How to buy bitcoin in South Korea: one exchange, one bank, and know the transfer rules

01South Korea market passport

Buying bitcoin in South Korea works differently from anywhere else in Asia. You can't fund an exchange from just any bank: each exchange partners with exactly one bank, and you need a real-name verified deposit and withdrawal account (실명확인 입출금계정) at that bank. This "one bank, one exchange" system has made the Korean market extremely concentrated. It also means Korean prices often drift away from global ones, which is the famous kimchi premium.

02Regulation: KoFIU reporting and the Virtual Asset User Protection Act

Holding and trading crypto is legal in South Korea. Under the Act on Reporting and Using Specified Financial Transaction Information (특정금융정보법), every virtual asset service provider (VASP) must report to the Korea Financial Intelligence Unit (KoFIU). Conditions include ISMS information-security certification and, for a won market, a real-name account partnership with a bank. There are 28 registered VASPs, but only five offer won markets: Upbit, Bithumb, Coinone, Digital X (formerly Korbit) and Gopax.

Foreign exchanges must report too if they offer Korean-language service, market to Koreans or support won. KoFIU has in the past blocked websites and app-store listings of unregistered foreign exchanges.

The Virtual Asset User Protection Act (가상자산이용자보호법), in force since 19 July 2024, tightened things further. Exchanges must keep at least 80% of user crypto in cold wallets, customers' won deposits are held by banks and segregated from exchange funds, and insider trading, market manipulation and fraud are explicitly banned. The first criminal conviction brought three years in prison and a ₩500 million fine. The next step, a Digital Asset Basic Act (DABA) with rules for won stablecoins, is still before the National Assembly; the FSC wants a merged bill passed by the end of 2026. Spot bitcoin ETFs are still not allowed.

Corporate accounts: under the FSC roadmap of 13 February 2025, phase one is in force. Law-enforcement agencies, non-profits and universities at least five years old, and exchanges themselves may sell crypto. Phase two would cover about 3,500 listed companies and professional investors, with a proposed cap of 5% of equity per year in the top 20 coins. As of the latest reports, it has not started.

03How Koreans buy crypto: buying on Upbit step by step

Take Upbit, the market leader. Buying on Upbit (업비트 구매 방법) comes down to five steps. Other exchanges follow the same flow with a different partner bank.

1. Download Upbit and verify your identity

   Complete mobile-phone identity verification and submit your ID as requested.

2. Open an account in your own name at K Bank

   Upbit’s partner bank is K Bank. New accounts may start as “limit accounts” (한도계좌) with low initial deposit caps.

3. Link the account in Upbit and set up two-channel authentication

   You can only deposit and withdraw once it is linked. Minimum deposit ₩5,000; caps of ₩100m per transaction and ₩500m per day.

4. Buy on the KRW market

   Upbit has 290 won markets. Normal orders cost 0.05% maker and taker; reserved orders cost 0.139%.

5. Decide whether to withdraw

   Before sending to a personal wallet or an overseas exchange, make sure the address is registered and the platform is whitelisted. Won withdrawals cost ₩1,000.

So if you want to use both Upbit and Bithumb, you need two bank accounts. Partner banks and fees side by side are in the best crypto exchanges in South Korea.

Credit and debit cards: since 2018 Korean card issuers have generally refused crypto purchases, and local exchanges do not offer card buying. P2P: Korean exchanges have no P2P market, and informal currency swaps (환치기) are illegal. People who want USDT usually just buy it on a won exchange's USDT/KRW market: in the 12 months to June 2025, won purchases of stablecoins reached $64 billion. More in buying crypto by bank transfer.

04The kimchi premium: why coins cost more in Korea

The kimchi premium (김치 프리미엄, or 김프 for short) is the gap between won prices on Korean exchanges and global dollar prices. The cause is no mystery. Capital controls keep foreign money from flowing in freely, and with one bank per exchange, arbitrageurs can't move funds quickly. So when the market runs hot, Korean retail demand pushes prices above global levels: premiums of more than 20% appeared in 2018 and 2021. In weak markets the gap can flip into a discount (역프).

For an ordinary buyer, this means you may pay more than the global price on a won exchange. Many people compare the USDT/KRW price with the dollar exchange rate to gauge it. We don't forecast where the premium goes. Our one warning: don't move to an unregistered offshore platform because coins "look cheaper abroad". You give up the protection of Korean law when you do.

