According to Eric Balchunas on Twitter, a viral meme about European heatwaves has sparked widespread engagement among crypto traders, highlighting the impact of extreme weather on market sentiment and online trading behavior (source: @EricBalchunas, Twitter, June 13, 2025). While the tweet itself is humorous, the surge in social media activity often correlates with increased volatility in crypto-related discussion and trading volumes, particularly for popular assets such as BTC and ETH. Traders are advised to monitor social sentiment indicators, as heightened meme activity can signal short-term shifts in market mood.
