Charles Hoskinson, the founder of Cardano, stated that Bitcoin's quantum defense proposal BIP-361 has been mischaracterized as a soft fork, and is actually closer to a hard fork, and it cannot protect approximately 1.7 million early BTC generated before 2013, including about 1 million bitcoins attributed to Satoshi Nakamoto.He mentioned that the zero-knowledge proof recovery scheme in the proposal relies on BIP-39 mnemonic phrases, while early wallets used different key generation methods that cannot provide the required proof, thus the relevant assets may be permanently frozen under the current scheme. Reports also indicated that BIP-361 co-author Jameson Lopp described it as a rough concept for an emergency plan, rather than a final specification.

BitMEX co-founder Arthur Hayes stated in his latest article that his fund Maelstrom is currently in a "No Trade Zone," and aside from a slight increase in long positions in Hyperliquid, trading operations have basically ceased in the first quarter.Hayes believes the current market faces two key variables: first, the large-scale proliferation of AI agents will destroy the flexible labor market in the West, leading to a wave of unemployment among knowledge workers and a deflationary financial collapse; second, the war against Iran led by the Trump administration has been ongoing for seven weeks, posing a serious threat to shipping in the Strait of Hormuz.

According to Jinshi reports, the S&P 500 index reached a record high during Wednesday's trading session, marking the first new high since the outbreak of the Iran war. The market's expectations for a de-escalation of the war situation and strong earnings forecasts have attracted investors back to risk assets. Despite the ongoing geopolitical crisis, there has been a shift in market risk pricing, with traders more willing to factor in lower escalation risks in the short term. Since the conflict erupted on February 28, the S&P 500 index had fallen as much as 9%, but did not meet the criteria for confirming a "technical adjustment."

According to CriptoNoticias, an independent security researcher disclosed a prompt injection vulnerability in Coinbase AgentKit, allowing attackers to induce the AI agent to execute unauthorized token transfers through malicious commands, without the need for human confirmation.The vulnerability has been validated through actual transactions on the Base Sepolia test network.

However, the researcher emphasized that the actual impact of the vulnerability is far greater than the official rating.

According to QCP Group, the US-Iran negotiations broke down over the weekend, and oil prices returned above $100, with the market overall shifting towards safe-haven assets. BTC faced resistance at $74,000, while ETH fell from $2,330 to $2,180. Trump subsequently threatened to block the Strait of Hormuz to cut off Iranian oil exports, and Iran retaliated with threats regarding the Strait of Mandeb, further widening the risk exposure.China is at the core of the situation due to its large imports of Iranian crude oil. If a blockade is implemented, the risk of US-China confrontation will significantly increase, and the market has not yet fully priced this in. Nevertheless, the cryptocurrency market has shown strong resilience—implied volatility and risk reversal indicators have both fallen back to pre-conflict levels, indicating a decline in panic sentiment.BlackRock's IBIT saw a net inflow of $612.1 million in the past week, with institutional buying remaining active.
