For a long time, the relationship between central banks and Bitcoin has 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 testing the direct custody of Bitcoin, a move that completely changes this situation—it may reshape our understanding of sovereign wealth management in the digital age.
To understand the significance of this development, CoinRank interviewed Lucien, an analyst at Trezor, who has long tracked the dynamics of the Bitcoin market and self-custody. Based in Prague, Lucien has a deep understanding of the Czech Bitcoin ecosystem. He offered unique insights into why this initiative by the Czech National Bank (CNB) is important and its implications for future monetary policy and financial sovereignty.
Operational Sandbox Approach
"This is not what many news stories have suggested," Lucien clarified at the beginning of the conversation. "The Czech National Bank has not immediately incorporated Bitcoin into its official reserves. They created what is called an operational sandbox—a test portfolio worth $1 million containing Bitcoin, a dollar stablecoin, and a tokenized bank deposit."
He explained that this controlled environment has a specific purpose: to build internal capabilities before making a larger commitment. "The sandbox environment allows the central bank to gain practical experience in everything from custody and key management to anti-money laundering compliance, accounting, and on-chain settlement and auditing," Lucien elaborated. "It's a learn-by-doing approach, starkly different from the theoretical discussions that have dominated the central banking world for years."
When asked about the timing of this initiative, Lucien pointed to an interesting contradiction. "Just ten months before the Italian National Bank launched this pilot, ECB President Christine Lagarde stated categorically that no central bank on the ECB's General Council would venture into Bitcoin. Yet now, we see a member state doing exactly that." He paused, then added, "This disconnect reveals important differences in innovation and risk management among different monetary authorities—some remain ideologically opposed, while others are willing to experiment."
Lucien noted that this move aligns closely with the overall strategy of Brazilian National Bank President Ales Michl. "Michl has been openly discussing Bitcoin's potential for long-term investment and has guided the bank to diversify its reserves, including significant gold purchases. This test portfolio was essentially proposed by him in January 2025, reflecting a considered philosophy, not a reactive response to market pressures or public sentiment."
Bitcoin as a Bearer Asset
During our discussion, Bitcoin was frequently referred to as "digital gold." When asked about this comparison, Lucien responded: "I think the analogy is fundamentally accurate, but with some important nuances. The key is to understand Bitcoin as a bearer asset, similar to gold, whose sovereign value derives from direct ownership, not a claim on another institution."
He contrasted this with traditional foreign exchange reserves: "Foreign exchange reserves operate on a completely different principle. They are claims on another government system, which inevitably introduces political risk. Bitcoin and gold do not have this risk because institutions can custody them directly."
When asked if Bitcoin might actually be superior to gold, Lucien became more animated. "Bitcoin may be operationally superior to gold. 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 an institution masters this capability, the security and efficiency of asset transfer are greatly enhanced. Settlement takes hours instead of weeks, and the cost structure is completely different."
He also highlighted another key advantage: "The inherent transparency Bitcoin offers is something gold simply cannot match. For example, El Salvador shares its Bitcoin holdings on-chain in real-time, verifiable by anyone independently. For gold reserves, the public must trust the data published by the central bank. For Bitcoin, this transparency is built into the protocol itself."
Key Management Challenges
When discussing the operational challenges facing central banks, Lucien did not hesitate: "If there's one operational hurdle that stands out, it's key management. It's the biggest challenge because it's complex and offers no safety net—there's no undo button for Bitcoin transactions. Any mistake in key management could mean permanent, irreversible loss."
He continued: "The good news is that financial institutions already understand the principle of multi-level authorization in principle. Banks have used dual-approval systems for decades, where larger transactions require multiple signatories. Bitcoin multisig is essentially the cryptographic version of this concept."
But Lucien emphasized a key difference: "The challenge lies in the enforcement mechanism: it's mathematical, not based on internal policy. You can't override the rules or make exceptions, which means governance and signing procedures must be perfect from the start."
He broke down the specific questions that keep central bankers awake at night: "Who holds which keys? What is the signing threshold? What happens if someone leaves the institution or there's an emergency? How to securely rotate keys? How to implement backup systems without introducing new vulnerabilities? Each question involves trade-offs that must be carefully weighed."
"These problems are solvable," Lucien assured, "but it requires building entirely new operational capabilities. This is precisely why the CNB is using a sandbox approach—it allows them to address these challenges with limited risk before scaling up."
