Quantum computers need fewer qubits to crack crypto than thought: Google

Google says new research sharply lowers the estimated quantum resources needed to break the elliptic-curve cryptography securing Bitcoin and Ethereum, suggesting fewer than 500,000 physical qubits could solve the key problem—a roughly 20× reduction from prior estimates. In theory, this could enable "on-spend" attacks on Bitcoin within its 10-minute block window, while Ethereum's account model may be more vulnerable to "at-rest" attacks because public keys become permanently visible after a first transaction. Google urges blockchains to begin migrating to post-quantum cryptography now, echoing industry warnings that existing elliptic-curve security may be nearing obsolescence.

Bitcoin price dips below $66K ahead of US Defense Department briefing

Bitcoin briefly spiked above $68,000 but then slipped back below $66,000, trapping late buyers in what analysts described as a classic bull trap. Observers pointed to weak U.S. demand—highlighted by a negative Coinbase Premium—and repeated rejections during U.S. trading hours as reasons for caution. Broader risk sentiment remained tense ahead of a U.S. Defense Department briefing and amid oil staying above $100 on concerns about supply disruptions through the Strait of Hormuz.

Russia moves to narrow crypto trading to regulated intermediaries

Russia's government approved a draft package of crypto bills that would require domestic trading to go through licensed intermediaries and prohibit transactions without regulated middlemen. The framework limits non-qualified retail investors—who must pass a test—to buying only Bank of Russia–designated "most liquid" cryptocurrencies, capped at 300,000 rubles ($3,700) per year via a single intermediary, while allowing broader access for qualified investors. Residents could still buy crypto abroad using foreign accounts if reported to tax authorities, though critics warn the tighter rules may push activity into underground, unregulated channels.

Bitcoin hashrate falls after Iran conflict, HOOD down 16%: Month in charts

Bitcoin ended March roughly flat around $67,000 as five-year US Treasury yields hit a nine-month high near 4%, pushing investors toward cash and away from risk assets amid rising geopolitical tension. After the US and Israel's operation in Iran, Bitcoin's hashrate fell nearly 6%, underscoring Iran's outsized role in mining and how disruptions to energy infrastructure and military priorities can ripple into the network.

Elsewhere in crypto, prediction markets surged to about 192 million transactions in March, up 24% month over month and nearly 2,900% year over year, even as multiple US states moved to restrict or prosecute platforms like Kalshi. Euro-backed stablecoins also gained share, representing about 85% of non-dollar stablecoin volume, while Robinhood shares fell 16% as crypto trading revenue and volumes slid, prompting a $1.5 billion buyback plan; Strategy's Bitcoin holdings sat at an 11% unrealized loss but it kept buying.
