South Korean crypto emerges from failed coup into crackdown season

South Korea kicked off 2025 with political chaos, regulatory heat and a crypto market finally brought to heel — or at least forced to grow up.

The nation closed 2024 in disarray following then-President Yoon Suk Yeol’s botched martial law stunt in December.

In the aftermath, authorities spent the first quarter drawing lines in the sand as financial watchdogs slapped cryptocurrency exchanges with probes and lifted the ban on corporate trading accounts. Meanwhile, crypto adoption hit record highs as trading volume cooled.

Here’s a breakdown of the key developments that shaped South Korea’s crypto sector in Q1 of 2025.

South Korean crypto traders given yet another two-year tax exemption

Jan. 1 — Crypto tax postponed

A planned 20% capital gains tax on crypto did not take effect on Jan. 1 after lawmakers agreed to delay it until 2027. This was the third postponement: first from 2022 to 2023, then again to 2025.

The latest delay, reached through bipartisan consensus in late 2024, came amid mounting economic uncertainty and political turmoil. Lawmakers cited fears of investor flight to offshore exchanges, challenges in tracking wallet-based profits, and shifting national priorities in the wake of Yoon’s failed martial law stunt and subsequent impeachment.

Jan. 14 — Warning against North Korean crypto hackers

The US, Japan and South Korea published a joint statement on North Korean crypto hacks. Crypto firms were warned to guard against malware and fake IT freelancers. Lazarus Group, the state-sponsored cyber threat group, was named as a prime suspect in some of the top hacks in 2024, such as the $230-million hack on India’s WazirX and the $50-million hack against Upbit, South Korea’s largest crypto exchange.

Jan. 15 — Companies wait on the sidelines for crypto greenlight

South Korea’s Virtual Asset Committee, a crypto policy coordination body under the Financial Services Commission (FSC), held its second meeting. The FSC was widely expected to approve corporate access to trading accounts on local exchanges. Despite popular demand, the FSC held off on making an official decision, citing the need for further review.

Instead, the FSC announced investor protections against price manipulation and stricter stablecoin oversight.

Jan. 16 — First enforcement of crypto market manipulation

South Korean authorities indicted a trader in the first pump-and-dump prosecution under the Virtual Asset User Protection Act, the new crypto law effective from July 2024.

Meanwhile, Upbit received a suspension notice for allegedly violating Know Your Customer (KYC) requirements in over 500,000 instances, prompting regulators to consider a ban on new user registrations.

Jan. 23 — Upbit, Bithumb compensate users after service outages during martial law

Upbit and rival exchange Bithumb announced plans to compensate users following service disruptions triggered by the surprise declaration of nationwide martial law on Dec. 3, 2024. The shocking move caused panic across financial and crypto markets, leading to a surge in traffic that overwhelmed local trading platforms.

South Korean crypto world finally opened to corporations

Feb. 13 — Charities and universities get first dibs on corporate crypto access

The FSC unveiled its long-awaited plan to allow corporate entities to open crypto trading accounts in phases by late 2025. The rollout will require businesses to use “real-name” accounts and comply with KYC and Anti-Money Laundering (AML) regulations. Charities and universities are first in line and will be allowed to sell their crypto donations starting in the first half of the year.

South Korea’s real-name financial transaction system, introduced in 1993, was designed to combat tax evasion and money laundering by requiring all bank accounts to be opened under verified legal names using national IDs.

Crypto trading exploded in 2017, driven in part by anonymous accounts from businesses, foreigners and minors. Financial authorities responded by requiring crypto exchanges to partner with domestic banks and offer fiat services only through verified real-name accounts. To date, only five exchanges have met the requirements.

Since there was no regulatory framework for real-name corporate accounts, this policy effectively shut out both overseas users and domestic companies from trading on South Korean exchanges. The new roadmap aims to fix that by creating a formal structure for institutional participation under tighter compliance standards.

Feb. 21 — Alleged serial fraudster busted again

Police rearrested “Jon Bur Kim,” identified by the surname Park, for allegedly profiting 68 billion won (approximately $48 million) in a crypto scam involving the token Artube (ATT). He allegedly employed false advertising, pump-and-dump tactics and wash trading to manipulate the market.

This wasn’t Park’s first brush with the law. He was previously indicted in a 14-billion-won (around $10 million) token fraud case and was out on bail when he launched ATT.

