South Korean prosecutors have made the first arrests in a major investigation involving "abnormal" foreign exchange transactions and crypto investments, a local media outlet reported on Thursday.

The three people arrested were linked to a remittance platform that transferred 400 billion South Korean won (around $307 million) abroad via a multinational bank in Seoul, the report said.

Allegations against the three include "setting up paper companies and operating a cryptocurrency trading business without registration," Bloomberg reported.

The arrests are part of a larger investigation involving two major local commercial banks Woori and Shinhan, that had transferred $3.4 billion worth of funds overseas, and possible links to "illegal crypto-related activities," Bloomberg reported in late July.

The local media report also said the accused may have tried to take advantage of the "kimchi premium," which is a discrepancy in the price of bitcoin where the cryptocurrency sells for higher rates on South Korean exchanges compared with other global trading platforms.

South Korea is cracking down on the local crypto industry following the collapse of Terraform Labs earlier this year. In July, authorities raided the house of Terra co-founder Daniel Shin, as well as the offices of seven crypto exchanges linked to the firm.

Financial regulators and lawmakers in the country are also planning to expedite the review of new crypto bills, Kim Joo-hyun, the chairman of South Korea's Financial Services Commission, said on Thursday.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.

What to know:

  • Ukraine has no legal framework for Web3 prediction markets, and current legislation provides no recognition for such platforms.
  • Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.
  • Legal changes are unlikely in the near future, as Parliamentary revisions to gambling definitions are extremely improbable during wartime, leaving prediction markets in a legal deadlock.
