Bitcoin has fallen nearly 50% from its July 2025 record above $123,000, and was trading around $63,900 as of Friday. The pullback, alongside declines of roughly 4% in the Nasdaq Composite and 8% in gold, is pushing investors to reconsider whether bitcoin belongs in a diversified portfolio and, if so, what a prudent allocation looks like.

Bitcoin (BTC) moved back above $64,000 on June 12, trading near $64,300 and rising about 1.9% over 24 hours. Analysts said the $64,000–$65,000 band remains the key resistance zone, with a break above $65,000 seen as important for a stronger rebound. Several major altcoins also posted gains during the session, alongside improving broader risk sentiment.

SpaceX said it completed a $75 billion IPO on June 12 while holding Bitcoin on its balance sheet. The company disclosed 18,712 BTC worth about $1.19 billion at press time, and reported an unrealized gain of $431 million. As shares began trading on Friday, BTC briefly reached around $64,300 before trading near $64,720, up 1.57% over 24 hours.

BlackRock filed a Form 8-A with the SEC on June 11 for its iShares Bitcoin Premium Income ETF (BITA), registering shares for listing on Nasdaq. Bloomberg ETF analyst Eric Balchunas said the step typically indicates trading could begin in about a week, pointing to a potential June 18 launch. BTC was priced at $63,476.23 at press time, up 1% over 24 hours and 2.5% over seven days.

Last month, the U.S. Commerce Department signed letters of intent to award just over $2 billion to nine quantum computing firms, including $1B for IBM and $375M for GlobalFoundries. The author argues this accelerates the race toward a cryptographically relevant quantum computer, while post-quantum defenses for Bitcoin and other systems remain slowed by coordination and adoption barriers. NIST timelines cited in the piece deprecate RSA-2048 and ECDSA at 112-bit security in 2030 and disallow them in 2035, raising pressure for industry-wide migration planning.

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.