05The Travel Rule and blocked foreign exchanges

South Korea was the first jurisdiction to write the FATF Travel Rule into law, in March 2022. The current rule uses a ₩1 million threshold: Upbit allows transfers of ₩1 million or more only to and from whitelisted VASPs and verified personal wallets. According to Upbit's official guide (version of 23 September 2026), platforms fall into three groups:

• Deposits and withdrawals allowed: Binance, OKX, Bybit, Bitget, Gate, Crypto.com, Backpack and others.
• Deposits into Upbit only: Coinbase, Kraken, Okcoin, bitbank and others.
• Unregistered (미신고), blocked both ways: KuCoin, MEXC, Phemex, XT, Bitrue, CoinW, CoinEx, Poloniex, BTCC, DigiFinex, Pionex, BingX and more.

The rules are getting stricter. On 11 August 2026 the Cabinet approved an amendment that removes the ₩1 million threshold from 20 February 2027. Every VASP-to-VASP transfer will then carry sender and recipient details, offshore and self-custody transfers will be handled on a risk-tiered basis, and transfers to high-risk counterparties will be banned. So the answer to the common "Upbit to Binance Travel Rule" question is: yes, you can transfer, but pick the right platform and enter the beneficiary details correctly, and soon even small amounts will be covered. The full process is in our Travel Rule guide.

06Overseas exchanges and international platforms: can you use them?

Buying bitcoin on an overseas platform (해외에서 비트코인 구매) is a grey zone in Korea. Binance entered the country by buying Gopax, with KoFIU approving the change of ownership in October 2025. OKX holds 20% of Coinone through OKX Ventures, and Crypto.com has a locally registered Korean entity. But the global sites of Binance, OKX and Bybit are not reported to KoFIU themselves, and serving Koreans carries legal risk. Korea will also exchange crypto data under the OECD's CARF framework, so offshore trades come into view for tax.

CEX.IO deserves a clear explanation. It accepts residents of South Korea (only North Korea is on its unsupported list), but says some cryptocurrencies are unavailable to Korean users. In the US it is a FinCEN-registered money services business with money-transmitter licences in more than 30 states, and in the UK it is registered with the FCA for anti-money-laundering purposes only. It is not registered with Korea's KoFIU. Korean customers are served by its international entity, so local investor protection does not apply. Our advice: to buy with won, use a registered exchange such as Upbit or Bithumb first. Consider an international platform only if you specifically want to buy by card and accept those limits.

07Tax: 22% from 2027?

As of 2026, individuals in South Korea pay no tax on crypto trading gains. The tax was first due in 2022 and has been pushed back several times (to 2023, 2025 and now 2027). Under the Ministry of Economy and Finance's 2026 tax reform proposal of 3 August 2026, from 1 January 2027 gains from transferring or lending virtual assets will count as "other income", and annual gains above ₩2.5 million will be taxed at 22% (20% national plus 2% local).

It is not settled yet. On 23 September 2026 the ruling Democratic Party again called for a delay. It cited gaps in collecting overseas transaction data and missing rules on loss carry-over and acquisition cost, and wants to wait until the Digital Asset Basic Act passes. The final answer usually arrives in December, when the National Assembly votes on the budget and tax bills. Compare other countries in crypto tax in Asia.

08Hacks, fines and scams

Even Korea's biggest exchanges are not risk-free. On 27 November 2025, about ₩44.5 billion of Solana-network assets was stolen from an Upbit hot wallet, with Lazarus suspected. It came exactly six years after Upbit lost 342,000 ETH in 2019. Penalties are frequent too. Dunamu, which runs Upbit, was fined ₩35.2 billion and partly suspended for three months in 2025 over AML and KYC breaches. In March 2026 Bithumb received a record fine of about ₩36 billion and a six-month partial suspension that restricts new customers' external transfers.

On scams, the Financial Supervisory Service keeps warning about "리딩방" (paid stock-tip-style pump rooms), fake exchanges and brokers promising listings for a fee. Upbit runs a dedicated channel for reporting listing fraud. Stay away from any group that promises guaranteed returns. More in exchange safety and licences.

09Wallets and popular coins

Most Korean users keep coins on the exchange. To self-custody, you first need to register your personal wallet with the exchange, because transfers of ₩1 million or more can only go to verified addresses. Popular self-custody wallets include MetaMask (4.77★ in the Korean App Store), Bitget Wallet, OKX Wallet and Trust Wallet, and KAIA users often use Kaia Wallet (formerly Kaikas). For hardware, Ledger is common, and some people use D'CENT, a Korean-made device. See the best crypto wallets for a comparison.

Korean retail traders lean towards altcoins such as XRP and DOGE. XRP is frequently among the top coins by won volume on Upbit, and home-grown tokens like KAIA and BORA have a following. Sharp spikes on new listings (상장 펌핑) are common. This describes the market; we don't recommend specific coins. For contrast with the neighbours, see how to buy bitcoin in Japan.
