What happened: South Korea's dominant crypto exchange, Upbit, expanded trading for four tokens already listed on its Korean won (KRW) market — ETHGas (GWEI), Biconomy (BICO), Bubblemaps (BMT), and Nillion (NIL). By launching eight new BTC and USDT trading pairs, Upbit opened international routes for these assets. The move triggered an immediate reaction across markets: GWEI surged nearly 12% as its 24-hour trading volume jumped almost 200% to $11.1 million, while BICO, BMT, and NIL posted solid gains ranging between 5% and 7.5%.
Why it matters: Adding BTC and USDT pairs is a major structural shift rather than a standard hype-driven listing. KRW-only pairs restrict liquidity to domestic retail traders, but global crypto pairs integrate these assets directly into international order books. This allows market makers and arbitrageurs worldwide to capitalize on price differences between Korean and global venues. The expansion also highlights Upbit's aggressive push to build global trading infrastructure around its ecosystem before South Korea's 22% crypto gains tax takes effect in 2027.
