New Hampshire Governor Kelly Ayotte signs ‘Blockchain Basic Laws’ – What is HB 639 about?

Governor Kelly Ayotte of New Hampshire has signed HB 639, known as the "Blockchain Basic Laws." The legislation establishes key protections for digital asset ownership and use. It guarantees individuals the right to self-custody their cryptocurrencies in personal wallets and to use them for payments without government interference. The law also shields operators of blockchain infrastructure—such as node operators, miners, and stakers—from being unfairly regulated as money transmitters or securities dealers. Furthermore, it establishes a specialized "Blockchain Dispute Docket" for handling related legal cases efficiently. This bill builds upon New Hampshire's prior move to create a state-level Bitcoin reserve, collectively positioning the state as a leader in fostering blockchain innovation and business.

Navigating the World of Event Trading: Top 5 Prediction Markets for Every Type of User

The prediction market industry has grown significantly, with trading volumes exceeding $20 billion monthly by mid-2026, driven by sports, politics, and macroeconomics. Success now depends heavily on platform choice and execution logistics. This guide compares five leading networks: **Polymarket**: A high-volume, decentralized platform on Polygon, using USDC for international and crypto-native users. It offers diverse markets but lacks built-in risk tools. **Kalshi**: A CFTC-regulated U.S. exchange for institutional traders, using direct fiat. It leads in regulated volume, especially for major sports and economic events, but has limited contract listings. **Outpoll**: A CeDeFi platform for advanced traders, focusing on professional tools. It uniquely features built-in stop-loss/take-profit orders, 0.1% fees, and full API support, with settlement in USDC. **OG Predictive**: A CFTC-regulated, sports-focused platform from Crypto.com. It offers granular player props and a flat fee structure, appealing to long-term position traders. **Manifold Markets**: A play-money, no-KYC platform for casual users and developers. It allows user-generated markets on any topic with zero fees, serving as a sandbox for strategy testing. Key differentiators include regulatory models (regulated vs. decentralized), funding (fiat vs. crypto), order types, risk management features, API access, and mobile support. The conclusion emphasizes that in today's event trading, profitability hinges not just on accurate predictions but on optimizing execution through platform infrastructure, liquidity, fees, and risk tools.

Why Are Large-Scale Crypto Conferences No Longer Glamorous?

Why Are Major Crypto Conferences Losing Their Allure? A growing sense of fatigue surrounds large in-person crypto conferences, with many founders and investors now avoiding events they would never have missed just two years ago. While complaints cite declining ROI and information quality, the root causes are more structural. Crypto, global from inception, once relied on these mega-conferences as neutral hubs for essential face-to-face connections. However, their core value has been fragmented. High-quality participants—developers, investors—have largely migrated to smaller, private side-events, leaving main stages for repetitive content already shared online. The main conference often just becomes the excuse for being in the same city, with attendees scrambling between exclusive dinners and micro-events. While these intimate gatherings offer signal-rich conversations, they lose the "serendipitous encounters" of large conferences and can create insular echo chambers, especially as talent concentrates in hubs like New York. Meanwhile, invite-only, high-caliber summits are rising, offering quality and scale but at the cost of accessibility and crypto's early egalitarian ethos. This shift isn't unique to crypto; AI events in San Francisco show a similar trend. The perception of higher-value interactions drives core groups towards smaller, private settings, potentially creating a vicious cycle that drains larger events of their vitality. Yet, a more optimistic view exists. The apparent decline of crypto-centric events may signal industry maturation. Leading projects are now focused outward—on stablecoins for traditional finance, consumer-facing digital banks, or real-world assets. Crypto topics are increasingly integrated into mainstream finance and tech conferences. Just as dedicated "internet conferences" faded, dedicated crypto summits may become redundant as the technology embeds into every sector. The future likely holds far fewer large, inward-looking crypto conferences. The industry has moved past needing frequent self-congratulatory gatherings. True growth lies in engaging with the broader economy. This evolution towards private networking and mainstream integration, for better or worse, is a mark of the industry coming of age.

