Uncertainty about the next steps in the Iran war has crypto traders on edge. President Trump has threatened to escalate attacks on Iran if the country doesn’t reopen the Strait of Hormuz, a critical oil transport route, by Tuesday night. However, the president has made this threat repeatedly, extending the deadline as it approaches. Should he proceed with the promised attacks, it would dramatically escalate the war effort — likely creating a headwind for bitcoin and ethereum as investors shift to safer assets.

Ethereum is the blockchain, while ether is the cryptocurrency that runs on it. When people say they’re “buying ethereum,” they’re usually buying ETH — the digital asset used to run applications and store value.
Some investors trade short-term, others accumulate their holdings slowly, and still others focus on earning a yield by locking up their ETH to help run the network — a process known as staking.
Ether, the native cryptocurrency used on the Ethereum platform, remains significantly more volatile than the S&P 500 for many investors. But it’s no longer a moonshot — it’s a foundational piece of a modern digital portfolio.
