Top Overseas Cryptocurrency Exchanges for Korean Traders

Why Use Overseas Cryptocurrency Exchanges

Overseas cryptocurrency exchanges refer to trading platforms that operate with relatively fewer restrictions compared to domestic Korean regulations. These exchanges primarily facilitate trading using stablecoins such as USDT (Tether). Additionally, they offer access to cryptocurrency derivatives like margin futures, making advanced trading strategies readily accessible to users.

For Korean investors seeking to maximize their trading opportunities, overseas exchanges provide several distinct advantages. These platforms enable access to a broader range of digital assets, advanced trading tools, and competitive fee structures that may not be available on domestic exchanges. Understanding these benefits is crucial for making informed decisions about where to trade.

Trading Unlisted Domestic Coins

Domestic Korean cryptocurrency exchanges, particularly the five major platforms that support Korean won (KRW) trading, have adopted increasingly conservative listing policies in recent years. These exchanges typically wait for global market validation before listing new tokens domestically.

This conservative approach effectively positions Korean investors as secondary market participants. Coins that have already experienced significant price appreciation on overseas exchanges are then introduced to the Korean market, where they may see additional price increases before becoming accessible to domestic investors. To overcome this disadvantage, it is essential to identify promising coins and acquire them on global markets before they are listed domestically.

For example, many altcoins that eventually gain popularity in Korea first establish liquidity and trading volume on international platforms. By the time these assets reach Korean exchanges, early adopters on overseas platforms may have already captured substantial gains. This timing difference underscores the importance of maintaining accounts on both domestic and international exchanges.

Diverse Cryptocurrency Derivatives

Cryptocurrencies are known for their high volatility, meaning prices fluctuate significantly both upward and downward, even when maintaining a similar price range.

Consider a scenario where Bitcoin's price is moving sideways within a specific range. In such cases, spot investors typically adopt a holding strategy, as there are no meaningful profits to be gained from price consolidation.

However, investors utilizing cryptocurrency derivatives can maximize profits by leveraging the upward and downward price movements within the sideways range. This means significant gains can be achieved even when the opening and closing prices are identical. This is the appeal of cryptocurrency derivatives.

Derivatives trading allows for strategies such as short selling during downtrends and leveraged long positions during uptrends. These tools enable traders to profit in various market conditions, including ranging markets where spot holders see no returns. Advanced traders often employ complex strategies like hedging, arbitrage, and spread trading to optimize their risk-reward profiles.

'Kimchi Premium' Arbitrage Opportunities

Korean investors are likely familiar with the 'Kimchi Premium,' which refers to the price difference between cryptocurrencies traded in Korea and their global market prices. During Bitcoin bull markets, the Kimchi Premium can reach as high as 20%.

Investors using overseas exchanges can capitalize on such high premiums with relatively low risk and potentially significant profits. The strategy involves purchasing coins on international platforms and transferring them to domestic Korean exchanges to sell at a premium.

This arbitrage opportunity arises from several factors, including regulatory differences, capital controls, and varying levels of demand between Korean and international markets. However, it is important to note that arbitrage opportunities may be short-lived as market efficiency improves and transaction costs must be carefully considered.

Considerations When Using Overseas Exchanges

Sufficient Liquidity

Cryptocurrency exchanges must provide sufficient liquidity to ensure that buy and sell orders can be executed at desired price points without slippage. At the same time, trading fees should remain reasonable, and the platform should offer appropriate investment-related information and tools.

In Korea, exchanges like Upbit and Bithumb offer low fees and abundant liquidity, while others may have poor liquidity relative to their fee structures. The situation is similar for global exchanges. It is crucial to select an exchange that offers both sufficient liquidity and features that align with your trading needs.

The most common indicator of liquidity is trading volume. For the Bitcoin-USDT pair, leading global exchanges typically have the highest trading volumes. However, for altcoin pairs, certain coins may have higher trading volumes on specific exchanges rather than the largest platforms. If you plan to primarily trade a particular coin, it makes sense to choose an exchange that offers the best liquidity for that asset.

Liquidity also affects price stability and the ability to execute large orders without significant market impact. Low liquidity can lead to wider bid-ask spreads and increased slippage, which can erode trading profits over time.