Feb. 25 — Upbit operator Dunamu gets slapped

The nation’s Financial Intelligence Unit (FIU) formally notified Dunamu, operator of Upbit, of regulatory action. The sanctions were tied to KYC compliance failures and dealings with unregistered foreign exchanges. The FIU issued a partial business suspension, restricting Upbit from processing new customers’ deposits and withdrawals for three months.

Feb. 27 — Crypto crime force formalized

South Korean prosecutors formally launched the Virtual Asset Crime Joint Investigation Division, following a year and seven months as a temporary operation. As a non-permanent unit from July 2023, the task force indicted 74 individuals, secured 25 arrests, and recovered over 700 billion won (around $490 million) in illicit gains. The 30-person task force includes prosecutors, regulatory staff and specialists.

Feb. 28 — Upbit operator Dunamu files lawsuit to overturn business sanctions

Dunamu said it filed a lawsuit against the FIU to challenge the sanctions imposed on the exchange.

Bitcoin ETF next on checklist for South Korean crypto space

March 5 — Reconsidering Bitcoin ETF ban

The FSC started reviewing legal pathways to allow Bitcoin (BTC) spot exchange-traded funds (ETFs), citing Japan’s evolving regulatory approach as a potential model. This marks a notable shift from South Korea’s previous opposition to crypto-based ETFs.

The Capital Markets Act does not recognize cryptocurrencies as eligible underlying assets for ETFs. However, in 2024, lobbying efforts from major domestic brokerages intensified amid rising client demand, especially after spot Bitcoin ETFs were approved in the US.

While the review remains in its early stages, regulators are no longer dismissing the possibility outright.

March 21 — Crackdown on unregistered exchanges begins

The FIU compiled a list of illegal foreign exchanges and moved to block access via app stores and ISPs. Additionally, the agency warned of criminal penalties for trading platforms operating without a license.

March 26 — 17 exchange apps blocked (including KuCoin and MEXC)

Google Play removed 17 unlicensed crypto exchange apps in South Korea at the request of regulators. The FIU said it is also working with Apple to block unauthorized crypto platforms.

March 27 — Upbit scores three-month break

A South Korean court temporarily lifted the Feb. 25 partial business suspension imposed on crypto exchange Upbit by the FIU. The court’s decision allows Upbit to resume serving new users while the case is under review.

South Korean crypto expected to go from crackdown in Q1 to campaign trail in Q2

As March ended, more than 16 million investors — roughly a third of South Korea’s population — held crypto accounts, surpassing the 14.1 million domestic stock traders. But that surge in adoption came as trading activity cooled. Upbit, the country’s dominant exchange, saw volumes fall by 34%, dropping from $561.9 billion in Q4 2024 to $371 billion in Q1 2025, according to CoinGecko.

By mid-April, the crackdown was still gaining steam. Apple followed Google’s lead in removing offshore exchange apps from its store, while prosecutors filed yet another round of market manipulation charges.

South Korea’s crypto industry is now contending with tighter rules, rising institutional expectations and a government no longer content to watch from the sidelines.

All this unfolds ahead of an early presidential election in June, following Yoon’s impeachment. Crypto played a visible role in Yoon’s successful 2022 presidential election campaign and is expected to remain a key issue with voters. 

One candidate in the upcoming election, former prosecutor Hong Joon-pyo of the People Power Party, recently pledged to overhaul crypto regulations in line with the pro-industry stance of the Trump administration, local media reported. Despite the pledge, Hong’s understanding of the technology came into question as he admitted to not knowing what a central bank digital currency is.

Growing BTC reserve requires Congressional legislation — VanEck exec  

Building a permanent US strategic Bitcoin reserve would likely require targeted legislation rather than executive action, according to VanEck’s head of digital assets, Matthew Sigel. Speaking at Bitcoin 2025 in Las Vegas, Sigel said the most viable path forward may involve inserting Bitcoin mining incentives into the congressional budget reconciliation process.According to Sigel, the most effective path to growing a US strategic Bitcoin reserve would be through targeted amendments to congressional budget legislation. These could include tax credits for mining companies that use methane gas and other incentives aimed at encouraging miners to share a portion of their mined BTC with the federal government. He argued that such an approach would allow the reserve to grow organically over time. Sigel also highlighted the limitations of executive actions in achieving this goal:”The problem with executive action is that it’s going to prompt lawsuits. And anything over $100 million is going to get sued by the Elizabeth Warrens of the world. So, I would say start with something maybe in the Exchange Stabilization Fund for $100 million.”US President Donald Trump established the US Bitcoin Strategic Reserve through a March 7 executive order. According to the order, the US government can only acquire Bitcoin through budget-neutral strategies or asset forfeiture, prompting a range of different ideas on how to add to the government’s stockpile of nearly 200,000 BTC.From left to right, Alex Thorn, Matthew Sigel, Matthew Pines and Fred Thiel.

