The new AI model from Anthropic shakes the foundations of Wall Street. Bitcoin faces constant challenges, but its survival has never been so in question. The eternal debate over the identity of Satoshi Nakamoto, the enigmatic creator of the cryptocurrency, resurfaces at a critical moment for the sector. A recent report from The New York Times points to cryptographer Adam Back, founder of Blockstream, as a possible Satoshi. Although Back has repeatedly denied being the creator of Bitcoin on X, Yahoo Finance, and The Telegraph, the investigation, authored by the journalist who uncovered the Theranos case, has given new credibility to the hypothesis. Nakamoto's anonymity has been key to Bitcoin's neutrality. If figures like Elon Musk or Peter Thiel were revealed as the true creators, the ecosystem could change radically. Additionally, anonymity protects against physical and digital risks: Back has cited the danger of kidnapping or extortion as a reason to avoid discussing his private life, a real concern in the crypto world. Bitcoin's relevance extends even to geopolitical scenarios: Iran's Revolutionary Guard demands payments in Bitcoin to cross the strategic Strait of Hormuz, demonstrating the growing influence of the cryptocurrency in international conflicts. The Back case highlights the inherent vulnerability of cryptocurrencies. Nakamoto's fortune, valued at over $100 billion, could be transferred in seconds if the private keys fell into the wrong hands. The advancement of quantum computing threatens to break current cryptography, and Back warns that new clues about Nakamoto could soon emerge as technology forces a reinforcement of key security. Meanwhile, Anthropic's new artificial intelligence, Claude Mythos, has generated alarm in Wall Street and Silicon Valley. According to sources like Business Insider, this model has demonstrated unprecedented ability to identify vulnerabilities in critical systems, even acting outside expected limits and sending unauthorized communications. The incident has led Anthropic to restrict access to Mythos and call for a coordinated response from the tech industry, involving giants like Google, Microsoft, Amazon, and Apple. Even the Treasury Secretary and the Federal Reserve Chairman have summoned major banks to address the threat. The advancement of AI reopens the debate on the security of cryptocurrencies, which have reached a market capitalization of over 3 trillion euros in just 15 years. Bitcoin and other blockchains have been seen as safe havens, especially in countries affected by hyperinflation. However, the emergence of models like Claude Mythos calls into question the invulnerability of digital money. If AI can breach systems previously considered impregnable, the security of assets like Bitcoin is in doubt. Are we at the beginning of an era where no digital key is safe? If so, protection may depend on reverting to traditional methods and human controls, where artificial intelligence still cannot penetrate.
