This monetary easing signaled increased liquidity ahead, benefiting risk assets like cryptocurrencies. As a result, prices rebounded in late September. The total crypto market cap fluctuated between $2 trillion and $2.5 trillion during the quarter. Notably, Bitcoin (BTC) strengthened its dominance, with its market cap share reaching 53% on September 30, the highest level this year.
Meanwhile, the ETH/BTC exchange rate dropped to 0.038, a three-year low, indicating underperformance of Ethereum relative to Bitcoin. Stablecoin supply also grew, reaching $172 billion by quarter-end—an increase of 7.16% from Q2—reflecting growing on-chain activity and investor readiness to re-enter markets.
Key Cryptocurrency Performance
- BTC: Strong dominance resurgence
- ETH: Weaker price momentum despite lower fees
- TRX & XRP: Outperformed peers with solid returns
Bitcoin (BTC) Analysis: Strength in Fundamentals
Despite a slight dip in derivatives activity, Bitcoin’s underlying fundamentals remained robust throughout Q3.
The average daily open interest in BTC options stood at $20.2 billion, down 1.53% from the previous quarter. However, trading volumes surged, especially around the September expiry date, which recorded the highest unwinding since April—indicating strong institutional participation.
ETF and Investment Trends
BTC ETFs saw net inflows of $4.34 billion in Q3, reinforcing institutional confidence. This sustained demand helped support price levels even during broader market corrections.
Network Health & Mining Activity
Bitcoin’s network security continued to strengthen:
- Mining difficulty rose to 88.40 T
- Hashrate reached 659.19 EH/s
These metrics reflect increasing competition among miners and long-term bullish sentiment within the mining community.
Additionally, the number of unique BTC holder addresses hit 19.76 million, up 0.21% from Q2—suggesting steady accumulation despite price swings.
Layer 2 Growth
One of the most promising developments was the 20.47% quarterly increase in BTC Layer 2 Total Value Locked (TVL). Innovations like Stacks, Lightning Network integrations, and emerging ordinal-based protocols are expanding Bitcoin’s utility beyond store-of-value use cases.

Ethereum (ETH) Analysis: Lower Fees, Slower Activity
Ethereum experienced mixed signals in Q3. While network efficiency improved, overall market engagement weakened.
Derivatives and ETF Flows
ETH options average open interest declined sharply by 37.15% to $6.1 billion**, signaling reduced speculative interest. The launch of ETH ETFs in Q3 failed to generate sustained inflows; instead, the sector recorded net outflows of **$523 million. Although outflows slowed over time, investor caution remained evident.
Network Efficiency Improvements
Gas prices dropped significantly—averaging 8.88 Gwei, down 38.01% from Q2’s 14.33 Gwei—making transactions more affordable and improving user experience across DeFi and NFT platforms.
Staking and Supply Dynamics
Ethereum’s staked supply grew to 34.79 million ETH, a 4.5% increase from last quarter. However, Q3 marked a shift from deflationary to mildly inflationary issuance, with an annualized inflation rate hovering around 0.6% due to reduced burn rates.
Layer 2 Ecosystem Contraction
Despite cheaper gas, Ethereum Layer 2 TVL fell by 10.13% to $38.9 billion. This decline suggests users may have rotated capital toward alternative ecosystems or withdrew amid lower yield opportunities.
Top-performing sectors on Ethereum remained concentrated in DeFi, MEV bots, and automated trading tools, showing continued demand for advanced financial infrastructure.
Other Major Blockchains: Solana Shines, TON and Sui Gain Traction
While BTC and ETH dominated headlines, several alternative blockchains delivered strong performance metrics.
Solana: DeFi Momentum Continues
Solana’s DeFi TVL grew by 20.79%, led by Raydium, its leading decentralized exchange (DEX). The ecosystem’s liquid staking token JitoSOL captured the largest share of staked SOL, enhancing capital efficiency.
However, MEME coin speculation fueled rapid token launches across multiple chains, contributing to short-term volatility rather than sustainable growth.
TON and Sui: Rising Engagement
- TON Network: Averaged 605,500 daily active addresses and 1.9 million transactions per day
- Sui Network: Saw higher engagement with 699,700 daily active addresses and 3.38 million transactions daily
Although TON’s DeFi TVL dropped by 26.25%, its user base remained strong—driven initially by games like Catizen. Post-airdrop, however, activity declined rapidly, highlighting challenges in retaining users without ongoing incentives.
DeFi Landscape: Consolidation and Revenue Leaders
Decentralized Finance (DeFi) remained a core driver of on-chain value creation.
Q3 DEX trading volume totaled $395 billion, with the top five platforms accounting for nearly 80% of activity:
- Uniswap: 33.8%
- Others: PancakeSwap, Curve, SushiSwap, Raydium
Total protocol revenue reached $191 million, led by:
- Pump.fun: $63 million (primarily from meme coin launches)
- MakerDAO, Uniswap, PancakeSwap, Aave
This concentration highlights both innovation and centralization risks within the DeFi space.
NFTs & GameFi: Ethereum and Polygon Lead Trading
NFT markets remained concentrated on two chains:
- Ethereum: $5.4 million average daily trading volume
- Polygon: $4.3 million
GameFi sector valuation hit $21.42 billion, up 6.25% quarter-over-quarter. Notably, Pixels, a cross-chain Web3 farming game, led in daily active wallet counts—demonstrating growing appeal of gamified token economies.
Security Incidents: A Wake-Up Call
Q3 recorded 93 hacking incidents, resulting in approximately $784 million** in losses—though about **$27.54 million was recovered.
Attack vectors included:
- Smart contract vulnerabilities: 21 incidents
- Private key compromises / account takeovers: 36 incidents
These numbers underscore the urgent need for comprehensive security audits, multi-sig governance, and proactive monitoring systems across Web3 projects.
Industry Funding Trends: Downward Pressure with Exceptions
A total of 324 projects raised funds in Q3—a decline of 25.78% from Q2—with total capital raised amounting to $2.4 billion (15.21% drop).
However, one bright spot emerged: tools and information services saw a remarkable 69.71% growth, becoming the only sector with positive momentum—reflecting rising demand for analytics, developer tooling, and compliance infrastructure.
Outlook: Macro Tailwinds Meet On-Chain Evolution
The Federal Reserve’s decision to cut interest rates by 50 basis points in early September marked the start of a new monetary easing cycle. While short-term uncertainty persists, lower borrowing costs and rising liquidity typically benefit high-growth assets like cryptocurrencies.
Historically, such environments have preceded bull runs in digital assets—driven by increased risk appetite and capital rotation into innovative sectors.
As Layer 2 scaling matures and institutional adoption deepens through ETFs and regulated products, the foundation for sustainable growth appears stronger than ever.
