Former hedge fund manager and CNBC “Mad Money” host Jim Cramer said he plans to sell all his Bitcoin due to quantum computing fears. “I’m going to sell mine [Bitcoin],” said Cramer during a Friday episode, citing quantum computing concerns that IBM chairman and CEO Arvind Krishna had raised on his show the previous day. During Thursday’s episode, Krishna told Cramer that he should get “paranoid” about quantum computing’s threat to cryptocurrencies in the next three to four years.Bitcoin’s (BTC) price was up 1.7% on Tuesday to trade above $63,500, but was down 27% year-to-date, according to TradingView data. Some crypto investors celebrated Cramer’s remarks, referencing the popular “inverse Cramer” meme and investment philosophy, which ironically seeks to capitalize on the opposite of the investment calls made by the former fund manager.“If Cramer is selling, it’s time to start buying,” commented GRIT Trading Academy founder Archie Spencer. “Every time Cramer says sell, I add to my position.

In November 2025, Blockstream CEO Adam Back said that Bitcoin faces no meaningful quantum threat for at least the next 20 to 40 years. In contrast, analysts at Bernstein said that Bitcoin has about three to five years to prepare for a post-quantum security upgrade, in an April report. “Back’s assessment is the more accurate and measured view: practical quantum threats capable of breaking Bitcoin’s cryptography remain highly unlikely within the next decade,” Lacie Zhang, research analyst at Bitget Wallet, told Cointelegraph.Magazine: Bitcoin’s quantum upgrade path: What BIP-360 changes and what it does not
