BlackRock published a "Quantum Computer" warning about Bitcoin (BTC)! Here is the meaning.

Although the encryption systems seen as the crypto assets firewall have maintained their durability for many years, recent warnings from the world's largest asset manager, BlackRock, show that this security may not last forever.

In its updated application regarding the (ETF) for the iShares Bitcoin Trust, BlackRock significantly expanded its risk disclosures concerning threats posed by quantum computers. The new filing included more comprehensive statements about how technological advancements could undermine the fundamental security framework of Bitcoin.

In a document that previously only mentioned the potential risks posed by "breakthroughs in mathematics, algebraic geometry, and quantum computing," these sections have now been enriched with more detailed scenarios on how Bitcoin's cryptographic algorithms could be broken.

Bloomberg ETF analysts James Seyffart and Eric Balchunas interpreted BlackRock's new language as part of a broader risk disclosure update. Seyffart stated in a post on X (, formerly known as Twitter), "To be clear, these are just basic risk disclosures. It is completely standard procedure for them to note potential issues related to each product or asset being invested in."

The risk section spanning from page 16 to page 65 of the document addresses a wide range of topics, from quantum threats and regulatory pressures to potential hard fork scenarios, price volatility, and the concentration of mining hardware in China. Additionally, factors such as the possible market impacts of Donald Trump’s Bitcoin reserves and the high energy consumption of mining activities are also included on the list.

On the other hand, the year 2025 is witnessing a global momentum in quantum science. The United Nations aims to accelerate quantum research by declaring this year as the "International Year of Quantum Science and Technology."

However, academics like quantum expert Pierre-Luc Dallaire-Demers from the University of Calgary indicate that a quantum computer capable of threatening the cryptographic security of Bitcoin is at least five to seven years away.
