Crypto Chaos: Hacks, Memes, and Market Meltdown | News
Let’s dive into the most important news in February
In this episode all four co-hosts, Alexander, Michael, Jonas and Manuel discuss the most relevant news of February: The negative crypto market sentiment, market cap and ETF AuM contractions and the reasons for that – among others the Bybit Hack Presidential Meme-Coins.
On Feb 21, one of the largest Crypto-Exchanges was hacked and a north-korean hacking group stole 1,4 bln USD worth of cryptocurrencies. The co-authors explain what happened and discuss how the attack and the biggest hack in history could have been prevented.
The Episode goes on to analyze and discuss the players and the mechanisms behind the issuance and price collapse of the Libra token that was supported by the Argentinian president Javier Milei and the interlinkage to the Melania Token.
After the bearish news, the record 2024 earnings of Tether and Coinbase are analyzed which reflect the positive crypto sentiment and market activity of last year – in particular in Q4.
The last section is devoted to European developments with an update on European MiCAR licenses for Stablecoins and crypto asset service providers as well as recent developments in the European projects on central bank digital currencies (CBDC). The ECB sees threats from USD denominated Stablecoins and wants to accelerate the digital Euro project as a respondes and on the other side wants to provide a solution in 2025 to connect Target services – existing settlement infrastructure – to newly emerging blockchain networks.

Bitcoin’s Quantum Vulnerability
Will Quantum Computers Break Bitcoin? A Deep Dive into Crypto’s Biggest Security Challenge
Quantum computing is no longer a distant prospect; it’s a reality. In this episode, co-host Michael Blaschke explores two significant developments that are impacting the relationship between quantum computing and blockchain: Google’s 105-qubit Willow chip and Ethereum’s proactive initiative for quantum resistance, known as "The Splurge."
Based on insights from his recent study at the FERI Cognitive Finance Institute, titled "Quantenzeitalter: Quantencomputing als Gamechanger für Finanz- und Realwirtschaft," Michael discusses the implications of quantum computing for both traditional finance and the cryptocurrency sector. The episode simplifies complex quantum concepts, highlighting how quantum computing poses both challenges and opportunities for traditional finance and crypto.
Key topics include:
Understanding Google’s Willow chip and its breakthrough capabilities
The fundamental differences between quantum and classical computing
How quantum computers could theoretically break current cryptographic systems
Bitcoin’s existing defense mechanisms against quantum threats
The crypto community’s response and preparation strategies
Vitalik Buterin’s vision for a quantum-resistant Ethereum
Practical implications for investors, institutions, and developers

Why the FDP demands a Bitcoin Reserve | German
We explore why the FDP has included the Bitcoin reserve initiative in their election program
The concept of a "strategic Bitcoin reserve" is gaining increasing international significance. What Donald Trump brought up in the US election campaign is now being seriously considered by a growing number of nations - including Brazil, Japan, Russia, and China alongside the US. The Czech Central Bank recently marked a milestone by becoming the first of its kind to officially announce plans to evaluate Bitcoin investments.
Against this backdrop, the new episode of Bitcoin, Fiat & Rock'n'Roll focuses on whether and how nations and central banks should use Bitcoin as a strategic reserve - a topic now also taken up by the FDP in the current German federal election campaign. Co-hosts Jonas Gross and Michael Blaschke discuss this with FDP member of parliament Frank Schäffler, who champions Bitcoin, crypto, and digital asset topics in the Bundestag like few others.
How does the FDP envision a Bitcoin reserve? The specific proposal suggests that the German Bundesbank and the European Central Bank (ECB) should diversify their currency reserves through Bitcoin. The Bundesbank's current gold reserves of 140 billion euros serve as a reference point. Schäffler emphasizes that this is a political appeal, as central banks remain independent in their investment decisions. Implementation would occur through active, systematic new acquisitions. Should the German state also buy Bitcoin according to the FDP's vision? You'll find out in the episode.
What are the challenges? Schäffler sees the biggest challenges in convincing the "establishment" and central banks. While ECB President Lagarde currently rejects Bitcoin investments, Schäffler considers it progress that the topic is being discussed at this level at all. He points to the positive developments of recent years: from the first tax recognition in 2013 to today's broad social acceptance of Bitcoin. What other challenges exist? You'll find out in the episode.
Enjoy the Episode!

