Jim Cramer Bitcoin sale plan cites quantum computing concerns
Jim Cramer said he plans to sell his Bitcoin after an IBM warning, while Bitcoin traded above $63,500 and the quantum timeline remained disputed.

Jim Cramer’s Bitcoin sale plan is based on concerns that quantum computing could eventually threaten cryptocurrencies, not on a reported completed transaction. The Mad Money host said he intended to sell his Bitcoin after a discussion with IBM Chairman and CEO Arvind Krishna, according to Cointelegraph. For investors, the immediate market backdrop was different: Bitcoin was trading above $63,500 on Tuesday, up about 1.7% that day.
“I’m going to sell mine,” Cramer said on a Friday episode of the CNBC program, according to Cointelegraph. The report did not disclose the size of his holdings or say that he had already sold them.
Cramer cited Krishna’s appearance on the prior day’s program. Cointelegraph reported that Krishna told Cramer to become “paranoid” about quantum computing’s potential threat to cryptocurrencies over the next three to four years.
Why is Jim Cramer selling Bitcoin?
Cramer’s stated reason was the possibility that advances in quantum computing could undermine cryptocurrency security. The concern is a long-term technology risk, and the evidence available does not establish that Bitcoin can currently be broken by quantum computers.
Google Research said in March that future cryptographically relevant quantum computers may be able to break elliptic-curve cryptography, which it said protects cryptocurrencies and other systems. Google said most blockchain technologies and cryptocurrencies rely on the 256-bit elliptic-curve discrete logarithm problem for important security functions.
The research group described post-quantum cryptography as a route toward stronger blockchain security, while cautioning that putting it in place would take time. It also recommended avoiding the exposure or reuse of vulnerable wallet addresses as a protective measure. Google’s work presents a future risk and mitigation path, rather than evidence of an existing Bitcoin breach.
When could quantum computing become a Bitcoin risk?
The timetable remains unsettled. Cointelegraph reported that Bernstein analysts said in an April report that Bitcoin had roughly three to five years to prepare for a post-quantum security upgrade. That is a preparation estimate, not a confirmed deadline for a quantum attack.
Other assessments are far less urgent. Blockstream CEO Adam Back said in November 2025 that Bitcoin faced no meaningful quantum threat for at least 20 to 40 years, according to Cointelegraph. Lacie Zhang, a research analyst at Bitget Wallet, told the publication that practical threats capable of breaking Bitcoin cryptography were highly unlikely within the next decade.
Bitcoin’s price move should also be kept separate from Cramer’s comments. Cointelegraph, citing TradingView data, reported the roughly 1.7% Tuesday gain and said Bitcoin was down 27% year to date. The report did not establish that Cramer’s planned sale caused the day’s price movement.
Some social-media users responded with the so-called “inverse Cramer” meme, treating his stated view as a contrary signal. Those posts are individual reactions, not evidence of a market effect or a basis for an investment decision.
Investing in Bitcoin carries risk, and neither Cramer’s stated plan nor competing forecasts about quantum computing determines whether buying or selling is warranted.
