Bithumb's Administrative Lawsuit Holds First Hearing, Citing Regulatory Gap for Transfers Under 1 Million Won
According to reports by Korean media outlet Digital Asset, the Second Division of the Seoul Administrative Court held its first hearing on Oct. 22 regarding the administrative lawsuit between Bithumb and Korea's Financial Intelligence Unit (FIU). The FIU found that Bithumb conducted 45,772 transfers with 18 unregistered crypto asset operators between August 28, 2022, and April 3, 2025, and accordingly issued penalties, which included a partial suspension restricting new customers from transferring crypto assets externally for six months. Bithumb stated during the hearing that transfers of 1 million KRW or above are subject to the "travel rule," and since unregistered operators have been removed from the list of eligible exchanges, there were zero non-compliant outbound transfers in that tier. Transfers under 1 million KRW were not covered by the travel rule at the time; thus, the platform had no legal basis to demand that customers provide recipient exchange details, nor did regulators specify clear blocking protocols. Bithumb also noted that after implementing the Chainalysis API, only about 2% of initially unverifiable addresses were later identified as FIU-designated unregistered operators. Enforcing blanket blocks would disrupt the remaining 98% of legitimate transactions, potentially exposing the platform to customer compensation claims. Bithumb further argued that the six-month penalty is excessively severe and practically amounts to banning the platform from acquiring new customers. The company also challenged the FIU's criteria for classifying overseas operators and the grounds for the...

Yoo Young-jun, Director General of the Digital Finance Policy Bureau at South Korea's Financial Services Commission, will attend the meeting.South Korea has postponed the crypto tax three times, most recently pushing the implementation date to 2027. Exchanges say that applicable rules for different transaction types have not yet been determined and that infrastructure preparation time is limited, with the industry broadly supporting a further delay of the tax.South Korean Democratic Party lawmaker Park Min-gyu recently proposed a bill that would set the tax start date as January 1 of the second year after South Korea begins sharing data under the OECD Crypto-Asset Reporting Framework (CARF). If the first data exchange takes place in 2027, the tax would begin in 2029. (Cointelegraph)

At the same time, users should regularly check account login sessions and API key permissions, and be vigilant against scams impersonating customer service.CZ also reminded users that if a platform suffers a data breach, they should promptly change passwords, revoke unnecessary API keys, check withdrawal records, and be alert to phishing attacks carried out using leaked information.

Bonk Guy Calls Another Token USELESS: Already Listed on Upbit and Bithumb, Watch for Its Potential Upside
Trader Bonk Guy (Unipcs) posted that he has long considered USELESS to be this cycle's equivalent to DOGE, SHIB, or PEPE, yet many continue to disregard it. He noted that South Korea's two major centralized exchanges, Upbit and Bithumb, listed USELESS just hours apart today, granting it a major new distribution channel from one of the world's key crypto markets. Bonk Guy further emphasized that attention should remain on whether USELESS will be listed on Hyperliquid, Robinhood, or Binance Spot next. He argued that instead of debating whether USELESS will emerge as this cycle's flagship memecoin, focus should shift to how high its price can potentially reach, as the underlying pattern is becoming increasingly clear. He also noted that investors can either accumulate USELESS now or wait until its market cap reaches several billion dollars, perceiving that stage as "safer".
