Trump's Iran ultimatum and ceasefire hopes sparked market volatility alongside Circle's quantum-resistant roadmap and Saylor's BTC buy while BTC tapped $69,500 amid extreme fear. Bitcoin (BTC) and Ether (ETH) showed different market structures and capital sentiment over the past 24 hours. BTC is now trading around $69,164.6. As political instability in the US collided with rising geopolitical risk in the Middle East, safe-haven demand helped push total Bitcoin futures open interest up 5.05% across the market to USD 49.512 billion. Short liquidations also reached USD 104 million over the same period. However, Santiment data showed BTC’s profit-to-loss transaction ratio climbed to 2.95, its highest level in 12 weeks. From a technical perspective, that is often seen as a warning sign of a short-term local top. At the same time, the Ethereum market is facing heavier selling pressure and weaker confidence. Total ETH futures open interest edged up slightly to USD 28.469 billion, but the options market showed a sharp increase in upside call selling. This suggests traders are shifting toward earning premium income instead of positioning for a directional rally. If ETH breaks below the key $2,024 support level, major exchanges could face as much as USD 916 million in long liquidations. The Crypto Fear & Greed Index currently stands at just 14, which signals Extreme Fear. In the absence of a clear bullish catalyst, overall market sentiment remains cautious and highly watchful.

Key News Highlights:

Trump’s Final Warning to Iran Shakes Markets While Ceasefire Hopes Still Linger

US President Donald Trump recently issued highly aggressive remarks over Iran’s closure of the Strait of Hormuz, warning that if Iran does not reopen the waterway, it will be made to “live in hell.” The statement sent shockwaves through global financial markets. According to his latest Truth Social post, Trump set a deadline for this Tuesday and warned that Iran’s power plants and bridges could become targets, pushing oil prices up to $112 a barrel and adding to global inflation pressure. At the same time, markets also picked up a possible opening for de-escalation. In a later interview, Trump said talks were underway and said he was optimistic that an agreement could be reached within 24 hours. Driven by these mixed signals, total crypto market capitalization rose by about USD 70 billion in early Monday trading and reached USD 2.44 trillion, the highest level in 11 days, while Bitcoin briefly touched $69,500. Meanwhile, reports said the US and regional mediators were discussing a 45-day ceasefire proposal. This violent swing between geopolitical threat and peace expectations triggered about USD 255 million in liquidations across the crypto market over 24 hours, with shorts accounting for 73%, showing that sensitivity to macro uncertainty has reached an extreme level.

Circle Unveils a Quantum-Resistant Security Roadmap for Its Layer-1 Blockchain Arc

Stablecoin issuer Circle has officially released a post-quantum security roadmap for its Layer-1 blockchain Arc, aiming to address the growing threat of Q-Day. As researchers from Google and the California Institute of Technology warned that quantum computers may be able to break existing cryptographic systems within a relatively short timeframe, Circle said it will adopt a phased rollout plan. The first step is to offer optional quantum-resistant wallets and signing features when Arc mainnet launches. Circle stressed that quantum resilience must move beyond theory and into real infrastructure, because once quantum machines reach sufficient computing power, active addresses with exposed public keys could face serious risk. The roadmap also includes the introduction of quantum privacy solutions after mainnet launch to protect transaction data and financial information. In later stages, the defense framework will be extended to validator nodes and off-chain infrastructure. The blockchain industry still remains divided on how urgent the quantum threat really is. Even so, while projects such as Algorand and Ethereum are actively exploring relevant solutions, Circle’s move shows that major financial infrastructure providers have already started to treat Q-Day preparedness as a core technical standard in order to preserve the resilience of assets such as USDC during periods of extreme technological change.

Michael Saylor Signals Strategy May Resume Bitcoin Accumulation After a One-Week Pause

After an unusual one-week break at the end of March, Michael Saylor recently posted “Back to Work” on social media alongside his company’s Bitcoin tracker chart, signaling that the institution with one of the largest corporate Bitcoin reserves may soon restart its weekly accumulation program. The company had previously completed a USD 77 million purchase on March 23, then paused what had been an uninterrupted buying streak this year. Based on market data analysis, the firm has mainly been raising capital through sales of its perpetual preferred stock STRC, and the funds raised last week are estimated to be enough to support the purchase of at least 1,821 BTC. Although the company’s current holdings of 762,099 BTC carry an average acquisition cost of about $75,694 per coin, leaving the position under water on paper, that has not weakened its long-term strategy. The company also recently announced a financing plan worth as much as USD 44.1 billion, showing that even amid macro volatility and short-term weakness in Bitcoin prices, it continues to pursue an extremely aggressive treasury expansion strategy and is still using long-term Bitcoin holdings as a hedge against inflation risk in the fiat system.
