Japanese Crypto Exchange Zaif Adds KLAY/JPY and KLAY/BTC Trading PairsJapanese cryptocurrency exchange Zaif added the KLAY token to its list of supported cryptocurrencies on August 16. Following in the footsteps of BITPoint Japan, which introduced KLAY trading in August 2022, Zaif has become the second trading platform in Japan to facilitate the trading of the KLAY token.Zaif’s inclusion of KLAY presents traders with the opportunity to engage with the token using the Japanese yen and Bitcoin (BTC). With this addition, the total number of tokens hosted on Zaif’s platform has now reached 21, bolstering its diverse selection.Photo by Nicholas Cappello on UnsplashKLAY’s path to Green ListKLAY presently requires an additional listing on a Japanese cryptocurrency trading platform to fulfill the requirements for being included in the “Green List” of the Japan Virtual and Crypto Assets Exchange Association (JVCEA). Cryptocurrencies that have achieved green-listed status are exempt from undergoing individualized approval procedures across various exchanges. As stipulated by the JVCEA’s criteria for the Green List, a virtual asset must be featured on a minimum of three member exchanges and exhibit a trading track record of no less than six months on one of these select platforms.As of August 8, the number of green-listed virtual assets is 25, including prominent cryptocurrencies such as BTC, Ether (ETH), and Bitcoin Cash (BCH).Zaif’s upcoming listing of MBXAlong with this development, Zaif is reportedly engaged in discussions with MARBLEX, a blockchain subsidiary belonging to South Korean gaming giant Netmarble. The aim of these talks is to list MBX, the native token of MARBLEX, on the Japanese exchange in October.KLAY is the native token of the Klaytn blockchain, which was created by GroundX, a blockchain-focused arm of Kakao. Kakao is a South Korean tech giant recognized for its widely used messaging app, KakaoTalk. The company has also been expanding its presence in Japan through its subsidiary, Kakao Piccoma, which operates an online comics platform called Piccoma.

Bank of Korea Conducts Successful CBDC Pilot Test with Financial InstitutionsThe Bank of Korea (BOK) announced yesterday in a press release that its central bank digital currency (CBDC) pilot program operated successfully in a practical setting involving multiple financial institutions.Testing environmentsPreviously, the CBDC system was tested in an isolated cloud environment. In this recent test, the system was installed on the servers of various financial institutions over a five-month period to evaluate its performance.The 1.2 billion KRW ($905,000) project included the participation of six companies, such as Kakao’s Krust Universe, KakaoBank, and KakaoPay, as well as 14 banks and the Korea Financial Telecommunications and Clearings Institute. Kookmin, Shinhan, and Woori were among the participating banks.Four scenariosThe BOK and financial institutions tested the system’s performance under four scenarios: increasing transaction requests per second, increasing the number of active users, reducing the transaction queue size, and adjusting the block generation time ratio.The increase in transaction requests led to a 10% decrease in transactions per second (TPS), from 2,100 TPS to 1,900 TPS, compared to the single cloud environment test. This result is still deemed acceptable, as the highest TPS recorded in the current small payment infrastructure network is 1,200, which occurs on paydays and other high-transaction days.Issues such as slower response times arose with higher transaction request volumes but were resolved by enlarging the transaction queue size and increasing the block formation time proportion in the block generation process. The block generation process involves two stages: block formation, where transactions are recorded, and block validation, where transactions are verified.Greater stabilityThe test demonstrated that transaction errors at individual institutions did not affect others, suggesting that a distributed ledger system offers greater management stability than a centralized system. However, institutional officers cited challenges in problem-solving and communication when using the distributed ledger system.The BOK plans to involve more institutions in ongoing experiments this year, supporting them in testing their smart contracts on the CBDC pilot system.Photo by Bundo Kim on Unsplash

The Japanese government and ruling coalition have begun coordinating plans to introduce a flat 20% separate tax on cryptocurrency gains, based on a Dec. 1 report by Nikkei cited by CoinDesk Japan. The change is expected to be reflected in the 2026 tax reform outline.Photo by Nataliya Vaitkevich on PexelsLower crypto taxes, aligned with stocksUnder the proposal, income from crypto trading would be taxed in line with traditional financial instruments such as stocks. This would mark a notable decrease from the current regime, under which cryptocurrency gains are treated in principle as miscellaneous income, combined with salary and other earnings, and taxed on a comprehensive basis at rates that can climb to around 55% including local taxes. Policymakers are reportedly treating the move toward separate taxation as contingent on the establishment of a stronger investor-protection framework through tighter regulation. The planned reforms are also seen as potentially laying the groundwork for the eventual domestic approval of exchange-traded funds (ETFs) backed by crypto assets. Market pullback deepens on policy signalsThe more favorable tax outlook for investors came against a weaker market backdrop. According to CoinMarketCap, the total crypto market capitalization declined about 1.73% over the past 24 hours, extending a pullback that followed recent communications from the central banks of Japan and China. In a Dec. 1 report by Reuters, Bank of Japan (BOJ) Governor Kazuo Ueda indicated that the central bank intended to consider the possibility of an interest-rate increase at its next policy meeting. His comments are interpreted as suggesting a potential shift toward higher rates in December, prompting concern that yen-funded carry trades could begin to be unwound. Such trades typically involve borrowing yen at low interest rates to invest in higher-yielding assets, and their reversal can create pressure on broader asset markets. In a separate weekend statement, the People’s Bank of China (PBOC) restated that digital asset trading remains illegal in China and highlighted what it described as a renewed pickup in speculative crypto activity. The central bank also singled out stablecoins as a source of risk, pointing to concerns about fraud, money laundering, and unauthorized cross-border capital flows that could undermine Beijing’s efforts to maintain capital controls. Against this policy backdrop, major cryptocurrencies moved in mixed directions. Over the past 24 hours, Bitcoin inched up around 1.02%, Ethereum declined about 0.86%, and XRP fell roughly 0.9%. Analysts split amid weak market activityAnalysts and market commentators continued to diverge on the implications of the latest pullback. Veteran trader Peter Brandt suggested on X that Bitcoin may be entering a deeper corrective phase similar to those seen in past bull markets. He cited historical instances of “exponential decay” and suggested the price could retrace toward $50,000 before potentially advancing to the $200,000–$250,000 range in the next rally cycle. Author Robert Kiyosaki, known for “Rich Dad Poor Dad,” reiterated his preference for assets such as gold, silver, Bitcoin, and Ethereum in a Nov. 29 post on X, linking this stance to his view that the Japanese carry trade had effectively run its course. Roughly a week before that message, he had disclosed selling about $2.25 million worth of Bitcoin at around $90,000 per coin, noting that his initial purchase price had been close to $6,000. By contrast, long-time Bitcoin critic Peter Schiff continued to argue in favor of precious metals. He contended that gold derives inherent value from industrial and commercial uses tied to its physical properties, including conductivity, ease of shaping, and resistance to corrosion, while maintaining that Bitcoin lacks practical utility and instead depends on investor belief. SwanDesk CEO Jacob King, another skeptic of the asset, offered an even more pessimistic assessment. He said he did not expect Bitcoin to revisit its previous all-time high and characterized the current decline as the final bear market before the asset ultimately fades from relevance. Shorter-term indicators have reinforced expectations for muted trading conditions. According to CNBC, Grayscale Head of Research Zach Pandl pointed to a decline in open interest for perpetual futures, interpreting it as a sign of reduced speculative positioning and leverage. He also highlighted relatively subdued trading volumes on both centralized and decentralized exchanges, suggesting that near-term market activity is likely to remain restrained.
