Blockchain and Web3 Weekly Insights: Market Trends, ETF Flows, and On-Chain Developments

·

The blockchain and Web3 landscape continues to evolve at a rapid pace, with significant developments across decentralized finance (DeFi), exchange-traded funds (ETFs), on-chain activity, and infrastructure security. This week saw notable shifts in market dynamics, including declining centralized exchange volumes, record-breaking decentralized exchange activity, and major movements in Bitcoin supply distribution. Below is a comprehensive breakdown of the latest trends shaping the crypto ecosystem.

Bitcoin ETF Outflows Signal Market Consolidation

On July 2, data from Farside Investors revealed that U.S. spot Bitcoin ETFs experienced a net outflow of **$342.2 million**. This marks a significant moment in investor sentiment, particularly as major players like IBIT reported zero net movement, while FBTC saw outflows of $172.7 million and GBTC shed $119.5 million.

These outflows suggest a period of consolidation following earlier bullish momentum. Analysts believe this trend reflects strategic rebalancing rather than a loss of confidence, especially given the simultaneous decline in exchange-based Bitcoin supply.

Exchange Bitcoin Supply Hits 7-Year Low

In a bullish signal for long-term holders, the percentage of Bitcoin supply held on exchanges has dropped to 14.5%, the lowest level since August 2018, according to Glassnode data cited by Cointelegraph.

This decline indicates that more investors are moving their BTC off exchanges and into self-custody or cold storage — a behavior historically associated with accumulating phases. With fewer coins available for immediate sale, market volatility may decrease over time, potentially setting the stage for future price appreciation.

DEX Trading Volume Reaches Record High

While centralized exchange (CEX) spot trading volume fell to $1.07 trillion in June — its lowest level in nine months — decentralized exchanges (DEXs) hit an all-time high of **$390 billion** in monthly trading volume.

This divergence underscores a growing preference for non-custodial trading platforms, driven by improved user experience, lower counterparty risk, and increasing trustlessness in financial infrastructure. Presto Research analyst Min Jung attributes this shift to institutional-led Bitcoin accumulation, which tends to favor secure, transparent environments over traditional custodial models.

Binance Alpha Sees Strong Daily Volume

Despite broader CEX slowdowns, Binance’s innovation-focused platform Binance Alpha reported a daily trading volume of **$439.6 million** on July 1. Leading assets included BR (with $307.29 million in volume), KOGE ($31.42 million), and BULLA ($18.14 million).

This sustained interest highlights ongoing demand for early-stage projects and community-driven listings, even amid macro-level market caution.

xStocks Platform Gains Traction with Tokenized Stocks

Backed’s stock tokenization platform xStocks recorded $5.82 million in trading volume on its second day — a more than fourfold increase from its debut day’s $1.34 million. The platform also attracted 5,641 daily active users and processed over 15,700 transactions.

Top-performing assets included tokenized versions of the S&P 500 index (with $1.69 million in volume), Tesla, and Circle stock tokens. This rapid adoption signals strong retail interest in fractionalized, blockchain-based access to traditional financial instruments.

Security Alert: Chrome V8 Zero-Day Exploit

Users are urged to update their browsers following disclosure of a critical zero-day vulnerability in the Chrome V8 JavaScript engine (CVE-2025-6554). According to SlowMist CISO @im23pds, attackers can exploit this flaw to run malicious code via crafted web pages.

With proof-of-concept (PoC) exploits already public and actively used, crypto users face increased risk of phishing attacks leading to asset theft. Immediate mitigation includes updating Chrome to the latest version and avoiding suspicious links.

American Bitcoin and Gryphon Merge Toward Nasdaq Listing

American Bitcoin Corp., backed by Eric Trump and a subsidiary of Hut 8, has submitted a revised S-4 filing with the SEC alongside Gryphon Digital Mining to advance their merger plans. The combined entity will operate under the "American Bitcoin" brand and aims to list on Nasdaq under the ticker ABTC, targeting completion by Q3 2025.

This strategic consolidation reflects a maturing Bitcoin mining sector focused on scale, efficiency, and regulatory compliance.

Whale Moves 1,595 BTC to Binance

On-chain monitoring firm Onchain Lens detected a large transfer of 1,595 BTC (worth approximately $168.55 million) sent to Binance by an unidentified whale. While such deposits can signal potential selling pressure, they may also precede arbitrage opportunities or portfolio rebalancing.

Historically, large inflows to exchanges don’t always result in immediate sell-offs; context such as market timing and wallet history plays a crucial role in interpretation.

Kalshi and Polymarket Gauge Musk Political Odds

Prediction markets are buzzing over Elon Musk’s political ambitions. On Kalshi, the probability of Musk launching a new political party before year-end stands at 40%, while Polymarket puts it slightly higher at 43%.

These figures spiked after Musk stated he would form a new U.S. political party the day after the “Beautiful Big Bill” passes Congress — fueling speculation about tech leaders influencing policy and governance through alternative channels.


Frequently Asked Questions (FAQ)

Q: Why are Bitcoin ETF outflows happening despite long-term bullish sentiment?
A: Short-term outflows often reflect profit-taking or portfolio rebalancing by institutions. However, declining exchange reserves and strong on-chain accumulation suggest underlying strength in long-term holding behavior.

Q: What does low exchange supply mean for Bitcoin’s price?
A: Lower exchange balances reduce liquid supply, tightening market depth. Historically, this condition precedes upward price movements as fewer coins are available for sale during rallies.

Q: Are tokenized stocks like those on xStocks safe to trade?
A: Platforms like xStocks offer innovative access but come with regulatory and counterparty risks. Always research the underlying asset structure and ensure you're using trusted protocols with transparent backing.

Q: How serious is the Chrome V8 vulnerability for crypto users?
A: Extremely serious. Since many wallets rely on browser extensions, compromised browsers can lead to private key exposure. Always keep software updated and use hardware wallets when possible.

Q: What impact could Musk creating a political party have on crypto?
A: Musk has historically influenced crypto markets via social media. A formal political platform could amplify advocacy for pro-innovation policies, including blockchain regulation and digital asset adoption.

Q: Is DEX growth sustainable amid falling CEX volumes?
A: Yes — DEX growth is driven by structural advantages like non-custodianship, global access, and composability. As UX improves and liquidity deepens, this trend is likely to continue.
