The core statement is that crypto markets declined after Trump warned Iran over reopening the Strait of Hormuz, showing geopolitical tension weighed on digital assets. This is directly stated in 'Crypto market outlook as Trump says Iran’s proposal is “not enough” to avert strikes,' which gives the specific figure of a 2% fall to $2.42 trillion. Al Jazeera independently corroborates the underlying geopolitical trigger: Trump said Iran’s proposal was 'not good enough' and threatened infrastructure strikes unless Tehran reopened the Strait of Hormuz. 'Ethereum price forms double top as market reacts to Iran tensions, will it crash?' further supports that crypto prices weakened in reaction to the same Iran/Hormuz-related comments. The main limitation is that the exact market-cap number and causal phrasing are primarily sourced from crypto.news rather than an independent market data primary source, and the provided X/Odaily links could not be validated in this run.
