Long-standing relationships between central banks and Bitcoin have been filled with skepticism and hesitation. Although many monetary authorities have considered issuing central bank digital currencies, few have seriously contemplated holding Bitcoin as a reserve asset. However, the Czech National Bank has launched a pilot project to test the direct custody of Bitcoin, a move that could fundamentally change this situation—potentially reshaping our understanding of sovereign wealth management in the digital age.

To understand the significance of this development, CoinRank interviewed Trezor analyst Lucien, who has been tracking the Bitcoin market and the evolution of self-custody for a long time. Based in Prague, Lucien has an in-depth understanding of the Czech Bitcoin ecosystem, and he offers unique insights into why the Czech National Bank's (CNB) initiative is important and its implications for future monetary policy and financial sovereignty.

Operational Sandbox Approach

"This is not what many headlines suggest," Lucien clarified at the beginning of the conversation. "The Czech National Bank has not immediately included Bitcoin in its official reserves. They have created a so-called operational sandbox—a test portfolio worth $1 million that includes Bitcoin, a dollar stablecoin, and a tokenized bank deposit."

He explained that this controlled environment has specific purposes: to build internal capabilities before making a larger commitment. "The sandbox environment allows the central bank to gain practical experience in various aspects, from custody and key management to anti-money laundering compliance, accounting, as well as on-chain settlement and auditing," Lucien elaborated. "This is a learn-by-doing approach, which is in stark contrast to the theoretical discussions that have dominated the central banking community for years."

When asked about the timing of this initiative, Lucien pointed out an interesting contradiction. "Just ten months before the Italian National Bank launched this pilot program, ECB President Christine Lagarde had emphatically stated that no central bank in the ECB Governing Council would engage with Bitcoin. Yet now, we see a member state doing just that." He paused and added, "This disconnect reveals significant differences in innovation and risk management among different monetary authorities—some ideologically oppose it, while others are willing to experiment."

Lucien noted that this initiative aligns closely with the overall strategy of Brazilian Central Bank President Roberto Campos Neto. "Neto has openly discussed the potential of Bitcoin as a long-term investment and has guided the bank towards reserve diversification, including significant purchases of gold. This test portfolio is essentially a thoughtful concept he proposed back in January 2025, rather than a passive reaction to market pressure or public sentiment."

Bitcoin as an Anonymous Asset

In our discussion, Bitcoin was frequently referred to as "digital gold." When asked about this comparison, Lucien responded, "I think this characterization is fundamentally accurate, but there are some important nuances. The key is to understand Bitcoin as an anonymous asset, similar to gold, whose sovereign value derives from direct ownership rather than claims against other institutions."

He contrasted this with traditional foreign exchange reserves: "The operational principle of foreign exchange reserves is entirely different. They are ultimately claims against another government system, which inevitably introduces political risk. Bitcoin and gold do not carry this risk because institutions can hold them directly."

When asked whether Bitcoin is truly superior to gold, Lucien became more animated. "Bitcoin may outperform gold in practical terms. Gold requires vaults, insurance, armed transport, and assay verification—all of which incur significant costs and complex logistics. Bitcoin requires proper key management, but once institutions master this capability, the security and transfer efficiency of the asset improve dramatically. Settlements take hours instead of weeks, and the cost structure is entirely different."

He also emphasized another key advantage: "The inherent transparency that Bitcoin offers is something gold cannot match. For example, El Salvador shares its Bitcoin holdings on-chain in real-time, allowing anyone to independently verify. But for gold reserves, the public can only trust the data published by central banks. With Bitcoin, this transparency is built into the protocol itself."

Key Management Challenges

When discussing the operational challenges faced by central banks, Lucien did not hesitate to say, "If there is one obstacle that stands out in operations, it is key management. This is the biggest challenge because it is extremely complex and lacks any safety net—Bitcoin transactions do not have a 'cancel' button. Any mistake in key management could mean permanent, irreversible loss."

He continued, "The good news is that financial institutions have, in principle, understood multi-signature authorization. For decades, banks have used dual approval systems, requiring multiple signatures for larger transactions. Bitcoin multi-signature is essentially an encrypted version of this concept."

But Lucien emphasized that the key difference lies in, "The challenge is in the execution mechanism: it is a mathematical principle, not an internal policy. You cannot override the rules or make exceptions, which means that governance and signing procedures must be flawless from the start."

He analyzed the specific issues that keep central bank officials awake at night: "Who holds which keys? What is the signing threshold? What happens if someone leaves the institution or an emergency occurs? How do you securely rotate keys? How do you implement a backup system without introducing new vulnerabilities? Each question involves trade-offs that must be carefully weighed."

"These issues are solvable," Lucien assured, "but they require building entirely new operational capabilities. This is precisely why the CNB is adopting a sandbox approach—it allows them to address these challenges under limited risk before scaling up."

