Jim Cramer said he will liquidate his Bitcoin holdings, concerned about the threat of quantum computing to its security

Former hedge fund manager and CNBC host Jim Cramer stated that due to concerns about quantum computing threatening Bitcoin's security, he plans to sell all of his BTC holdings. His statement stems from an interview with IBM Chairman and CEO Arvind Krishna, who said that investors should be wary of the challenges quantum computing may pose to modern cryptography in the next 3 to 4 years. Cramer believes that quantum computing could threaten the Bitcoin network in a similar timeframe. However, no one has independently confirmed how much BTC he holds or whether he has completed the sale.After his statement, Bitcoin continued to trade normally around $63,764, with some market participants viewing his comments as a "reverse Cramer" signal. Bitcoin uses the ECDSA signature mechanism based on the secp256k1 curve, and theoretically, a sufficiently powerful quantum computer could use Shor's algorithm to derive the private key from the public key. The risk is mainly concentrated on addresses with exposed public keys, including reused addresses, early wallet formats, and the brief time window after a transaction is broadcast but not yet confirmed. Researchers estimate that about 6 to 7 million BTC, accounting for approximately 30% of the supply, may fall into this category. Google Quantum AI estimated in March this year that breaking the relevant cryptographic mechanisms could require fewer than 500,000 physical qubits, reducing the previous estimate by about 20 times. However, current quantum systems typically only have hundreds to thousands of physical qubits, with even fewer logical qubits that have higher reliability. Most researchers expect that truly capable quantum computers for cryptographic breaking may not appear until the 2030s or even 2040s, making Cramer's 3-year prediction significantly earlier than most technological expectations.

Trump said he would make a "final decision" on the Iran issue. American journalists interpreted that Trump hinted at approving the agreement

According to Jinshi reports, U.S. President Trump stated on social media: "Iran must agree that they will never have nuclear weapons or nuclear bombs. The Strait of Hormuz must be opened immediately in both directions, with no tolls, allowing shipping traffic to pass unrestricted. All mines (bombs)------if any------will be cleared (we have previously utilized our excellent underwater mine-sweeping ships to clear a large number of such mines by detonation. Iran will be responsible for immediately clearing and/or detonating any remaining mines------there shouldn't be too many!).Those ships that have been stranded in the strait due to our astonishing and unprecedented naval blockade------given that the blockade has now been lifted------can begin to "set sail for home"! The concentrated materials that are buried deep underground------sometimes referred to as "nuclear dust"------are currently being pressed under a mountain that has nearly collapsed (this is due to the powerful B-2 bomber airstrikes we launched 11 months ago); these materials will be excavated by the United States and will be thoroughly destroyed in close coordination and cooperation with Iran and the International Atomic Energy Agency. Until further notice, there will be no financial transactions between the two parties.In addition, the two sides have reached a consensus on other issues that are far less important than the above matters. I am now heading to the "situation room" for a meeting to make the final decision." AXIOS reporters interpret that Trump hinted at an imminent approval of the Iran agreement.

Analysis: Warnings of a dollar crisis are intensifying, gold and silver may surge in 2026, Bitcoin is said to be significantly undervalued

According to Forbes, as Bitcoin retreats from its historical high in October, concerns about the dollar system are rising. Analysts warn that the dollar may face structural downside risks, while the continued rise of gold and silver before 2026 could open up new upward space for Bitcoin prices.Data shows that Bitcoin is currently hovering around $90,000, a significant drop from its previous high of about $126,000; during the same period, gold has risen about 20% this year, and silver has surged by as much as 64%. Ramnivas Mundada, head of economic research at GlobalData, stated that the rise of precious metals in 2025 marks a shift in the international monetary system from a "dollar-centric" model to a multipolar structure, with expectations that gold still has an 8% to 15% upside potential by 2026, and silver may rise another 20% to 35%. Analysts believe that this trend is not merely a safe-haven trade, but rather a strategic allocation by institutional investors amid geopolitical tensions, a slowing U.S. economy, trade frictions, and accelerating "de-dollarization."The market is also betting on further interest rate cuts by the Federal Reserve in 2026, which would weaken the dollar's appeal. U.S. President Trump recently expressed hope that the new Federal Reserve chairman would actively cut rates when the market performs well, raising expectations for easing policies. Meanwhile, long-time dollar bear economist Peter Schiff bluntly stated, "Dollar hegemony is coming to an end," and claimed that gold will once again become a core reserve asset for central banks. Notably, while gold and silver have surged, Bitcoin's recent performance has lagged. Bitbank analyst Yu Nagatani also pointed out that against the backdrop of "overheating signs" in U.S. stocks and commodities, Bitcoin's current valuation appears low, which may attract valuation-based capital inflows in the future.
