Quantum Computing Can Break Bitcoin. Are Fears Driving the BTC Price Down?
Bitcoin is down as the Iran conflict grows worse and fears over quantum computing security risks still looms large.
In early 2026, a Google whitepaper revealed that quantum computing could break Bitcoin’s security algorithms, and analysts are still talking about the dangers as the first hack seems inevitable and close.

Bitcoin (BTC) fell 2.11% on Tuesday morning, following a drop across the stock market that caused the Nasdaq and S&P 500 to lose their fresh highs. Several major companies reported earnings that were less than spectacular, resulting in mostly declining stock values for the day. However, Bitcoin’s struggle to hit $80K this week could be caused partially by fears over quantum computing.
BTC/USDWe reported recently that quantum computers could break Bitcoin security and allow hackers to steal coins from investors’ digital wallets. It is no wonder that this serious security risk has sparked a number of worried articles from industry experts, and it may be one factor holding the BTC rate back from passing $80,000.
Bitcoin Falls on Poor Market Sentiment
If Bitcoin does not have investor support behind it, the coin slips from its level and loses ground. On Tuesday, Bitcoin fell to $76,065 (BTC/USD), and it is now even further from hitting the psychologically important $80K level. The token has not been able to pass that mark since early February when stocks and crypto tokens all dropped as the Iran conflict began.
That ongoing fighting between Iran and the United States has kept the crypto market subdued, creating a hindrance for tokens to regain lost ground. Bitcoin managed to move upward slowly in recent weeks, but this week it stumbled hard. It is still up for the month, having gained more than 14% over the last 30 days, but several factors are working against Bitcoin and its ability to hold onto those gains.
That Google whitepaper is damning for Bitcoin’s security, exposing flaws that will become even more egregious as quantum computing advances. This problem does not put all bitcoins at risk, but it does make many wallets vulnerable, and it could just be a matter of time before all Bitcoin accounts are exposed and easily hackable. Security is one of the strengths of cryptocurrency, but if that changes, then investors may be wise to abandon the coin.
Biton is also being hurt by ongoing fighting in Iran. The situation there became much worse this week after both Iran and the United States lodged complaints that their ceasefire had been broken by the other side. The potential for peaceful negotiations is still there, but neither side seems willing to make the concessions that their opponents are asking for. Peace is in the best interest of the global economy since the important Strait of Hormuz in the region is used for transporting much of the world’s oil, but until the situation is resolved, the risk of a global energy crisis is high.
Bitcoin is going to struggle to hit new milestones while these factors are weighing so strongly on investors’ minds. The coin could push past $80K quickly without the pressure that security risks and the Iran conflict bring to it. For now, we anticipate Bitcoin will continue to work its way slowly upward, with continued setbacks like what occurred Tuesday morning.
