Most Influential: Sirgoo Lee

Lee shaped the exchange that defines Korea’s crypto market, but even after his exit this year, the country’s hyperactive retail engine will keep moving.

South Korea’s crypto market became one of the busiest trading arenas in the world in 2025, with enthusiastic retail investors powering global surges in XRP, Dogecoin, and many of the memecoins that dominated this cycle.

This feature is a part of CoinDesk's Most Influential 2025 list.

At the center of that liquidity stood Upbit, the exchange that routinely captured more than 80% of the country’s onshore volume and at times moved worldwide prices when a coin listed or spiked. That market was shaped by one executive more than any other: Sirgoo Lee.

When he announced in 2025 that he would step down as CEO, it raised an unusual question for the crypto industry, in South Korea and beyond. Could the world’s most hyperactive retail crypto market operate the same way without the leader who defined its structure and risk culture, or would his exit shift liquidity balances in a country that had become crucial to global price formation?

Part of Lee’s impact came from a management style that stood out in a notoriously hierarchical corporate environment. Inside Dunamu, the parent company of Upbit, he was known for a horizontal approach that encouraged open communication and pushed responsibility downward — a management style common in Western startups but unusual in conservative, strict Korea.

At Upbit, that approach shaped how the company handled user risk. Under his leadership, the exchange built systems that recovered more than 94% of misdirected deposits, established an Investor Protection Center that offers education and legal support, and expanded its compliance and security programs through industry certifications.

In a market where risk-embracing 'degenerate' trading is a point of personal pride, these measures helped Upbit distinguish itself as the venue South Korean investors considered safest.

Upbit’s dominance did not fade as Lee prepared to exit. Its listings still drive significant volume to flavor-of-the-day memecoins, and traffic continues to grow.

Korea’s retail traders will not slow down, and, thanks to Lee, Upbit remains the venue that amplifies their instincts.

New Zealand Dollar declines to near 0.5650 as dovish RBNZ overshadows US tariff relief

New Zealand Dollar declines to near 0.5650 as dovish RBNZ overshadows US tariff relief

The post New Zealand Dollar declines to near 0.5650 as dovish RBNZ overshadows US tariff relief appeared on BitcoinEthereumNews.com. The NZD/USD pair drifts lower to around 0.5655 during the Asian trading hours on Tuesday. The New Zealand Dollar (NZD) softens against the US Dollar (USD) amid an imminent rate cut from the Reserve Bank of New Zealand (RBNZ). Traders await the release of the US September Nonfarm Payrolls (NFP) report later on Thursday.  The RBNZ cut the Official Cash Rate (OCR) to 2.5% at its October meeting after a larger-than-expected 0.9% contraction in Gross Domestic Product (GDP) for the second quarter of 2025. A further reduction of 25 basis points (bps) to 2.25% is widely anticipated at the next meeting on November 26, 2025. The RBNZ has already delivered a series of rate cuts throughout 2025 in an attempt to stimulate a struggling economy.  The prospect of the RBNZ’s aggressive rate-cutting policy overshadowed the US decision to roll back tariffs on Kiwi exports. This, in turn, could exert some selling pressure on the NZD and acts as a tailwind for the pair. In the near term Meanwhile, US President Donald Trump lifted tariffs on more than 200 food products in response to rising US grocery prices. On Sunday, New Zealand welcomed the announcement that it would remove additional tariffs on a range of New Zealand agricultural products, including beef, offal, and kiwi fruit.  Trump removed tariffs on New Zealand exports on more than 200 food products, including beef, amid consumer concerns about rising US grocery prices. It is worth about NZ$2.21 billion ($1.25 billion) annually.  Hawkish remarks from Fed policymakers ahead of a deluge of US economic data spooked traders and could weigh on the USD. Kansas City Fed President Jeffery Schmid said on Friday that monetary policy should lean against demand growth, adding that current Fed policy is “modestly restrictive,” which he believes is appropriate.  New Zealand Dollar FAQs The New…
