South Korea experienced a massive capital flight from its domestic cryptocurrency market in 2025, with investors moving an estimated 160 trillion won (approximately $110 billion) from local exchanges to overseas platforms. This significant outflow was detailed in a joint report by CoinGecko and Tiger Research, highlighting the impact of the country's restrictive regulatory environment.
The primary driver is a stark regulatory gap. Domestic centralized exchanges (CEXs) like Upbit and Bithumb are largely limited to spot trading under current rules, while foreign exchanges such as Binance and Bybit offer Korean investors access to leveraged derivatives and other complex products. This has created a competitive disadvantage for local platforms, pushing traders to seek opportunities abroad.
The regulatory landscape remains uncertain. The long-awaited Digital Asset Basic Act was postponed in December 2025 due to disagreements over stablecoin regulation. Meanwhile, the existing Virtual Asset User Protection Act, effective since 2024, does not cover key areas like derivatives trading. Concurrently, regulators are tightening enforcement, with the Financial Intelligence Unit (FIU) imposing heavy fines for AML violations. Bithumb, the nation's second-largest exchange, faces a potential penalty that could match or exceed the $25 million fine previously levied against Upbit.
Despite the outflows, crypto adoption in South Korea remains robust, with an estimated 10 million people investing—nearly 20% of the population. The report notes that Korean won-based trading volumes often rival U.S. dollar pairs globally. However, the financial impact on foreign exchanges is substantial: estimated 2025 fee income from Korean users reached about ₩2.73 trillion at Binance and ₩1.12 trillion at Bybit, cumulatively totaling ₩4.77 trillion ($3.36 billion) across several major platforms. This sum is 2.7 times the combined operating revenue of South Korea's top five domestic exchanges (Upbit, Bithumb, Coinone, Korbit, GOPAX) in the previous year.
The trend extends beyond centralized platforms. The report also notes growing Korean interest in decentralized perpetual futures exchanges (Perp DEXs), suggesting capital may scatter further into the unregulated decentralized finance (DeFi) space even if access to foreign CEXs is blocked.
