From yesterday to early this morning, Bitcoin and Ethereum experienced rollercoaster movements, with sharp drops followed by rebounds in the early hours. Even seasoned traders were stunned. These intense fluctuations are driven entirely by news and market sentiment.

Bitcoin initially traded sideways between 78,800-79,200, then during the US session, it suddenly broke below 73,000. Now it has recovered above 76,000; Ethereum surged to 2,350 before falling to around 2,110, currently oscillating around 2,260. The sharp decline was triggered by escalating US-Iran tensions causing panic selling, while the rebound in the early hours was due to Trump signing the bill ending the government shutdown, which restored investor confidence and boosted the market.

In terms of trading strategy, keep an eye on key levels: $BTC Bitcoin resistance at 78,000-79,000, with the 80,000 mark as a critical level, and support at 75,000; $ETH Ethereum resistance at 2,450-2,500, with support at 2,100-2,200. The current consolidation hasn't ended yet. News developments combined with key price levels are the main indicators for short-term market direction.
