Television personality and former hedge fund manager Jim Cramer says he plans to sell all of his Bitcoin, citing concerns that advances in quantum computing could eventually threaten the cryptocurrency’s security.
The comments, made during CNBC’s Mad Money, sparked debate across the crypto industry, with some investors dismissing the warning as premature while others pointed to the ongoing discussion around Bitcoin’s long-term cryptographic resilience.
At the time of writing, Bitcoin traded above $63,500, gaining roughly 1.7% on the day but remaining about 27% lower year-to-date, according to TradingView.
Cramer Cites Quantum Computing Risk
Cramer’s decision followed remarks from IBM Chairman and CEO Arvind Krishna, who appeared on the program a day earlier.
Krishna advised investors to take the potential impact of quantum computing seriously, suggesting the technology could pose challenges to cryptocurrencies within the next three to four years.
That outlook prompted Cramer to announce he intends to exit his Bitcoin position.
However, the comments quickly reignited the popular “Inverse Cramer” narrative on social media, where many crypto traders jokingly interpret Cramer’s bearish calls as bullish market signals. Several investors publicly said they were increasing their Bitcoin exposure following his remarks.

Whales Move Bitcoin as Market Liquidity Falls
Cramer’s comments come as on-chain activity points to shifting market dynamics.
Blockchain analytics platform Lookonchain reported that a long-dormant whale wallet transferred its entire 16,400 BTC, valued at roughly $1 billion, to a new address after seven months of inactivity.
At the same time, crypto market liquidity has weakened. Data shared by The Kobeissi Letter, citing Kaiko, showed daily spot trading volume across the largest 44 cryptocurrency exchanges dropped to $15 billion last week—the lowest level recorded in 2026 and approximately 70% below January’s peak.
Lower trading activity often signals reduced market participation and can contribute to greater price volatility.
Experts Disagree on Quantum Computing Timeline
While quantum computing remains a widely discussed topic, industry experts are divided over how soon it could realistically threaten Bitcoin.
Blockstream CEO Adam Back has argued that practical quantum attacks remain decades away, estimating a timeline of 20 to 40 years before the technology becomes a meaningful risk.
Other analysts, including researchers at Bernstein, believe Bitcoin developers should prepare for post-quantum security upgrades within the next three to five years.
Meanwhile, analysts at Bitget Wallet and Bitfinex described immediate concerns as overstated, noting that no existing quantum computer is currently capable of breaking Bitcoin’s cryptography at scale. They also emphasized that any future quantum breakthrough would impact traditional banking systems, government infrastructure, and other technologies that rely on modern encryption—not just cryptocurrencies.
