XCN Now among top 1,000 cryptocurrencies
The surge pushed XCN to its highest level since mid-January, breaking through a multi-month descending channel. By later in the day, the token had settled around $0.0077, representing a 45-53% gain over 24 hours. This occurred against a broader cryptocurrency market that grew 1.01% to a $2.62 trillion market cap, with Bitcoin trading at $77,778, down 0.26%.
The Upbit listing follows a recent surge driven by XCN's addition to Robinhood, which generated a 39% price increase to $0.0069. That event attracted significant whale activity, with Nansen data showing top holders accumulating a net 636.6 million tokens, adding 911 million while selling only 274 million.
Trading volume during the Robinhood listing jumped 219% to $45.53 million, with the Relative Vigor Index (RVGI) showing strong upward momentum at 0.046.
