Bitcoin's Realized Cap Declines Amid Weak Demand Indicators

Bitcoin's market dynamics have shifted as its Realized Cap experienced its first contraction in 28 days, indicating a potential downturn in demand. As of September 17, Bitcoin was priced around $76,458, just below the $76,700 True Market Mean identified by Glassnode. This level serves as an important on-chain cost-basis reference.

On September 15, Glassnode reported a decline in Realized Cap, which estimates Bitcoin's aggregate on-chain cost basis by valuing coins at their last movement price. This contraction suggests that coins are being repriced lower, rather than a significant outflow of cash from the blockchain.

Additionally, the ETF market has shown concerning trends, with Farside Investors reporting net outflows of $450.4 million and $295.9 million on consecutive days. While these figures do not directly correlate with Bitcoin's price movements, they reflect a broader trend of diminishing demand.

Glassnode has identified critical support levels for Bitcoin, with the next significant cost basis around $71,300, which represents the average acquisition price for short-term holders. A break below this level could signal further weakness, while reclaiming the $76,700 mark with improved Realized Cap growth would suggest a recovery.

New Insights on Bitcoin ETFs

• Cumulative net inflows across all Bitcoin ETF products have settled around $55B, down from a peak of $63B in October 2025.
• Recent inflows saw approximately $3.8B invested in spot Bitcoin ETFs over a three-week period in late August and early September 2026.
• Mid-September 2026 experienced significant outflows, including single-day reductions of $296M and $450M on September 15 and 16 respectively.
• Total Bitcoin held across all ETF products is currently around 649K BTC.
• BlackRock’s iShares Bitcoin Trust (IBIT) has cumulative inflows exceeding $63B, while Grayscale’s GBTC has seen cumulative net outflows surpassing $27B.
• The recent recovery in net inflows to $55B suggests a potential return of buyers to the market.

New Insights on Bitcoin Futures Markets

Recent analysis reveals a significant shift in Bitcoin futures markets, with the percentage of coin-margined contracts dropping from approximately 70% in early 2021 to around 12% by mid-2026. This change indicates a major transition towards stablecoin and USD-backed alternatives.

This structural change enhances market stability by reducing the risk associated with collateral that fluctuates in value alongside the asset being traded. With stablecoin or USD margins, the collateral value remains consistent, preventing the accelerated losses that can occur with Bitcoin-margined contracts.

The trend has persisted through various market phases, suggesting it is not merely a temporary adjustment. Major exchanges like Binance, Bybit, and OKX have all played a role in this transition, leading to a more predictable and manageable trading environment for leveraged positions.

As a result, the derivatives market has effectively mitigated one of its most significant risk factors, making it more appealing to institutional investors and simplifying portfolio management for traders.

New Insights on Bitcoin Transfer Figures

A recent working paper from the Bank for International Settlements (BIS), published on September 15, reveals significant discrepancies in Bitcoin transfer-value estimates, with variations of up to six times depending on the measurement approach used. This finding highlights the complexity of interpreting blockchain data and emphasizes that different aggregation methods can lead to vastly different economic interpretations of the same transactions.

The paper identifies three structural sources of measurement divergence: transaction aggregation, smart-contract programmability, and cross-chain activity comparisons. It notes that while public blockchains provide transparent records, the interpretation of these records is crucial in determining their economic significance.

Additionally, the study found that trading activity is heavily concentrated around stablecoins, with the economic meaning of stablecoin transactions varying across different blockchains. For instance, on Ethereum, stablecoin activity is often linked to smart-contract interactions, while on Tron, it tends to be associated with transactional and store-of-value purposes.

The authors advocate for a more nuanced approach to on-chain indicators, suggesting that they should be viewed as approximations rather than precise measures of economic activity. They recommend that methodologies behind these figures be made explicit to enhance their usefulness in understanding network behavior.

New Developments in Ethena Labs

• Ethena Labs, founded by Guy Young in March 2023, aims to reduce dependency on Bitcoin price fluctuations by focusing on tokenized real-world assets.
• The synthetic dollar USDe launched publicly in February 2024, initially relying on a delta-neutral mechanism involving crypto collateral and perpetual futures contracts.
• USDe's supply peaked at over $14 billion in October 2025 but fell to approximately $4 billion by late August 2026, indicating a 70% contraction.
• Ethena has reallocated $200 million into tokenized AAA-rated collateralized loan obligations to generate revenue independent of crypto market conditions.
• On September 1, 2026, Ethena launched Ethena Pay on the Avalanche network, allowing USDe holders to spend their synthetic dollars via Visa cards with yields up to 6%.
• Ethena completed a SOC 2 Type II audit without exceptions, enhancing its credibility for institutional investments.
• A proposed fee-switch mechanism aims to direct 95% of net revenue toward ENA token buybacks, contingent on USDe supply reaching $7.5 billion.
• Ethena's strategic direction mirrors broader trends in crypto, with other protocols also diversifying revenue sources to mitigate cyclical risks.
