This week in crypto, Bitcoin developers pushed for greater access to advanced artificial intelligence tools as cybersecurity becomes an increasingly important issue for open-source financial infrastructure. Meanwhile, Strategy reaffirmed its long-term Bitcoin accumulation plans, Australian regulators stepped up action against crypto ATMs, Trezor disclosed a customer data breach, and Samsung revealed plans to bring stablecoins into its mobile wallet ecosystem.
The Bitcoin Policy Institute (BPI), alongside more than 40 organisations across the digital asset industry, has called on leading AI companies to give qualified Bitcoin and open-source developers trusted access to their most capable models.
The group argues that restrictions on publicly available frontier AI systems can prevent legitimate cybersecurity research, leaving developers responsible for protecting major open-source networks without access to the same advanced tools potentially available elsewhere. The letter was backed by organisations including Kraken, BitGo, Bitwise, Blockstream, Ledger, Trezor, MARA and Anchorage Digital.
With Bitcoin securing more than US$1 trillion in value, the industry believes advanced AI could become an important tool for identifying vulnerabilities before they are exploited. The proposal also raises a broader challenge for AI companies: balancing safeguards against malicious use with the need to give trusted security researchers access to powerful defensive tools.
Meanwhile, Strategy has signalled that its recent Bitcoin sales have not changed its long-term accumulation plans. CEO Phong Le said the company expects to resume buying Bitcoin later this year after selling portions of its holdings as its business priorities and capital requirements evolved.
Despite the change in direction, Strategy remains a significant net buyer. Le said the company has purchased approximately 175,000 BTC since the beginning of the year while selling around 7,000 BTC, describing its buying as roughly 25 times greater than its selling. The figures suggest the recent sales represent a shift in treasury management rather than an abandonment of Strategy's broader Bitcoin strategy.
In Australia, AUSTRAC has suspended Cryptolink's registration as a virtual asset service provider for three months, preventing the company from operating its Bitcoin ATM network during the suspension.
AUSTRAC cited ongoing concerns about Cryptolink's ability to manage high-risk transactions, including failures relating to threshold transaction reporting and responding to requests for information. The action continues Australia's broader crackdown on crypto ATMs, which authorities have increasingly targeted over their potential use in scams and money laundering.
Australia has become the largest crypto ATM market in the Asia-Pacific region, making oversight of operators an increasing priority. The Cryptolink suspension demonstrates that AUSTRAC is prepared to restrict businesses that fail to meet their anti-money laundering and reporting obligations.
Security was also in focus after hardware wallet company Trezor disclosed a customer data breach involving third-party shipping provider ShipMonk. Almost 14,000 customers may have been affected, although Trezor confirmed that its own systems and hardware wallets were not compromised.
For 11,742 customers, exposed information may have included names, physical addresses, phone numbers and email addresses. Another 1,947 customers may have had their names, cities and email addresses exposed. The primary risk is now targeted phishing, with scammers potentially able to use the information to impersonate Trezor, banks or cryptocurrency exchanges.
The incident is another reminder that self-custody security extends beyond protecting private keys. Personal information connected to crypto ownership can also be valuable to scammers, making caution around unsolicited emails, calls and requests for wallet information increasingly important.
Meanwhile, Samsung is moving further into digital assets, announcing plans to expand Samsung Wallet beyond traditional payments with support for stablecoins.
Samsung wants to combine payments, rewards and digital assets within a single wallet experience, although the company has not confirmed which stablecoins will be supported or when the functionality will launch. The move builds on Samsung's existing involvement with blockchain technology and digital asset functionality across its devices.
Integrating stablecoins directly into a mainstream mobile wallet could significantly expand their reach. Rather than requiring users to download dedicated crypto applications, blockchain-based payments could eventually sit alongside cards and other everyday financial services already available through smartphones.
This week's developments highlight the growing intersection between crypto, cybersecurity and mainstream technology. AI is emerging as a potentially important defensive tool for Bitcoin, Strategy continues to refine one of the world's largest corporate crypto treasuries, and Australian regulators are tightening oversight of higher-risk services.
At the same time, Trezor's breach demonstrates that security remains an industry-wide challenge, while Samsung's stablecoin plans point towards digital assets becoming increasingly integrated into everyday financial technology. Together, these developments show an industry continuing to mature well beyond trading and market prices.
