Spark’s native token SPK rallied sharply after Upbit listed the SPK/KRW trading pair, giving the token direct access to South Korea’s won-denominated market on one of the country’s largest crypto exchanges. Reported gains differ across sources: one cited HTX market data showing SPK up nearly 30% to $0.0466 on April 23, while another said the token rose as much as 73%. The move was also linked to more than 500 million SPK being staked, which can reduce liquid supply, and to added speculative attention after F2Pool co-founder Wang Chun said he regretted selling 83.7 million SPK.
