The White House reaffirmed its commitment to advancing the CLARITY Act in September as Senate lawmakers prepare for a key procedural vote following the August recess. Strategy sold 1,690 Bitcoin for $108.6 million and used the proceeds to repurchase its STRC preferred shares, marking the company’s second consecutive week of Bitcoin sales. Meanwhile, a blockchain executive warned that the first successful quantum attack against cryptocurrency could initially appear as a conventional wallet breach, potentially making the emergence of quantum-powered threats difficult to identify.
White House Pushes CLARITY Act Toward September Vote
The Trump administration remains committed to advancing the CLARITY Act in September despite the Senate’s decision to postpone consideration of the cryptocurrency market structure legislation until after its August recess.
Patrick Witt, executive director of the President’s Council of Advisors for Digital Assets, said the administration would continue negotiating with Democrats “all the way up until the September vote.”
The Senate is expected to hold a cloture vote on the legislation in mid-September. The procedural vote would require 60 senators to support advancing the measure, meaning Republicans will need Democratic backing to move the bill closer to a final vote.
The CLARITY Act would establish a federal regulatory framework for digital assets, including provisions addressing when cryptocurrency tokens fall under securities or commodities laws and how digital asset trading platforms are regulated.
However, disagreements remain over ethics provisions involving Trump-linked cryptocurrency interests and rules concerning rewards for stablecoin holders.
Strategy Sells 1,690 BTC for STRC Buyback
Strategy sold 1,690 Bitcoin for $108.6 million between August 3 and August 9, according to a filing with the US Securities and Exchange Commission.
The company used the proceeds to repurchase approximately 1.15 million shares of STRC, its variable-rate preferred stock, for the same $108.6 million amount.
The transaction represents Strategy’s second consecutive week of Bitcoin sales as the company uses part of its cryptocurrency holdings to support its preferred-stock strategy.
It was also Strategy’s fourth disclosed Bitcoin sale of 2026, bringing total reported Bitcoin sales for the year to 6,948 BTC.
Despite the sales, Strategy continues to hold approximately 840,447 BTC, acquired for an aggregate cost of about $63.36 billion.
STRC is structured as a variable-rate preferred stock with monthly dividend payments, making the buyback part of Strategy’s broader effort to manage its preferred securities and capital structure.
Quantum Threat Could Initially Look Like Ordinary Crypto Theft
The first successful quantum attack against cryptocurrency may not immediately reveal itself as a quantum attack, according to Christopher Smith, CEO and co-founder of blockchain startup Quantus Network.
Smith warned that an attacker with a sufficiently powerful quantum computer could theoretically derive a private key from a publicly exposed blockchain key.
Unlike a conventional cyberattack, such an incident could occur without compromising the victim’s wallet software, hardware or exchange infrastructure.
As a result, investigators could initially see only an unexplained transfer of cryptocurrency from an apparently secure wallet.
Q-Day Remains a Major Security Concern
The hypothetical point at which quantum computers become powerful enough to break modern public-key cryptography is commonly referred to as “Q-day.”
Smith said the difficulty of detecting the first quantum-powered attack could make the transition particularly dangerous for the cryptocurrency industry.
Rather than immediately targeting highly recognizable holdings such as Bitcoin associated with Satoshi Nakamoto, attackers could potentially seek less conspicuous wallets whose movements could initially be attributed to lost keys, conventional hacking or operational mistakes.
The concern comes as advances in quantum algorithms continue to reduce estimates of the computing resources that could eventually be required to attack the elliptic-curve cryptography used by major blockchain networks.
Closing Insights
Today’s crypto developments highlight three different forces shaping the digital asset industry: regulatory policy, corporate Bitcoin treasury management and emerging technological risks. The White House continues to push the CLARITY Act toward a September procedural vote, while Strategy’s latest Bitcoin sale demonstrates how corporate crypto treasuries can be used to manage preferred-stock obligations. At the same time, the potential for quantum attacks adds a longer-term security challenge, particularly because the first successful breach could be difficult to distinguish from an ordinary cryptocurrency theft.
