Global cryptocurrency exchange OKX and Korea Investment & Securities are reportedly looking to acquire approximately 20% stakes each in Coinone, a cryptocurrency exchange based in South Korea.

 

To maximize capital flow, the acquisition will involve Coinone issuing new equity shares to OKX and its acquisition partner, rather than selling shares held by existing shareholders. Although the acquisition is, for now, just a financial investment, some industry observers have opined that OKX may become more involved in the exchange’s managerial activities in the future.

 

Currently, The One Group, a private investment company managed by Cha Myung hoon, Coinone’s founder, owns about 34.30% of Coinone, followed by Com2uS Holdings, a South Korean gaming firm, which owns 21.95%, and Com2uS Plus, one of its entities, which owns 16.47 percent. Coinone's CEO, Cha Myung-hoon, owns 19.14%.

 

If successful, this will be the third time a global cryptocurrency exchange has acquired a stake in a South Korean exchange. In 2022, crypto exchange Crypto.com fully acquired OK BIT, a small South Korean crypto exchange, while in 2025, Binance acquired a 67% majority stake in Gopax, one of South Korea’s top five crypto exchanges.

 

Crypto Acquisitions on the Rise

The partial acquisition of Coinone by OKX comes at the same time as Hana Bank, one of South Korea’s largest commercial banks, announced a 6.55% stake acquisition in Dunamu, the parent company of Upbit, the largest cryptocurrency exchange in South Korea.

 

Kraken, through its parent company Payward, has also agreed to acquire Reap, a payments infrastructure firm based in Hong Kong, for about $600 million, just a few weeks after it acquired Bitnomial for $550 million in April.

 

Several other crypto entities have also been involved in acquisitions, including the crypto exchange Bullish, which acquired Equiniti for $4.2 billion, and MoonPay, which recently acquired Dawn Labs.

 

According to a report from Architect Partners, about 89 crypto acquisition deals were completed in the previous quarter, with approximately $3.2 billion spent on crypto-related acquisitions, a significant increase from the first quarter of 2025, which recorded 61 deals and $2.2 billion in deal value.

 

 

KRWQ, a stablecoin pegged to the South Korean won, is expanding to Solana following a recent announcement from IQ, the company behind the stablecoin.

 

The expansion, according to IQ, is aimed at enhancing KRWQ support for various Korean won-denominated trading applications on Solana, including perpetual futures, on-chain foreign exchange markets, arbitrage strategies, cross-margin trading, and other institutional and algorithmic trading systems and applications.

 

 

“The Korean won is a major global currency with substantial activity in offshore derivatives markets, yet it has remained largely inaccessible in crypto native trading systems,” IQ said in a statement to reporters. “KRWQ allows market participants to trade, hedge, and deploy capital using Korean won liquidity directly on chain.”

 

Regarding its decision to launch KRWQ on Solana, the IQ team cited Solana’s low latency and deep liquidity as key reasons for selecting the network.

 

“Solana provides the performance and ecosystem depth needed to scale KRW liquidity on chain,” said Dave Shin, chief operating officer of KRWQ. “We are seeing clear demand for non-USD trading pairs, particularly in derivatives.”

 

As KRWQ’s adoption continues to grow among both retail and institutional users, IQ expects increased usage of the stablecoin across a wide range of applications, including cross-border settlements and advanced trading systems.

 

About the KRWQ stablecoin 

KRWQ is a stablecoin developed by IQ in collaboration with Frax Finance, a notable decentralized finance project. It was created with the main goal of bringing the Korean won (KRW) onto the chain.

 

By enabling 24/7 trading, instant settlement, and low-cost on-chain transactions, KRWQ addresses major inefficiencies in offshore KRW trading, increasing demand for and use of KRW in global payments and decentralized finance, while reducing dependence on US dollar-pegged stablecoins.

 

Since its launch in October 2025, KRWQ has rapidly gained traction as the first on-chain settlement layer for Korean won trading, expanding beyond Base, its initial deployment chain, and going live on Fraxtal, Codex, Morph, and Hydrex. KRWQ was also recently listed on EDX Markets, an institutional-focused cryptocurrency exchange, across spot and perpetual futures.

 

KRWQ now has a spot trading volume of nearly $40 billion and a Non-Deliverable Forward (NDF) market worth about $60 billion.

 

 

KBank, South Korea’s first internet-only bank and the exclusive fiat partner of Upbit, South Korea’s largest crypto exchange, has partnered with Ripple to test its on-chain remittance system.

 

The partnership, according to a local news report, is aimed at leveraging Ripple’s global blockchain infrastructure and network to improve KBank’s international remittance systems, including the speed, cost, and transparency of its services through a proof-of-concept system.

 

 

The proof-of-concept system will test the possibility of KBank moving its cross border remittance system from traditional networks to a faster and cheaper blockchain based system. The process, which has already begun, will involve a two stage verification step.

 

In the first verification stage, which has already been completed, KBank and Ripple examined and verified a wallet app based remittance system. The second stage, which is currently ongoing, will test the stability of the on chain remittance system and will involve the virtual linking of customer accounts to KBank’s internal systems. These accounts will then be used to make on chain transfers to countries such as the United Arab Emirates and Thailand.

 

Although KBank developed its own digital wallet, which was used for the first verification stage, it will leverage Palisade, Ripple’s global SaaS based digital wallet, for the second stage of the proof of concept verification.

