Echobit Observations | 2025 Annual Study on Crypto Regulation and User Structure in South Korea
2026.01.16
Executive Summary
In 2025, South Korea’s crypto market entered a critical phase of structural transition. Rather than a simple cycle of expansion or contraction, the year was defined by regulatory recalibration, shifts in user behavior, and the gradual re-entry of institutional participants under strict compliance frameworks.
Regulators continued to strengthen governance, anti–money laundering (AML), and taxation rules, while selectively opening pathways for corporations and professional investors. At the same time, stablecoin legislation—particularly around KRW-denominated stablecoins—accelerated, signaling a strategic move toward domestic financial sovereignty in digital assets.
From a market perspective, crypto adoption reached unprecedented levels, with the number of crypto investors surpassing stock investors for the first time. However, trading activity declined sharply in the second half of the year, accompanied by significant capital outflows to offshore platforms. This divergence highlights not a loss of interest, but a growing mismatch between user demand and domestic product constraints.
Based on Echobit’s observations, 2025 should be understood as a foundation-building year—one in which compliance clarity, user structure, and infrastructure readiness matter more than short-term volume growth.
1. Regulatory Landscape: From Restriction to Conditional Access
1.1 Opening the Door to Corporate and Professional Investors
In 2025, South Korean regulators approved limited participation by listed companies and professional investors in crypto assets. Under the proposed framework, eligible entities may allocate up to 5% of their paid-in capital to cryptocurrencies ranked within the top 20 by market capitalization.
This marks the most meaningful regulatory shift since the comprehensive tightening of crypto rules in 2021. Detailed implementation guidelines are expected in early 2026.
Implications:
- Capital sources expand beyond retail investors
- Investment behavior shifts toward longer-term allocation and balance-sheet management
- Demand for compliant custody, reporting, and risk controls increases
1.2 Stablecoin Legislation and KRW-Based Digital Currency Strategy
In June 2025, the South Korean government submitted a stablecoin bill to the National Assembly. The draft legislation aims to:
- Establish regulatory standards for stablecoin issuance and reserves
- Encourage the development of KRW-denominated stablecoins
- Reduce systemic reliance on USD-based stablecoins
At a macro level, this aligns with Korea’s broader financial policy goals around currency sovereignty and regulated digital payments, while creating opportunities for compliant blockchain infrastructure and settlement use cases.
1.3 Exchange Governance and Heightened Compliance Requirements
The Financial Services Commission (FSC) proposed a cap on major shareholders’ ownership in large exchanges, suggesting limits of 15–20% to mitigate governance concentration risks. Industry associations publicly opposed the proposal, and final implementation remains pending.
Meanwhile, regulators established a dedicated task force to upgrade the Act on Reporting and Using Specified Financial Transaction Information, with a focus on:
- Higher standards for suspicious transaction reporting (STRs)
- Stronger cross-platform monitoring and Travel Rule enforcement
Overall trend:
2025 did not represent regulatory relaxation, but rather a transition toward more precise participant eligibility under unchanged—or higher—risk control standards.
1.4 Tax Reforms to Reduce Institutional Friction
The Ministry of Economy and Finance announced tax revisions effective in early 2026:
- Crypto inheritance and gift tax valuations will be based on the average market price over one month before and after transfer
- Corporate crypto accounting will shift from FIFO (First-In, First-Out) to a weighted average cost method
These changes significantly reduce accounting complexity and compliance costs, particularly for corporate participants.
2. User Structure and Behavioral Shifts
2.1 Record Adoption, Declining Domestic Trading Activity
By 2025, South Korea’s crypto investor base reached approximately 16.3 million users, accounting for 31.6% of the population—surpassing stock investors (around 14.1 million) for the first time.
However, during the second half of 2025:
- Average daily trading volume on domestic exchanges fell by roughly 80% compared to late 2024
- Approximately KRW 160 trillion flowed to offshore platforms
From Echobit’s perspective, this reflects structural leakage rather than demand contraction, driven by product limitations and regulatory boundaries in the local market.
2.2 Maturing Investment Behavior
Investor behavior became noticeably more conservative and long-term oriented:
- Around 60% of investors hold Bitcoin
- The share of long-term holders increased from 10% to 34%
- High-frequency speculative trading declined
- 66% of users hold portfolios below KRW 500,000 (≈ USD 400)
While retail participation remains dominant, risk tolerance and turnover rates have moderated.
2.3 Youth Dominance and Emerging Institutional Interest
- Users aged 25–34 account for approximately 31% of total users
- This group contributes nearly 80% of trading volume
At the same time, regulatory easing encouraged institutional exploration:
- Banks and asset managers established digital asset task forces
- Focus areas include stablecoins, custody, and compliance infrastructure
Institutional participation remains modest in scale but is characterized by higher regulatory alignment and longer investment horizons.
3. Representative Crypto Asset Trends
3.1 Bitcoin: Core Allocation Asset
Bitcoin remains the dominant asset in Korea:
- Held by roughly 60% of crypto investors
- Acts as the primary driver of market sentiment during bullish cycles
The so-called “Kimchi Premium” persisted throughout 2025:
- Price premiums of 3%–10% compared to global markets
- Reflect local liquidity conditions, capital controls, and demand structure
3.2 Ethereum: Infrastructure-Led Relevance
As stablecoin regulation advanced:
- Ethereum regained attention as a settlement and smart contract layer
- Some exchanges reinstated ETH/KRW trading pairs
- Institutional analysis increasingly focused on Ethereum’s infrastructure role rather than short-term price action
3.3 Local Blockchain Narrative: KAIA
Following the 2024 merger of Klaytn and Finschia, the new chain KAIA continued to strengthen its position in 2025:
- Targeting KRW stablecoin ecosystems
- Integrating with domestic enterprises and Web2 services
After key announcements, KAIA’s token price rose more than 20% in the short term, reflecting market sensitivity to “local compliance + stablecoin infrastructure” narratives.
4. Echobit Observations and Strategic Implications
Echobit’s analysis suggests that South Korea’s crypto market in 2025 entered a low-volatility, high-regulation, structure-driven phase:
- Regulatory focus has shifted from “whether crypto is allowed” to “who may participate and under what conditions”
- With user penetration nearing saturation, competition increasingly centers on product depth and cross-market capability
- Stablecoins and compliant infrastructure are emerging as the key strategic variables for the next cycle
For platforms and service providers, 2025 was not an expansion window but a preparatory phase—laying compliance, governance, and infrastructure foundations for the 2026–2027 market cycle.
