Over 34% of bitcoin has revealed its public key on chain. What quantum computers could reach, and the two BIPs written to close the gap.
Bitcoin's institutional bull case rested on three supports: steady ETF demand, Strategy's treasury buying, and its digital-gold role. This week the ETFs logged their worst week ever, Strategy fell below the value of its own Bitcoin, and the gold trade unwound. All three broke for the same reason.
Bitcoin closed below $60,000 for the first time since Q3 2024, hitting $58,100 before bouncing. A hot PCE print and $696M in ETF outflows cracked the floor, and derivatives desks are positioned for more.
Bitcoin clung to $62,500 in extreme fear, but the day's real moves were elsewhere: the CLARITY Act hit political risk, Wall Street pushed into prediction markets, and Binance faced a June 30 EU deadline.
In one week, CME sued the CFTC over perps, Oman made its national Bitcoin mining pool mandatory, and China advanced a SWIFT rival. Three layers, one pattern: states and incumbents claiming crypto's rails.
Trump signed the Iran deal and stocks rallied, but crypto fell after Warsh's first Fed meeting signaled fewer cuts. Here is what the dot plot means for Bitcoin's range into Q3.
A US-Iran deal to end hostilities and reopen the Strait of Hormuz sent oil sliding and Bitcoin above $65,500, a two-week high. The catch: it fixes oil, not crypto's demand problem.
The Fed is near-certain to hold on Wednesday, so crypto's real test is the dot plot and Kevin Warsh's first meeting as chair. Bitcoin's bounce off $59K hangs on the tone.
Bitcoin fell under $63K as record ETF outflows, Strategy's first BTC sale in years, a Mt. Gox transfer and geopolitics pulled crypto below $2.5 trillion.
Independent researcher Giancarlo Lelli broke a 15-bit elliptic curve key on publicly accessible quantum hardware, jumping the field forward by a factor of 512.
Bitcoin developers want to freeze $440 billion in dormant coins to protect them from quantum attacks. Critics say the freeze itself would do more damage than any quantum hacker ever could.
A Bitcoin developer wants to fork the chain in August, copy Satoshi Nakamoto's wallet history onto a new network, and hand 500,000 of those coins to people who pay for them now. Jameson Lopp called it outrage marketing. Sztorc says it's a matter of life or death for Bitcoin.
A White House adviser said at Bitcoin 2026 Las Vegas that a major Strategic Bitcoin Reserve update is coming in weeks. The Lummis-Begich bill that would lock the reserve into law just got renamed and reintroduced. Polymarket still gives it a 23% chance before 2027.
BTC is pressing $79K with $630 million in Friday ETF inflows behind it. But liquidity maps are flashing a setup that has burned bulls before.
Patrick Witt told Consensus Miami the executive branch can take a 'big step forward' without waiting for Congress. But the last time Treasury was asked about buying BTC, the answer was no.
