South Korea’s largest cryptocurrency exchange continues to list smaller altcoins, a move that frequently triggers immediate and substantial price spikes — sometimes double- or triple-digit gains, as shown by today’s example.
Upbit announced hours ago that it will list Base (B3) in a trading pair against the Korean won, according to blockchain journalist Wu Blockchain.

B3’s price reacted almost immediately, surging more than 300% from its low to its intraday high. Earlier today the token traded around $0.0005 before the announcement spread on social media; it then jumped to approximately $0.0022. The price has since pulled back to about $0.0016, which still represents roughly a 280% increase over the past 24 hours.
Base (B3) is a layer-3 settlement chain built atop the Base network, which is associated with Coinbase. The project aims to enhance on-chain gaming and consumer applications through its Open Gaming ecosystem.
B3 emphasizes sub-cent transaction fees and high throughput, features intended to make blockchain gaming more accessible and scalable for mainstream users and developers.
Historically, Upbit listings have tended to produce immediate price pumps for the assets involved, including larger-cap cryptocurrencies. For example, in March the Internet Computer (ICP) jumped roughly 16% within minutes after Upbit announced its listing.
Similarly, ETHFI rose about 18% following its Upbit listing, while smaller altcoins such as POKT and LPT experienced dramatic moves — with one climbing roughly 350% and the other about 80% after being listed on the exchange.
