Bitcoin surged 4% to $71,000 as news of a US-Iran ceasefire improved global market sentiment, triggering renewed investor interest in risk assets. The positive geopolitical development has not only lifted Bitcoin but also fueled gains across the broader cryptocurrency market, including Ethereum.

The easing of tensions between the United States and Iran has reduced immediate geopolitical risks, encouraging investors to move capital back into higher-risk, high-reward assets such as cryptocurrencies. Bitcoin, often seen as both a speculative asset and a hedge, reacted swiftly to the improved outlook.

Ethereum followed Bitcoin's upward momentum, reflecting a broader bullish trend in digital assets. Increased trading volumes and institutional participation have further supported the rally, signaling strong market confidence.

According to insights from CoinMarketCap, the global cryptocurrency market capitalization has seen a notable increase, driven largely by Bitcoin and Ethereum's performance. This highlights how macroeconomic and geopolitical events continue to influence crypto price movements.

Market analysts suggest that while the ceasefire has provided short-term optimism, investors should remain cautious. Factors such as interest rates, regulatory developments, and global economic conditions will continue to play a key role in shaping the crypto market’s trajectory.

In the near term, Bitcoin’s ability to sustain above the $70K level will be closely watched, as it could signal further upside potential if positive sentiment persists.
