Coinbase's Quantum Advisory Council says Bitcoin and other crypto networks should start preparing for a post-quantum transition ahead of any practical quantum attack. The group estimates roughly 7 million BTC could be exposed due to visible public keys or address reuse, including about 1.7 million BTC held in legacy Pay-to-Public-Key addresses.

Iran said on June 11 the Strait of Hormuz remained closed, even as President Donald Trump claimed the U.S. had reached a "great deal" with Tehran. Bitcoin traded around $63,400 on June 11 after dropping to $60,914, as markets weighed de-escalation hopes against ongoing disruption in a route that carries about 20% of global energy.

SpaceX is scheduled to start trading on Nasdaq on June 12, 2026, after a $75 billion IPO, and market participants are weighing how the listing could affect crypto sentiment. One view is that more than $5 billion of outflows from bitcoin ETFs helped push BTC below $60,000 as investors sought IPO liquidity, which could later rotate back into crypto. Others warn that record IPOs have often appeared near equity-market peaks, potentially pressuring risk assets, including bitcoin, which has hovered around $63,000 after briefly dipping under $60,000 last week.

Bitcoin has slid nearly 15% since Strategy disclosed on June 1 that it sold 32 BTC between May 26 and May 31 for about $2.5 million, while MSTR shares fell 24% over the same span. Speaking at BTC Prague, chairman Michael Saylor said he tells individuals not to sell Bitcoin but never promised the company would not, adding Strategy has long disclosed it may sell if needed.

JPMorgan says the macro "debasement trade" that previously pushed billions into Bitcoin and gold is unwinding, with the retreat accelerating for BTC. Bitcoin is trading above $63,000 after falling from an October peak above $126,000, while gold ETFs shed $20 billion in the week through June 5 and US spot bitcoin ETFs logged $2.1 billion of outflows in June. A Sygnum CIO argued the flows may reflect cash-and-carry arbitrage being closed rather than broad capitulation.

At the BTC Prague conference on June 11, Strategy founder Michael Saylor said he "never said the company could not sell bitcoin," framing "never sell" as guidance aimed at individuals rather than a corporate promise. The comments followed Strategy's June 1 sale of 32 BTC for about $2.5 million to help fund preferred-stock dividends, a first-ever disposal that unsettled some holders.

Bitcoin climbed from $61,100 to above $63,400 on June 11, a roughly 3% move tied to risk-on sentiment after President Trump said the U.S. stepped back from planned Iran strikes and a peace memo could be signed as early as this weekend. The rally came while spot Bitcoin ETFs logged 13 straight sessions of outflows totaling $4.4 billion, with markets also focused on the Federal Reserve's June 16–17 meeting and a 98% probability of a rate hold.

BlackRock moved closer to launching its iShares Bitcoin Premium Income ETF (ticker: BITA) after filing Form 8-A with the SEC on June 11. The prospectus lists a 0.65% sponsor fee and a seed portfolio that includes 109.96 BTC and 90,901 IBIT shares, with the strategy designed to sell covered calls to seek monthly income. A Bloomberg ETF analyst said the filing often precedes a launch within about a week, placing June 18 as a possible start date, though not guaranteed.
