Billionaire investor Mark Cuban has sold most of his Bitcoin holdings, saying the cryptocurrency has 'lost the plot' and failed as both an inflation hedge and a geopolitical safe haven. His comments drew an immediate rebuttal from Blockstream CEO Adam Back, who pointed to recent price data that he says tells a different story.
Cuban's case against Bitcoin
Cuban's frustration stems from a period when Bitcoin fell more than 40% while gold surged to $5,000. He argued that the digital asset didn't protect his portfolio during a time of geopolitical stress and rising inflation. Cuban made clear he remains more optimistic about Ethereum going forward, suggesting a shift in his crypto allocation.
Back's data-driven response
Adam Back wasn't buying it. He cited data showing that since Middle East tensions escalated, Bitcoin rose 25–30% from a low of roughly $60,000. Over the same stretch, the S&P 500 gained 11%, the Dow Jones rose 5%, and gold actually fell 14%. Back suggested Cuban may have sold at the bottom — noting that his critique doesn't align with the recent numbers.
That's a sharp contrast. Cuban's disappointment is rooted in an earlier crash, but Back argues the context matters. He attributed the earlier Bitcoin drop to what he called a '10/10 event' and normal halving-period cyclicality, not gold's geopolitical gains.
The long-term picture
Some long-term model followers argue Cuban's take reflects a fundamental misunderstanding of Bitcoin's price cycles. Back himself stressed that Bitcoin's volatility is necessary for its outlier Sharpe ratio over longer durations. He pointed out that Bitcoin's risk-adjusted returns over multiple years have consistently beaten equities, gold, and real estate.
Whether Cuban sold near the bottom or made a strategic exit remains an open question. But the debate lays bare the persistent divide between Bitcoin's true believers and those who've turned skeptical after a rough stretch.