Making Bitcoin accessible (with Relai CEO Julian Liniger)
Julian’s journey to becoming one of the most successful Bitcoin entrepreneurs in Europe
In this episode of Bitcoin, Fiat & Rock'n'Roll (BFRR), we speak with Julian Liniger, CEO and co-founder of Relai, about his mission to make Bitcoin accessible to everyone. Julian, a young Swiss entrepreneur, launched Relai in 2020 with the goal of simplifying Bitcoin investments.
By 2025, Relai has grown into one of Europe’s leading Bitcoin companies, serving approximately 140,000 clients who purchased nearly 13,000 BTC in 2024 alone. In December, the company successfully closed a $12 million funding round led by Ego Death Capital, a renowned Bitcoin-focused venture capital firm backed by prominent figures like Jeff Booth and Lyn Alden.
During the episode, Julian provides an in-depth and candid look at his journey, as well as the current state of Relai’s business. He discusses key topics such as valuation, revenues, and the company’s newly launched services: Relai Private, tailored for high-net-worth individuals, and Relai Business, designed to help small and medium enterprises acquire Bitcoin.
Currently operating across several European countries, Relai is poised for further growth. The company is planning a broader European expansion and has applied for a Crypto Asset Service Provider license under the Markets in Crypto Assets Regulation (MiCA). Expect to hear even more from them in the near future.

Zero-knowledge proofs: The future of privacy?
An Introduction to zero-knowledge proofs: their potential, applications, and challenges
In this episode of 'Bitcoin, Fiat & Rock'n'Roll' (BFRR), we explore zero-knowledge proofs (ZKPs), a technological innovation helping to protect privacy in our increasingly digital world. Co-host Jonas Gross discusses with Johannes Sedlmeir, postdoctoral researcher at the University of Luxembourg, how ZKPs work, their relevance, applications, and potential. They address key terminology and clarify common misconceptions.
Johannes illustrates ZKPs through a simple cave analogy: Imagine being trapped in a cave with two exits and a door in the middle. As the prover, you want to demonstrate to a verifier that you can open the door by exiting on either side - without revealing how. The verifier requests you exit on different sides repeatedly. After multiple successful attempts, the verifier becomes convinced you possess the secret without ever seeing it. Johannes extends this explanation with practical examples for different audiences – e.g., adults and engineers.
ZKPs have applications across numerous privacy-critical domains, including payments and identity, e.g., identification, authorization, and authentication. Recent technological advances have made many use cases practical today, while others face ongoing challenges. Which applications show the most promise and could reach billion-dollar market potential?
The episode concludes with Jonas and Johannes discussing when ZKPs might become mainstream technology, operating quietly behind most digital processes. Tune in to hear their insights.

Jahresrückblick 2024: Von Bitcoin-ETFs bis zur 100k-Marke
Das Host-Team blickt auf ein ereignisreiches Blockchain-Jahr zurück
In der letzten Episode des Jahres 2024 versammelt sich das komplette BFRR-Team zum traditionellen Jahresrückblick. Nach 321 Episoden und im sechsten Jahr des Podcasts blicken wir auf ein außergewöhnliches Kryptojahr zurück.
2024 war geprägt von wegweisenden Entwicklungen: Die Einführung der Bitcoin-ETFs im Januar markierte einen historischen Meilenstein mit über 110 Milliarden US-Dollar Assets under Management. Die Stablecoin-Marktkapitalisierung erreichte neue Höchststände, während die SEC ihre regulatorischen Aktivitäten im DeFi-Bereich intensivierte.
Wir evaluieren unsere Prognosen aus dem Vorjahr und diskutieren die wichtigsten Marktentwicklungen - von der Bitcoin-Preisentwicklung über institutionelle Adoption bis hin zu regulatorischen Veränderungen. Als besonderes Highlight kündigen wir zudem unsere Transformation zu einem englischsprachigen Format ab 2025 an.
Ein besonderer Dank gilt unseren treuen Hörern, Sponsoren und dem gesamten Team, die diesen Podcast über die Jahre zu dem gemacht haben, was er heute ist. Viel Spaß beim Hören!

Ganz im Gegenteil, des Öfteren stecken hinter den Affiliate-Links sogar Rabatt-Aktionen, sodass ihr auch noch Geld sparen könnt (z.B. beim Kauf von Bitcoin via Relai). Wir würden uns freuen, wenn ihr diese Links nutzt, um uns etwas zu unterstützen. Vielen Dank!