Coin & Stock Compass: Global Listed Companies Net Sold $85.45 Million in BTC Last Week, Strategy's Dollar Reserves Scale Up to $3 Billion (July 14)

Global Public Companies Net Sell $85.45 Million in BTC; Strategy's Dollar Reserves Hit $3 Billion (July 14) Last week saw a significant net sell-off of Bitcoin by global public companies, excluding miners, totaling $85.45 million—a 908.42% decrease from the prior week. Major buyers like Strategy (formerly MicroStrategy) and Japan's Metaplanet were notably absent from the market. However, two companies, Brazil's OrangeBTC and asset manager Strive, made purchases, adding 8 and 18 BTC, respectively. The aggregate BTC holdings of tracked public companies now stand at 1,139,635 BTC, valued at approximately $71.38 billion and representing 5.7% of Bitcoin's circulating market cap. In corporate updates, Strategy announced its dollar reserves have grown by $450 million to reach $3 billion, while its BTC holdings remain at 843,775 coins. Hyperscale Data increased its BTC reserves past 1,000 coins. Strategy will report its Q2 2026 financial results on July 30. Mining firm Cleanspark added 454 BTC, bringing its total to 13,924 BTC. Conversely, BitFuFu sold 184 BTC, Bitdeer maintained zero net BTC holdings after selling its weekly production, and Empery Digital sold 1,400 BTC to fund an AI data center project and repay debt. Overall, public companies purchased 110,000 BTC in Q2 2026, 1.8 times the volume of the previous two quarters combined. In other cryptocurrency-related corporate news, Ethereum treasury company Bitmine increased its ETH holdings by 27,801 coins, with total staked ETH exceeding 4.9 million. Solana-focused company DFDV transferred daily operations of its meme coin DONT to an independent team. BNB treasury company BNB Plus was delisted from Nasdaq for failing to meet the $1 minimum bid price and moved to trade on the OTCQB market under the symbol BNBX. The broader equity markets showed mixed signals. Bank of America warned that bullish investor positioning indicated a potential pullback risk for stocks. In contrast, Morgan Stanley predicted the ongoing earnings season could broaden market gains beyond tech giants. Specific regional highlights included continued foreign investor outflows from South Korean stocks, pressure on US equities, and the upcoming IPO of Chinese memory chip maker ChangXin Memory. Most crypto-linked stocks remained in a downtrend.

Tensions Escalate in the Strait of Hormuz, Bitcoin Sells Off as Safe-Haven Asset, Plunging to $61.7K

Bitcoin's price fell sharply on Monday, July 13, dropping approximately 4% to around $61,700, as heightened geopolitical tensions in the Strait of Hormuz triggered a broader shift toward safe-haven assets across global financial markets. Analysts attributed the decline to a confluence of factors: escalating U.S.-Iran tensions fueled risk-off sentiment, reignited inflation concerns, and dampened expectations for near-term Federal Reserve rate cuts. This macro-driven sell-off coincided with a slowdown in institutional ETF inflows and a wave of liquidations for leveraged long positions following Bitcoin's failure to break key resistance levels. Despite the pullback, several market observers characterized the move as a typical, healthy correction within a longer-term bullish cycle, noting that the underlying structural trajectory for Bitcoin remains intact. Attention now turns to upcoming U.S. Consumer Price Index data, which will provide further direction on inflation and monetary policy, key factors influencing risk assets like Bitcoin.

Why Are Major Crypto Conferences Losing Their Luster?

