Mark Cuban sells 80% of BTC after crisis failsafe test

Reason for the sale: Safe haven debate

Cuban expressed his disappointment over Bitcoin’s inability to function as a reliable refuge in times of global crisis. While traditional assets such as precious metals surged in value amidst recent geopolitical upheavals, Bitcoin’s brief downturn during this period prompted Cuban to offload most of his holdings. He considers this divergence a negative signal for the leading cryptocurrency.

Bitcoin did not offer the protection I expected during recent events—I think it has lost its meaning, Mark Cuban said, reflecting on his rationale for selling.

Criticism from industry analysts

Longtime crypto industry veterans were quick to argue that Cuban’s judgement is based on short-term market moves. Analysts point out that Bitcoin operates in four-year cycles and that snap price fluctuations should not be used as grounds for drawing long-term conclusions about its viability as an asset.

Adam Back, CEO of Blockstream and a respected voice in the crypto space, shared his thoughts on Cuban’s actions via X. According to Back, current market data does not support Cuban’s thesis.

The numbers don’t match Mark Cuban’s claims; the only way they would is if he somehow sold at the very bottom, Adam Back stated.

Bitcoin’s performance vs traditional markets

Following a short period of volatility, Bitcoin rebounded sharply from around $60,000, recording a 25–30% rally. Over the same time, the S&P 500 climbed 11% while the Dow Jones rose by 5%. Interestingly, gold—a traditional safe haven—dropped by 14%, calling into question its status as a defensive asset.

Market commentators noted that, despite his liquidation, Cuban may have misread the broader trend, as many cryptocurrencies saw rapid recoveries during the same phase.

Mark Cuban’s crypto journey

Mark Cuban’s investments span the tech and sports worlds, including his high-profile stint as the owner of the Dallas Mavericks basketball team. Initially, he took a skeptical stance toward cryptocurrencies and questioned Bitcoin’s real-world utility.

In 2019, he famously quipped that he considered Bitcoin less valuable than a banana. Yet in the years that followed, Cuban developed an interest in decentralized finance (DeFi) applications and became a public supporter of one of the most recognized meme-coins, Dogecoin.

Mini Glossary: DeFi (Decentralized Finance) refers to a financial ecosystem where users carry out traditional banking functions through smart contracts and blockchain networks, without the need for intermediaries.

Over time, Cuban shifted his perspective and explored the ecosystem further, but in recent months, he resumed a critical tone—labeling both Bitcoin and speculative coins as “garbage.”

Cuban’s reversals have made him a lightning rod for debate in both crypto and mainstream financial circles, as he often expresses his evolving views on the emerging digital asset landscape.
