Against the backdrop of an overall market rebound, meme coins are outperforming mainstream cryptocurrencies. Bitcoin rose 0.3%, while Siren surged over 130%, with Solana-based meme coins Bonk and Pepe rising 4.8% and 3% respectively. Analysts believe this rally is related to improved risk appetite, and geopolitical developments, such as the reported easing of US-Iran tensions, may have further boosted risk sentiment. However, the sector remains highly volatile, with fragile market sentiment, and significant pullbacks could occur if market conditions change.