The Unique Position of the Czech Republic
As the conversation turned to the Czech Republic, Lucien's enthusiasm for his home country's Bitcoin ecosystem was evident. "The existing Bitcoin infrastructure in the Czech Republic is often overlooked," he said. "Unlike many countries where the central bank needs to guide public acceptance, the Czech public needs no encouragement. They have been using Bitcoin enthusiastically for over a decade."
He listed a series of impressive contributions in one breath: "The Czech Republic is home to the world's first mining pool. The first hardware wallet, Trezor, was born here, and we have contributed to many Bitcoin standards still in use today. Prague is often called the world's Bitcoin capital, with over 1,000 places in the country where you can transact in Bitcoin—one of the highest concentrations in Europe."
"This isn't just theoretical adoption," Lucien emphasized. "It's integrated into daily commerce. 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 already supports Bitcoin adoption in practical ways. Holding Bitcoin for three years or more is tax-free. Daily Bitcoin payments are also tax-free. These policies show that the government understands Bitcoin's potential and has created an environment that fosters both long-term holding and everyday use—a rarity in European regulatory frameworks."
Lucien offered an interesting perspective on the relationship between public and institutional adoption: "The public is far ahead of many EU countries. The CNB's pilot is not about encouraging public adoption but about allowing the central bank to catch up and build its capabilities for potential reserve management. This flips the usual narrative where monetary authorities lead and the public follows."
Comparative Regulatory Approaches
Discussing whether other jurisdictions might follow the Czech model, Lucien made an important distinction. "It's crucial to understand that there are two different types of initiatives that are often confused," he explained. "Singapore, Switzerland, the UAE, and increasingly the US, have been building comprehensive regulatory frameworks for the retail crypto market—including licensing for exchanges, custody providers, stablecoin issuers, and the tokenization of traditional securities."
He continued: "The CNB's pilot represents a fundamentally different situation. It's an internal operational experiment by the central bank itself. It's not a public-facing regulatory framework but a matter of the monetary authority holding assets on its own balance sheet. These are separate institutional decisions that are not necessarily related to each other."
He highlighted the uniqueness of the Czech approach: "The Czech Republic is pursuing both approaches simultaneously. They have sensible retail rules—tax-free daily Bitcoin payments, a three-year capital gains tax exemption—and now the central bank is actively testing Bitcoin for reserves. Most jurisdictions only take one approach, not both."
When asked about the Czech regulatory philosophy, Lucien was blunt: "It emphasizes learning by doing, not endless theoretical debate. While other regions are still writing discussion papers and policy suggestions, the Czech National Bank is directly building operational capability. It's a pragmatic approach that prioritizes practical experience over bureaucratic discussion."
Implications for the Future of Money
As the conversation neared its end, I asked Lucien about the future outlook. "Predicting the exact shape of the global monetary landscape ten to fifteen years from now is speculative," he admitted, "but certain fundamentals are clear. Bitcoin's supply schedule and monetary policy are fixed and transparent—you know exactly what you're getting. The certainty with fiat currency is much lower, as its supply changes based on political decisions."
He believes early adopters have a significant advantage: "Central banks that understand Bitcoin's role as a neutral sovereign asset—especially smaller, more agile ones—could gain considerable advantages. They can move faster than larger institutions constrained by political consensus and bureaucratic inertia, potentially giving them an edge in the next monetary crisis."
Lucien emphasized: "What Bitcoin fundamentally offers is choice. It is equally available to everyone, regardless of jurisdiction or institution size, and offers the same guarantees. Whether central banks choose to use this tool in the coming years, and how effectively they implement it, will likely determine which monetary authorities succeed and which struggle."
He cautiously clarified: "This is not about replacing fiat currency with Bitcoin; it's about providing an additional option for reserve diversification."
In his concluding remarks, Lucien returned to the CNB pilot: "Institutions building Bitcoin custody capabilities now have an advantage over those ignoring this space. The CNB pilot is small, at $1 million, but the operational experience they are accumulating could become invaluable as the monetary landscape continues to evolve. In a world where sovereign financial tools are increasingly scarce, knowing how to custody bearer assets without counterparty risk represents a significant strategic advantage—one that compounds over time."
"For now, the Czech National Bank's experiment remains just that—an experiment," he concluded. "Yet, its very existence challenges long-held assumptions about what central banks can and should do. Whether other monetary authorities will follow suit remains to be seen, but the door is now open. In monetary policy, as in many other fields, the gap between theory and practice often matters more than theory itself. The Czech National Bank has chosen practice, and in doing so has provided a reference roadmap for any other central bank that chooses to explore this path."
