Bithumb and Korbit Struggle to Gain Traction Despite Zero Trading Fees

Poly Network Exploit Results in Billions of Nonexistent TokensPoly Network, the China-based interoperability platform, was targeted by hackers over the weekend in a major attack that resulted in the creation of billions of tokens out of thin air. It’s the second time in as many years that the cross-chain bridge has been exploited by hackers.The attacker exploited a vulnerability in Poly Network’s cross-chain bridge tool, allowing them to generate a substantial number of tokens that previously did not exist, as reported by Arhat, the Founder of 3z3 Labs, on Twitter.Photo by Shubham Dhage on UnsplashNetwork suspensionThe Shanghai-based project team behind Poly Network promptly informed its users on Sunday that its services were temporarily suspended due to the attack. The platform assured its users that it was diligently assessing the extent of the breach and the impact on assets. They emphasized their commitment to safeguarding users’ assets and urged everyone to remain calm.The hacker, at one point, held nearly $43 billion worth of cryptocurrency in their digital wallet, according to DeBank, a decentralized finance portfolio tracker. This staggering figure was corroborated by PeckShield, a blockchain data and security firm.Bridge vulnerabilitiesBridges play a crucial role in the Web3 ecosystem, enabling users to transfer assets across different networks. However, they have often been attractive targets for hackers. In this attack on Poly Network, the hackers issued themselves nearly 100 million BNB and $10 billion worth of BUSD, the Binance-branded stablecoin, on the layer-2 network Metis, revealed Colin Wu, a Chinese crypto journalist.Similarly, on the Heco network, approximately 100 trillion units of the dog-themed meme coin, Shiba Inu, were created. Additionally, a significant number of altcoins were generated on Polygon and Avalanche networks.Illiquid Metis tokensMetis clarified that the BNB and BUSD tokens issued on its network by the hackers are effectively worthless since there is no available sell liquidity. Poly Network also locked these tokens, ensuring they cannot be utilized. Arhat of 3z3 Labs acknowledged that the impact of the Poly Network attack was somewhat mitigated by the lack of liquidity, which prevented the hackers from realizing substantial gains on Metis.However, on other networks like Ethereum, the stolen tokens were exchanged on decentralized exchanges. Arhat estimated that the attacker managed to convert only a small portion of the tokens, amounting to approximately $400,000 worth of crypto, while the remaining tokens lacked liquidity and were essentially worthless.SlowMist, a blockchain security firm, suggested that the hacker’s total gains were higher. They reported that over $4 million worth of digital assets from the attack had been cashed in, including 1,500 Ethereum worth $3 million and 93 billion SHIB worth $700,000.Poly Network had previously made headlines in 2021 when it experienced a historic attack, considered the largest exploit in decentralized finance at the time. The project suffered a loss of $600 million as funds were siphoned away from Ethereum, Binance Smart Chain, and Polygon. However, the hacker eventually returned $342 million worth of stolen crypto, and Poly Network took steps to repay affected users.

Korean crypto firms relocating for cheaper rent amid prolonged crypto winterAs the prolonged crypto winter continues to affect the industry, blockchain and cryptocurrency firms in South Korea are under pressure to economize. Faced with a deteriorating business and investment climate, numerous companies are reducing their office space and relocating to areas with cheaper rent, according to a Wednesday (local time) report by local media outlet Bizwatch.Photo by Nastuh Abootalebi on UnsplashReducing operating costsBizwatch reported, citing industry sources, that Parameta (previously Iconloop), a blockchain enterprise, has relocated its headquarters from Seoul’s upscale Signature Towers to a more economical shared office space this year. This strategic move is interpreted as an effort to slash operating costs by choosing a location with significantly lower rental expenses. A Parameta representative confirmed that the relocation was part of measures to reduce costs.Binance-backed Streami, which runs the Gopax cryptocurrency exchange, is also reportedly contemplating an office relocation after downsizing its staff. The company’s workforce has dwindled from over 100 employees earlier in the year to approximately 60 by September. A Streami spokesperson has indicated that they have yet to reach a decision regarding the relocation. Streami’s situation is particularly significant due to its ongoing challenges in securing approval from financial regulators for changes to its executive representatives since Binance acquired a majority stake. Recently, Streami appointed a new CEO from the domestic tech firm CityLabs, which has also purchased an 8.55% stake in Streami and intends to further increase its investment in the exchange operator.Similarly, Korea Digital Exchange, the operator of cryptocurrency-only exchange Flybit, has listed for sale one of its two floors of office space in Seoul’s Seocho district. This move comes nearly a year and eight months after the company expanded into the current premises.Changes in workforce sizesBefore the crypto winter, when the Korean crypto market witnessed unprecedented growth, numerous companies expanded their offices to make room for the growing workforce, bolstered by rising revenues. For instance, Dunamu, which runs Upbit — Korea’s largest crypto exchange — garnered attention for acquiring pricey real estate in Gangnam to construct a new office.However, the boom was short-lived. With the onset of the crypto downturn, numerous companies found themselves having to shut down. Blockchain technology firms are facing similar challenges, with many developers steering away from the sector due to persisting market instability. For many of these firms, the workforce has diminished as they’ve either undergone restructuring or struggled to recruit replacements for departing employees.An industry insider remarked that reducing operating costs is a logical step for companies facing a lack of investment and revenue. They noted that this only applies to those resilient enough to weather the hardship, adding that many cryptocurrency-only exchanges are likely to shut down completely in these challenging conditions.In fact, Cashierest, a crypto-only exchange, recently announced the cease of operations. Concerns about the company had been growing after staff layoffs and the departure of its CEO in July. A thorough analysis by the Financial Intelligence Unit (FIU) of the Financial Services Commission (FSC) found that, of the 21 Korean crypto-only exchanges, 18 are operating with negative shareholder equity as of the first half of this year. Moreover, 10 did not earn any revenue from transaction fees during the same period.Crypto-only exchanges typically see lower trading volumes as they cannot facilitate trades in Korean won. In South Korea, only five trading platforms — Upbit, Bithumb, Coinone, Korbit and Gopax — are officially registered with the financial regulator to conduct fiat-to-crypto transactions.

KakaoBank to Conduct Routine Due Diligence on Crypto Exchange CoinoneKakaoBank, one of South Korea’s Internet-only banks, is set to conduct a routine due diligence examination on cryptocurrency exchange Coinone from May 8 to 9, according to crypto media Digital Asset.Photo by Markus Winkler on UnsplashThe mobile bank told Digital Asset that the forthcoming due diligence is unrelated to either the alleged illicit token listings involving former Coinone employees or the exchange’s sole relisting of the WEMIX token in February, which had been delisted from major Korean crypto exchanges due to questionable information about the token’s circulating supply.In Korea, crypto trading platforms supporting Korean won trading are legally obligated to obtain real-name bank accounts from a bank. Last August, KakaoBank signed a one-year contract with Coinone to provide such accounts to the exchange, and the bank will need to decide whether it will extend the contract before August this year.A Coinone official said that the exchange has not undergone any routine due diligence checks from KakaoBank since the contract was signed last year.The upcoming examination is expected to address concerns stemming from rumors that KakaoBank might reconsider its contract with Coinone in light of the bribery scandal that involved two former Coinone personnel and two brokers.
