exchanges only provide customer support in English. While Japanese support is becoming more common, if it’s not fully available, users may face these issues:

• Difficulty Communicating: Problem resolution may require English.
• Risk of Misunderstandings: Key notices or policy changes may be hard to interpret.
• Slower Responses: Japanese inquiries may be delayed due to translation steps.

For general trading, this may not be an issue, but for support needs, you may need translation tools or basic English skills. Always check whether the exchange offers Japanese support and its availability.

2. No Direct Yen Withdrawals

Most overseas exchanges do not support direct withdrawals to Japanese bank accounts. To get yen, you typically must:

1. Sell crypto on the overseas exchange for stablecoins or major cryptocurrencies
2. Transfer those assets to a domestic exchange
3. Convert to yen on the domestic exchange
4. Withdraw from the domestic exchange to your bank account

This process involves:

• Extra Steps and Time: Withdrawals take longer due to multiple steps.
• Extra Fees: Transfer and domestic exchange selling fees may apply.
• Price Fluctuation Risk: Asset values may change during transfer.

Some overseas exchanges support credit card deposits or specific payment service withdrawals, but these typically have higher fees—always check the details in advance.

3. Hacking Risks

Overseas exchanges, like all platforms, are vulnerable to hacking. Several major players have suffered large-scale asset losses.

Risk mitigation tips:

• Diversify Assets: Don’t keep everything on one exchange—use multiple platforms and wallets.
• Use Cold Wallets: Store long-term holdings offline.
• Review Security Features: Check for two-factor authentication, cold wallet management, etc.
• Keep Minimal Funds on Exchange: Only keep what you need for trading; move the rest to safer storage.

No security system is perfect. Always maintain a strong sense of personal responsibility and apply careful risk management.

4. Risk of Sudden Service Suspension

Overseas exchanges may halt service for users in certain countries due to regulatory action or business decisions. In Japan, this has occurred in the past:

• Regulatory Action: Suspension of service following FSA warnings or guidance.
• Business Strategy: Withdrawal from the Japanese market and closure of local accounts.
• Legal Changes: Japanese law changes could restrict overseas exchange use.

Prepare for this risk by:

• Staying Informed: Follow official exchange announcements and monitor Japanese regulations.
• Using Multiple Exchanges: Don’t rely on a single platform—maintain accounts elsewhere.
• Preparing for Fast Asset Transfers: Be ready to move funds quickly if service is suspended.

Since Japanese access can be unstable, always be alert to possible suspensions and regulatory changes, and remain ready to adapt.

Understanding the Travel Rule: A Must When Using Overseas Exchanges

The Travel Rule is an international standard that requires exchanges to transmit detailed sender and recipient information to counterparties during crypto transfers. In Japan, the Travel Rule was implemented through recent anti-money laundering law amendments, and domestic exchanges must now comply—significantly affecting users.

Travel Rule: The Basics

The Travel Rule, as set by the FATF (Financial Action Task Force), requires the following information for crypto transfers:

• Sender’s name
• Sender’s account number (or wallet address)
• Sender’s address
• Recipient’s name
• Recipient’s account number (or wallet address)

Sharing this data between exchanges makes illicit fund flows easier to trace and prevents money laundering.

1. Detailed Transfer Information Now Required

With the Travel Rule in place, sending crypto from a domestic to an overseas exchange now requires more detailed information than before.

Typically required information:

• Sender ID: Name, date of birth, address, etc.
• Recipient Info: Exchange name, recipient’s name, wallet address.
• Transfer Purpose: Reason or intended use.
• Customer ID Number: Unique ID issued by each exchange.

Requirements may differ by exchange, so always check in advance. Input mistakes can cause delays or, in a worst-case scenario, loss of funds.

2. Transfers Blocked Between Incompatible Solutions

Domestic exchanges use different technical solutions for the Travel Rule, like "TRUST" and "Sygna." You cannot transfer funds between exchanges using incompatible systems.

How to handle this:

• Check Solutions Before Transfer: Ensure both sending and receiving exchanges use the same system.
• Choose Compatible Exchanges: Some major overseas exchanges use solutions compatible with Japan’s system—choose these where possible.
• Consider Intermediary Exchanges: If direct transfer isn’t possible, use an intermediary exchange that bridges both solutions.

Always confirm which solution your overseas exchange supports before sending funds.

3. Some Crypto Assets Cannot Be Transferred

Even if a domestic exchange lists a crypto asset, not all tokens can be sent to overseas exchanges due to Travel Rule restrictions.

Reasons include:

• Delayed Technical Implementation: Some tokens aren’t yet supported by Travel Rule-compliant systems.
• Exchange Policy: For risk management, some assets are restricted from overseas transfers.
• Regulator Guidance: The FSA may direct exchanges to block certain asset transfers.

Commonly supported assets include:

• Bitcoin (BTC)
• Ethereum (ETH)
• Ripple (XRP)
• Other leading altcoins

Check your domestic exchange’s website for the latest list of Travel Rule-compliant assets before any overseas transfer. Supported tokens may change, so review updates regularly.