ZKPs can prove I'm old enough without telling you my age  
ZKPs can prove I'm old enough without telling you my age  

Opinion by: Andre Omietanski, General Counsel, and Amal Ibraymi, Legal Counsel at Aztec LabsWhat if you could prove you’re over 18, without revealing your birthday, name, or anything else at all? Zero-knowledge proofs (ZKPs) make this hypothetical a reality and solve one of the key challenges online: verifying age without sacrificing privacy. The need for better age verification todayWe’re witnessing an uptick in laws being proposed restricting minors’ access to social media and the internet, including in Australia, Florida, and China. To protect minors from inappropriate adult content, platform owners and governments often walk a tightrope between inaction and overreach. For example, the state of Louisiana in the US recently enacted a law meant to block minors from viewing porn. Sites required users to upload an ID before viewing content. The Free Speech Coalition challenged the law as unconstitutional, making the case that it infringed on First Amendment rights. The lawsuit was eventually dismissed on procedural grounds. The reaction, however, highlights the dilemma facing policymakers and platforms: how to block minors without violating adults’ rights or creating new privacy risks.Traditional age verification failsCurrent age verification tools are either ineffective or invasive. Self-declaration is meaningless, since users can simply lie about their age. ID-based verification is overly invasive. No one should be required to upload their most sensitive documents, putting themselves at risk of data breaches and identity theft. Biometric solutions like fingerprints and face scans are convenient for users but raise important ethical, privacy, and security concerns. Biometric systems are not always accurate and may generate false positives and negatives. The irreversible nature of the data, which can’t be changed like a regular password can, is also less than ideal. Other methods, like behavioral tracking and AI-driven verification of browser patterns, are also problematic, using machine learning to analyze user interactions and identify patterns and anomalies, raising concerns of a surveillance culture.ZKPs as the privacy-preserving solutionZero-knowledge proofs present a compelling solution. Like a government ID provider, a trusted entity verifies the user’s age and generates a cryptographic proof confirming they are over the required age. Websites only need to check the proof, not the excess personal data, ensuring privacy while keeping minors at the gates. No centralized data storage is required, alleviating the burden on platforms such as Google, Meta, and WhatsApp and eliminating the risk of data breaches. Recent: How zero-knowledge proofs can make AI fairerAdopting and enforcing ZKPs at scaleZKPs aren’t a silver bullet. They can be complex to implement. The notion of “don’t trust, verify,” proven by indisputable mathematics, may cause some regulatory skepticism. Policymakers may hesitate to trust cryptographic proofs over visible ID verification. There are occasions when companies may need to disclose personal information to authorities, such as during an investigation into financial crimes or government inquiries. This would challenge ZKPs, whose very intention is for platforms not to hold this data in the first place.ZKPs also struggle with scalability and performance, being somewhat computationally intensive and tricky to program. Efficient implementation techniques are being explored, and breakthroughs, such as the Noir programming language, are making ZKPs more accessible to developers, driving the adoption of secure, privacy-first solutions. A safer, smarter future for age verificationGoogle’s move to adopt ZKPs for age verification is a promising signal that mainstream platforms are beginning to embrace privacy-preserving technologies. But to fully realize the potential of ZKPs, we need more than isolated solutions locked into proprietary ecosystems. Crypto-native wallets can go further. Open-source and permissionless blockchain-based systems offer interoperability, composability, and programmable identity. With a single proof, users can access a range of services across the open web — no need to start from scratch every time, or trust a single provider (Google) with their credentials.ZKPs flip the script on online identity — proving what matters, without exposing anything else. They protect user privacy, help platforms stay compliant, and block minors from restricted content, all without creating new honeypots of sensitive data.Google’s adoption of ZKPs shows mainstream momentum is building. But to truly transform digital identity, we must embrace crypto-native, decentralized systems that give users control over what they share and who they are online.In an era defined by surveillance, ZKPs offer a better path forward — one that’s secure, private, and built for the future.Opinion by: Andre Omietanski, General Counsel, and Amal Ibraymi, Legal Counsel at Aztec Labs.This article is for general information purposes and is not intended to be and should not be taken as legal or investment advice.
