As of July 2025, a striking revelation has emerged in the cryptocurrency landscape: out of the 2.4 million Bitcoin (BTC) held across major exchanges, only 47.3% are backed by verifiable proof of reserves. This means that approximately 1.25 million BTC—valued at tens of billions of dollars—remain unverified, raising concerns about transparency, solvency, and trust within the digital asset ecosystem.
This data underscores a growing need for accountability in centralized exchange operations, especially following past collapses linked to reserve mismanagement. While the adoption of proof-of-reserves practices has increased since the 2022 crypto downturn, the numbers show there's still a long way to go toward full financial transparency.
Understanding Proof of Reserves
Proof of reserves is a cryptographic audit mechanism that allows cryptocurrency exchanges to demonstrate they hold sufficient assets to cover user balances. It typically involves:
- Publicly verifiable wallet addresses
- Real-time blockchain snapshots
- Third-party auditing tools
These measures help confirm that exchanges aren’t engaging in fractional reserve practices—where only a portion of deposits are actually backed—similar to traditional banking systems but far riskier in the decentralized world.
Despite its importance, adoption remains inconsistent. Only a little over half of all exchange-held Bitcoin currently meet this standard, leaving millions of users exposed to potential insolvency risks.
Why the Gap Still Exists
Several factors contribute to the lack of full proof-of-reserves coverage:
1. Operational Complexity
Many exchanges operate across multiple custodial wallets, cold storage solutions, and third-party lending platforms. Aggregating and verifying these holdings in real time requires robust technical infrastructure.
2. Competitive Secrecy
Some platforms resist full disclosure due to competitive concerns. Revealing exact reserve levels could expose strategic positions or liquidity strengths to rivals.
3. Regulatory Ambiguity
While regulators like the U.S. SEC and EU’s MiCA framework are pushing for greater transparency, global standards for proof of reserves are still evolving. Without mandatory compliance, many exchanges opt for partial or infrequent audits.
4. Cost and Resource Constraints
Regular audits, especially those involving independent firms and on-chain verification, can be expensive and resource-intensive—particularly for smaller exchanges.
Institutional Moves Toward Transparency
Amid growing scrutiny, several companies and institutions are taking proactive steps to improve trust through blockchain-based verification and responsible asset management.
Hilbert Group Launches Bitcoin-First Treasury Strategy
Swedish digital asset investment firm Hilbert Group AB (Nasdaq: HILB B) recently announced a comprehensive cryptocurrency treasury strategy centered on Bitcoin. The plan, unanimously approved by its board, aims to position BTC as a core reserve asset.
A dedicated treasury committee will oversee the initiative, chaired by Chief Investment Officer Russell Thompson. The company is currently evaluating financing proposals from institutional partners to enable large-scale capital deployment across multiple tranches.
This move reflects a broader trend among public and private firms treating Bitcoin as a legitimate treasury reserve—similar to gold or cash equivalents—provided it comes with transparent backing.
Cel AI Expands Bitcoin Holdings
UK-listed company Cel AI has further diversified its balance sheet by purchasing 6.1794767 BTC at an average price of $109,791 per coin, investing a total of **$678,450.93**. This acquisition aligns with its ongoing strategy to strengthen digital asset reserves.
Earlier in June 2025, Cel AI raised £10 million ($12.7 million) specifically for Bitcoin investments, signaling strong institutional confidence in BTC as a long-term store of value—especially when holdings are transparently reported.
RWA Innovation: Bridging Physical Assets and Blockchain Trust
Beyond pure cryptocurrency holdings, the integration of real-world assets (RWA) onto blockchains is gaining momentum as a way to enhance transparency and unlock new financial models.
海南华铁 Digitizes $260 Billion in Equipment Assets
China-based infrastructure company 海南华铁 (603300.SH) has successfully digitized nearly 260 billion yuan (~$36 billion) worth of high-altitude work platform assets using Ant Chain’s MaaS (Module as a Service) trusted modules embedded in device T-boxes.
By recording operational data directly onto the blockchain, the company ensures “source-level trustworthiness,” meeting prerequisites for RWA financing. In addition, 海南华铁 signed a strategic partnership with the RWA Research Institute during the RWA Industry Conference to collaborate on:
- Revaluation of tokenized assets
- Development of industry-wide standards
- Global circulation frameworks for RWAs
This case illustrates how blockchain verification isn’t limited to crypto exchanges—it’s becoming essential across industries where asset provenance and financial integrity matter.

Frequently Asked Questions (FAQ)
Q: What does "proof of reserves" mean for cryptocurrency exchanges?
A: Proof of reserves is a verification process where an exchange proves it holds enough cryptocurrency to cover all user balances. It typically uses public wallet addresses and blockchain audits to provide transparency and prevent fractional reserve risks.
Q: Why is only 47.3% of exchange-held Bitcoin verified?
A: Many exchanges face technical, regulatory, or competitive challenges in implementing full proof-of-reserves systems. Some avoid disclosure due to operational complexity or fear of revealing strategic positions.
Q: How can investors protect themselves from exchange insolvency?
A: Users should prioritize exchanges that publish regular, third-party-audited proof-of-reserves reports. Additionally, storing large amounts in self-custody wallets significantly reduces counterparty risk.
Q: Is Bitcoin safe as a corporate treasury asset?
A: When properly managed—with secure custody and transparent reporting—Bitcoin can be a viable treasury asset. Companies like MicroStrategy and Cel AI demonstrate growing institutional confidence in BTC’s long-term value.
Q: What role does blockchain play in real-world asset (RWA) tokenization?
A: Blockchain provides immutable records of ownership, usage, and value history for physical assets like equipment or real estate. This enhances trust, enables fractional ownership, and opens access to global capital markets.
Q: Can proof of reserves prevent another FTX-style collapse?
A: While not foolproof, regular and independently verified proof-of-reserves audits make it significantly harder for exchanges to hide insolvency or misuse customer funds, thereby reducing systemic risk.
Final Thoughts
The fact that less than half of exchange-held Bitcoin have verifiable reserves in July 2025 is both alarming and instructive. It highlights persistent vulnerabilities in the centralized crypto ecosystem while also spotlighting positive developments—from institutional treasury strategies to blockchain-backed RWA projects—that are setting new standards for accountability.
As investor expectations rise and regulations tighten, exchanges and institutions alike must embrace transparency not just as a best practice—but as a foundational requirement for long-term credibility.
The future of digital finance depends not only on innovation but on trust built through verifiable truth. And in a world where code is law, proof should never be optional.
