Citi: Quantum computing breakthroughs are accelerating, Bitcoin faces significant quantum risks

ChainCatcher news, Citibank stated in its latest report that quantum computing technology is advancing faster than the market expects, rapidly accelerating the potential security risks faced by cryptocurrencies and internet infrastructure, with Bitcoin considered one of the assets with the greatest risk exposure. The report notes that the ECDSA elliptic curve encryption system currently used by Bitcoin could, in theory, be broken by a sufficiently powerful quantum computer. In the future, attackers may be able to derive private keys from publicly available public keys, enabling them to forge transactions and steal assets.

Citi analyst Alex Saunders explained that, due to Bitcoin’s relatively conservative governance mechanism and slow protocol upgrade speed, it is more difficult for Bitcoin to quickly complete a quantum-resistant upgrade compared to PoS networks like Ethereum. The report estimates that around 6.5 million to 6.9 million BTC face potential quantum risks because their public keys have been exposed, accounting for about one-third of the current circulating supply and valued at roughly $450 billion at present prices. This includes some early P2PK addresses and wallets believed to belong to Satoshi Nakamoto.

Citi also warns of the “Harvest Now, Decrypt Later” risk, meaning attackers may collect encrypted data now and decrypt it once quantum computing power matures in the future. However, Citi remains optimistic about the long-term adaptability of the crypto industry, believing that blockchains can still migrate through post-quantum cryptography and protocol restructuring. The report mentions that upgrade proposals BIP-360 and BIP-361, currently being discussed by the Bitcoin community, warrant attention.

Retail investors are bottom-fishing AI stocks, with a net purchase of $9.1 billion in one week, marking a 15-year record! According to Citadel Securities data, funds are highly concentrated in semiconductors and AI infrastructure. However, this is not a broad-based buying frenzy, but rather a directional overweight, with buying skewed to the 90th percentile of the past year.

Microsoft adds over $130 billions in new data center leases, plans to more than double computing power

Microsoft plans to increase its global data center capacity from approximately 12 GW to over 38 GW. In a single quarter, it added over $130 billions in new lease agreements, bringing its total uncommitted lease commitments to $329.1 billions—a more than 67% increase over the previous quarter and the largest quarterly jump in leasing on record. This move is aimed at alleviating the long-term computing power bottleneck, as capacity shortages have already caused some customers to turn to competitors.
