Crypto traders are closely watching developments in the Iran war. While crypto’s non-sovereign nature makes it a logical hedge against geopolitical conflict, the prospect of rising interest rates to stem war-related inflation is a headwind. Both bitcoin and ethereum show gains since the war began, which is not the case for many other assets, including gold and the S&P 500.

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.