Diverse Trading Options

In Korea, exchanges with meaningful liquidity and the largest number of listed coins, such as Upbit and Bithumb, support approximately 200-300 trading pairs. In contrast, major global exchanges offer around 400 different coins, with over 1,400 trading pairs available.

Historically, cryptocurrencies that have shown the highest short-term appreciation rates have been small-cap coins with relatively low market capitalizations. To achieve high investment returns, it is necessary to identify promising opportunities among various small and mid-cap coins. Using exchanges that support a wider range of trading pairs makes it easier to seize these opportunities.

Diverse trading options also include access to different trading types such as spot trading, margin trading, futures, options, and perpetual contracts. Some exchanges also offer innovative products like leveraged tokens, which provide leveraged exposure without the risk of liquidation.

Exchange Trustworthiness and Features

Most overseas exchanges do not offer complete Korean language support. While this may cause concern for investors who are not proficient in English, these platforms typically operate comprehensive customer support services, including FAQs and multi-tiered assistance.

However, it is important to carefully research whether an exchange supports the features you need and to choose a platform with the best performance in those areas. Exchanges may discontinue certain features or services based on market competition and regulatory changes.

Trustworthiness can be evaluated through several factors, including the exchange's history, security track record, regulatory compliance, insurance coverage for user funds, and transparency in operations. Established exchanges with long operational histories and strong security measures are generally more reliable.

Fee Verification

Overseas exchanges generally have higher fee rates compared to domestic Korean exchanges. Additionally, fees often differ between buying (taker) and selling (maker) orders. For investors who trade frequently with smaller amounts, it is essential to compare fees across platforms.

Fee structures can include trading fees, deposit fees, withdrawal fees, and network fees for blockchain transactions. Some exchanges offer tiered fee structures where higher trading volumes result in lower fees. Additionally, holding the exchange's native token may provide fee discounts, making it worthwhile to consider for active traders.

Precautions When Using Overseas Exchanges

Typically, Korean investors using overseas exchanges deposit Korean won into domestic cryptocurrency exchanges and convert it into cryptocurrency. They then transfer this cryptocurrency to overseas exchanges via inter-exchange transfers. This process requires having an account with a domestic exchange.

Verify Domestic Exchange Whitelist Registration

Under current regulations, when transferring cryptocurrencies from domestic exchanges to overseas destinations, the whitelist system must be used. The whitelist system requires pre-registration of external wallet addresses before withdrawals can be made. Only wallets in your own name can be registered, and the verification process may take some time.

Therefore, if you have never transferred coins to an overseas exchange before, it is advisable to plan your transfer with sufficient lead time. The whitelist verification process typically involves submitting identification documents and may require 24-48 hours for approval.

Decide Which Coin to Transfer

For transferring cryptocurrencies overseas, Tron (TRX) and Ripple (XRP) are commonly used. These cryptocurrencies have short block generation times, allowing inter-exchange transfers to be completed in as little as a few minutes.

In rare cases where large amounts are being transferred, some investors opt for Bitcoin transfers. Since inter-exchange transfers use on-chain networks, unexpected situations can occur. It is always recommended to first send a small test amount to verify that the transfer works correctly before sending the remaining balance.

Other popular transfer options include Litecoin (LTC) and Stellar (XLM), which also offer fast transaction times and low fees. The choice of transfer currency should balance factors such as transaction speed, network fees, and the availability of trading pairs on both the sending and receiving exchanges.

Beware of Exchanges That May Halt Withdrawals or Go Bankrupt

In November 2022, FTX, which was the second-largest exchange by trading volume globally, filed for bankruptcy. From the time rumors of crisis first emerged to actual bankruptcy, only one week passed. Investors using overseas exchanges should verify in advance whether the exchange they use is at risk of suddenly going bankrupt or shutting down.

Warning signs of exchange instability include sudden changes in withdrawal policies, unexplained delays in processing withdrawals, lack of transparency in financial reporting, regulatory investigations, and significant departures of key executives. Diversifying holdings across multiple exchanges and avoiding keeping large amounts on any single platform can help mitigate these risks.