 

About KBank 

KBank is South Korea’s first internet only, fully digital bank that operates entirely online without physical branches. It gained prominence in the crypto industry when it became Upbit’s exclusive fiat partner. As a result, every trader who buys or sells crypto on Upbit must move their funds through KBank. In this role, KBank serves as an intermediary between traders and Upbit.

 

Because Upbit is South Korea’s largest cryptocurrency exchange, with a user base of over 13 million, its partnership with KBank had a ripple effect on KBank’s own user base, increasing it from 2 million in 2020 to 15 million by the end of 2025.

 

Apart from its partnership with Upbit, KBank has also been involved in several other crypto related partnerships. Earlier this year, it signed an agreement with UAE based digital asset firm Changer.ae and Korean blockchain company BPMG to build won to dirham stablecoin remittance rails. 

 

KBank has also gone public, completing its initial public offering (IPO) last month, and is now listed on the Korea Composite Stock Price Index, also known as KOSPI.

 

 

The Bank of Korea (BOK), South Korea’s central bank, has proposed the introduction of crypto circuit breakers for domestic cryptocurrency exchanges, months after the Bithumb Bitcoin blunder.

 

In its recently published 2025 Payment and Settlement Systems Report, the bank recommended introducing system-level safeguards similar to the Korea Exchange (KRX) stock market circuit breakers that would automatically halt trading on crypto exchanges, especially during sharp price swings or abnormal transactions caused by large volume or erroneous trades.

 

Referencing the massive payout mishap at Bithumb in February, the BOK argued that this feature would help prevent such incidents from repeating, citing the crypto market’s lack of sufficient safeguards compared to traditional finance. It also suggested including the proposal in South Korea’s pending Digital Asset Basic Act.

 

“The virtual asset industry has inadequate internal control systems and faces weaker regulatory oversight compared to traditional financial institutions,” the bank said.

 

“It is necessary to consider introducing systemic mechanisms such as the Korea Exchange’s circuit breaker, which can block abnormal trades such as large orders or halt trading in the event of sudden fluctuations in virtual asset prices.”

 

Bithumb February Bitcoin Blunder

On February 6, 2026, Bithumb, one of South Korea’s largest cryptocurrency exchanges, was running its routine “Random Box” promotional giveaway. The plan was to distribute small cash prizes totaling 620,000 Korean won (KRW), worth approximately 423 to 460 US dollars, to about 600 qualified users, with each user receiving between 2,000 and 50,000 KRW, or about 1.37 to 34 US dollars.

 

However, the situation escalated when an employee mistakenly entered “BTC” as the currency unit instead of “KRW.” As a result, the system instantly credited approximately 620,000 Bitcoin to users, with each user receiving roughly 2,000 Bitcoin.

 

Bithumb detected the error within minutes and promptly restricted trading and withdrawals on the affected accounts. The exchange was able to recover 99.7 percent of the distributed Bitcoin, while the remaining 1,788 Bitcoin that had already been sold by users were covered by the exchange’s corporate reserves.

 

While the introduction of stock-style circuit breakers for cryptocurrency exchanges appears to be motivated by a desire to protect markets, many experts argue that such measures run counter to the decentralized and borderless nature of cryptocurrency. 

 

Some warn that these guardrails could amplify risks and create price discrepancies between domestic exchanges and global markets. This, in turn, could lead to arbitrage opportunities and confusion, particularly when South Korean exchanges halt trading while the rest of the world continues.

 

 

The Financial Intelligence Unit (FIU), a crime monitoring and prevention body under South Korea’s Financial Services Commission, fined cryptocurrency exchange Bithumb 36 billion won (about $24.5 million) for anti-money laundering (AML) violations.

 

The fine follows an on-site inspection of the exchange conducted by the regulator in March and April last year, which found that Bithumb had violated the Specific Financial Information Act 6.65 million times. The act requires exchanges to restrict transactions with unregistered virtual asset service providers, block suspicious transactions, and verify their customers.

 

Bithumb was also found to have violated the Act on Reporting and Use of Financial Information by facilitating 45,772 cryptocurrency transactions with 18 unregistered overseas virtual asset service providers and cryptocurrency firms. Despite repeated warnings from the regulator, Bithumb failed to take corrective action.

 

"We have continuously requested Bithumb to stop trading with undeclared overseas virtual asset service providers, but it failed to fulfill its legal compliance obligations and demonstrated a markedly insufficient willingness to comply with the law, such as failing to implement effective blocking measures over an extended period," the FIU explained. 

 

In addition to the $24 million fine imposed by the regulator, Bithumb has been ordered to halt all external crypto transfers for new customers from March 27 to Sept. 26. The ban, however, does not affect existing customers trading on the exchange.

 

Despite facing the largest fine ever imposed on a South Korean exchange, Bithumb said it would address the issues highlighted. "We will resolve the issues identified in this inspection and do our best to create a safe trading environment and protect users," the company said.

 

 

South Korea Cracks Down on Compliance Violators

South Korea has been cracking down on compliance violators, particularly cryptocurrency exchanges that breach Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations. In November 2025, the country fined its largest cryptocurrency exchange, Upbit, 35.2 billion won (approximately $25 million) and imposed a three-month partial suspension after the exchange failed to comply with AML and KYC rules.

 

On December 31, 2025, the FIU fined Korbit 2.73 billion won ($1.9 million) and issued a stern institutional warning to the exchange’s executives following a compliance audit that revealed weaknesses in its anti-money laundering (AML) and know-your-customer (KYC) procedures.

 

The FIU is currently conducting an on-site review of Coinone, which is expected to conclude later this year. Although there are unconfirmed reports that the agency has already flagged violations, no official report or penalties have been issued.