Why Are Major Crypto Conferences Losing Their Appeal? A growing sense of fatigue surrounds large-scale offline crypto conferences. Participants complain of declining returns and less substantial information, but the root cause is deeper. Initially, these global summits were vital for a decentralized industry without a physical hub, enabling crucial face-to-face connections. However, the value of large main-stage events has been eroded. High-quality developers and investors have migrated to exclusive, invitation-only side events and private dinners. While these offer focused networking, they lose the "serendipitous encounters" of larger gatherings and can create elitist barriers, contradicting crypto's open ethos. This fragmentation triggers a vicious cycle: as key people leave main events, their value diminishes further. Simultaneously, the industry's focus is shifting outward. Leading crypto firms are now engaging with traditional finance and real-world applications like stablecoins, digital banking, and prediction markets. Consequently, crypto-specific topics are increasingly integrated into mainstream financial conferences, making dedicated crypto summits potentially redundant. Looking ahead, the frequency of top-tier crypto conferences will likely decrease significantly. The industry has moved past its inward-looking phase. The migration of quality discourse to private settings and the push for mainstream adoption, while diluting the large conference model, are ultimately signs of the sector's maturation.

Trump urges CLARITY Act passage in honor of ‘big supporter’ Lindsey Graham

President Donald Trump is urging the Senate to quickly pass the CLARITY Act, a crypto market structure bill, framing it as a race against China to lead in crypto and AI. He linked the push to honoring the late Senator Lindsey Graham, a key supporter. The bill faces a tight deadline before the Senate's August recess. While gaining support from some law enforcement groups, it faces opposition from banks and Democrats. Banks seek clearer stablecoin rules, and Senator Elizabeth Warren is demanding ethics provisions, citing Trump's past crypto gains. With key Republican absences, Trump needs 9-10 Democratic votes, and Warren's ethics demand could decide the outcome. Market prediction odds for passage have fallen to 38%.

Tensions in the Strait of Hormuz Escalate, Bitcoin Plunges to $61,700 Amid Safe-Haven Selling

Bitcoin fell sharply to around $61,700 on Monday, July 13th, as geopolitical tensions in the Strait of Hormuz triggered a broad shift toward risk-off sentiment across global markets. The decline of roughly 4% mirrored weaker performances in major U.S. stock indices. Market analysts attributed the sell-off to a confluence of factors stemming from the heightened U.S.-Iran tensions. These tensions reignited inflation concerns, reduced expectations for near-term Federal Reserve rate cuts, and prompted investors to reduce exposure to risk assets like Bitcoin. Additional pressure came from slowed institutional ETF inflows, Bitcoin's failure to breach a key resistance level, and a wave of liquidations for leveraged long positions. Despite the drop, analysts largely viewed the move as a typical macro-driven correction within a healthy long-term cycle. They emphasized that Bitcoin's underlying growth trajectory remains intact. The sell-off was seen more as a liquidation event targeting over-leveraged longs rather than a structural loss of confidence. Attention now turns to the upcoming U.S. Consumer Price Index (CPI) report. A higher-than-expected inflation reading could further delay Fed rate cuts, making safer assets like bonds more attractive and continuing to pressure volatile assets like Bitcoin. The consensus is that the current volatility reflects short-term macro and geopolitical shocks, not a fundamental breakdown in Bitcoin's long-term proposition.

Just Now, Musk Admits It: All Code Uploaded by SpaceXAI Deleted

Elon Musk has admitted and confirmed that SpaceXAI's coding assistant, Grok Build, was secretly uploading users' private code and data without consent, and has ordered all such data to be completely deleted. The issue was exposed by an independent security researcher who set up a "honeypot" test repository with fake API keys and passwords. Despite being instructed only to respond "OK" without accessing files, Grok Build proceeded to upload the entire repository's contents and history to a Google Cloud storage bucket. Investigations revealed that the data uploaded was 27,800 times larger than the legitimate task traffic, and the "help improve model" toggle did not stop the collection, only governing whether data was used for training. In one instance, a user's entire home directory was uploaded. The report caused immediate outrage among developers, leading to widespread key rotation and software uninstalls. Following public pressure, SpaceXAI introduced a `/privacy` command for data deletion and, ultimately, Musk pledged to delete all previously uploaded user data with "zero anything whatsoever will remain." The incident has severely damaged trust in AI coding agents, highlighting the inherent risk of granting such tools high-level system access. While the data may be erased, the fundamental concern over privacy and security remains unresolved for developers.