The Unique Position of the Czech Republic

As the conversation shifted to the Czech Republic, Lucien's enthusiasm for his homeland's Bitcoin ecosystem was evident. "The existing Bitcoin infrastructure in the Czech Republic is often overlooked," he said. "Unlike many countries that need central banks to guide public acceptance of Bitcoin, the Czech public does not require encouragement. They have been enthusiastically using Bitcoin for over a decade."

He listed a series of impressive contributions: "The Czech Republic has the world's first mining pool. The first hardware wallet, Trezor, was also born here, and we have contributed to many Bitcoin standards that are still in use today. Prague is often referred to as the Bitcoin capital of the world, with over 1,000 places nationwide where Bitcoin transactions can be made—making it one of the most concentrated areas for Bitcoin trading in Europe."

"This is not just a theoretical application," Lucien emphasized, "it has been integrated into everyday business activities. The world's first Bitcoin conference was held in Prague in 2011, and today, the city hosts BTC Prague, the largest pure Bitcoin conference in Europe."

When asked about the regulatory environment, he highlighted a key advantage: "Czech law has supported the adoption of Bitcoin in a practical way. Holding Bitcoin for three years or more is tax-free. Daily Bitcoin payments are also tax-exempt. These policies indicate that the government understands the potential of Bitcoin and has created an environment that encourages both long-term holding and convenient daily use—this is rare within the European regulatory framework."

Lucien offered an interesting perspective on the relationship between public and institutional adoption: "The public's level of understanding is far ahead of many EU countries. The pilot project by the Italian National Bank is not aimed at encouraging public adoption, but rather to allow the central bank to catch up and enhance its capabilities in potential reserve management. This subverts the usual narrative that monetary authorities lead while the public follows."

Comparing Regulatory Approaches

In discussing how other jurisdictions might emulate the Czech model, Lucien made an important distinction. "It is crucial to understand that there are two different types of initiatives that are often conflated," he explained. "Singapore, Switzerland, the UAE, and an increasing number of U.S. states have been building comprehensive regulatory frameworks for the retail cryptocurrency market—including licensing for exchanges, custodial service providers, and stablecoin issuers, as well as tokenization of traditional securities."

He continued, "The CNB's pilot project represents a fundamentally different situation. It is an internal operational experiment by the central bank itself. It is not a public-facing regulatory framework, but rather a question of holding assets on the monetary authority's own balance sheet. These are independent institutional decisions that are not necessarily related to one another."

He emphasized the uniqueness of the Czech approach: "The Czech Republic is simultaneously pursuing both methods. They have established reasonable retail rules—daily Bitcoin payments are tax-exempt, and there is a three-year capital gains tax exemption—while now the central bank is actively testing the feasibility of holding Bitcoin as reserves. Most jurisdictions only adopt one of these approaches, rather than balancing both."

When asked about the Czech regulatory philosophy, Lucien candidly stated, "It emphasizes learning in practice rather than endless theoretical debates. While other regions are still drafting discussion papers and policy proposals, the Czech National Bank has already taken direct steps to enhance operational capabilities. This is a pragmatic approach that prioritizes practical experience over bureaucratic discussions."

Implications for the Future of Currency

As the conversation drew to a close, I asked Lucien for his outlook on the future. "Predicting the exact trajectory of the global monetary landscape over the next ten to fifteen years is speculative," he admitted, "but certain fundamentals remain clear. The supply schedule and monetary policy of Bitcoin are fixed and transparent—you know exactly what you will get. The certainty of fiat currencies is much lower because their supply can change based on political decisions."

He believes early adopters hold a significant advantage: "Central banks that understand Bitcoin as a neutral sovereign asset—especially smaller, more agile central banks—may gain considerable advantages. They can act more quickly than large institutions constrained by political consensus and bureaucratic inertia, which could position them favorably in the next monetary crisis."

Lucien emphasized, "What Bitcoin fundamentally offers is choice. Regardless of jurisdiction or institutional size, it applies equally to everyone and provides the same safeguards. Whether central banks choose to use this tool in the coming years, and how effectively they implement it, will likely determine which monetary authorities can operate successfully and which will struggle."

He cautiously clarified, "This is not about replacing fiat currency with Bitcoin; rather, it is about providing an additional option for reserve diversification."

In his concluding remarks, Lucien once again referenced the Swiss National Bank's pilot project: "Institutions that are now building Bitcoin custody capabilities will have an advantage over those that ignore this area. Although the Swiss National Bank's pilot project is small, at only $1 million, the operational experience they are accumulating may become invaluable as the monetary landscape continues to evolve. In a world where sovereign financial instruments are becoming increasingly scarce, understanding how to custody anonymous assets without counterparty risk represents a significant strategic advantage—and this advantage will accumulate over time."

"Currently, the Czech National Bank's experiment is still just that—an experiment," he concluded. "However, its very existence challenges long-held perceptions of what central banks can and should do. Whether other monetary authorities will follow suit remains to be seen, but the door has been opened. In the realm of monetary policy, as in many other areas, the gap between theory and practice often matters more than the theory itself. The Czech National Bank has chosen practice, thereby providing a roadmap for other central banks exploring this path."
