Bitcoin has been making headlines in late 2025 for reasons that go far beyond just its price swings. Many people are asking if Bitcoin is being sold not just because of its own market moves but because investors are using it to cover margin calls in other parts of their portfolios. The answer is yes, and this is a growing trend that shows how deeply connected Bitcoin has become to the broader financial world.
When someone invests in stocks, bonds, or other assets, they often use borrowed money to increase their potential gains. This is called leverage. If the value of their investments drops, they may get a margin call, which means they have to put up more cash or sell some of their holdings to cover their losses. If they cannot do this, their broker will sell their assets automatically to make up the difference. This is what happened on a large scale in October 2025.
Bitcoin, unlike traditional assets, trades 24 hours a day and is highly liquid, meaning it can be sold quickly for cash. When global markets became unstable due to rising tensions between the United States and China, rate cuts by central banks, and regulatory uncertainty, many investors faced margin calls across their portfolios. Because Bitcoin could be sold at any time, it became one of the first assets to be liquidated to raise cash and meet these margin requirements.
This was not just a small event. Over a 24-hour period in mid-October, more than $19 billion worth of leveraged positions in Bitcoin were forcibly closed. This massive wave of selling was not only driven by Bitcoin’s own price drop but also by the need for investors to cover losses in other markets. As Bitcoin’s price fell, it triggered more margin calls on leveraged Bitcoin positions themselves, creating a feedback loop where falling prices led to more forced selling, which pushed prices even lower.
The situation was made worse by the high levels of leverage in the crypto market. Many traders use leverage ratios of 20x, 50x, or even 100x, meaning a small drop in price can wipe out their entire position. When the price of Bitcoin dropped by just a few percent, it was enough to trigger liquidations for thousands of traders. These forced sales added even more downward pressure on the price, which in turn led to more margin calls and more selling.
This pattern is not unique to Bitcoin, but Bitcoin’s structure makes it especially vulnerable. Traditional markets have circuit breakers and trading halts to prevent panic selling, but crypto markets do not. This means that when a crisis hits, Bitcoin can be sold off rapidly, sometimes in minutes, to cover margin calls in other assets or to meet obligations within the crypto market itself.
Another factor is the growing correlation between Bitcoin and other risk assets, especially US tech stocks. In late 2025, the correlation between Bitcoin and the Nasdaq 100 index reached its highest level in nearly three years. This means that when tech stocks fall, Bitcoin tends to fall too, and vice versa. As a result, when investors are forced to sell tech stocks to cover margin calls, they are also likely to sell Bitcoin at the same time, further amplifying the effect.
The rise of automated trading platforms and copy trading bots has also played a role. When markets move quickly, these systems can trigger mass sell orders based on pre-set rules, such as stop-losses or leverage limits. In October 2025, many of these bots executed sell orders as soon as certain price levels were hit, adding to the wave of liquidations. Traders who used adaptive stop-losses and dynamic risk controls were able to preserve more of their capital, but those with static strategies saw much larger losses.
The stress on market infrastructure was also evident. Major exchanges and trading platforms faced unprecedented levels of margin calls and risk management challenges. Some platforms struggled to keep up with the volume of liquidations, leading to delays and even temporary outages. This further eroded confidence and led to more panic selling.
The events of October 2025 have also sparked calls for stricter regulation of leverage in the crypto market. Regulators are likely to impose tighter limits on how much leverage retail traders can use, bringing it more in line with traditional financial markets. There will also be greater scrutiny of exchange risk engines and liquidation mechanisms to prevent the kind of cascading failures that occurred during the crash.
Bitcoin’s role as a liquidity gauge is now more apparent than ever. When global markets are under stress, Bitcoin is often one of the first assets to be sold to cover margin calls in other assets. This is not just a sign of weakness but a reflection of Bitcoin’s growing importance in the global financial system. As more institutions and investors use Bitcoin as part of their portfolios, its price will continue to be influenced by events far beyond the crypto world.
The high levels of open interest in Bitcoin futures and the record amount of cash collateral backing these contracts show that the market is highly leveraged and sensitive to changes in liquidity. When macroeconomic risks rise, such as trade tensions or shifts in monetary policy, the impact on Bitcoin can be swift and severe. This is why changes in global M2 money supply and broader trends in monetary expansion continue to play a major role in Bitcoin’s price cycles.
For investors, the lesson is clear. Leverage can amplify gains, but it also magnifies losses, especially in times of high volatility. Those who use leverage in their portfolios, whether in crypto or traditional assets, need to be prepared for the possibility of margin calls and forced liquidations. The events of October 2025 have shown that Bitcoin is not immune to these risks and can be sold off rapidly to cover obligations in other parts of the financial system.
The growing use of multi-asset portfolios, including stablecoins and gold-backed tokens, is one way investors are trying to hedge against these risks. By diversifying their holdings and using dynamic risk controls, they can better protect themselves from the kind of cascading liquidations that occurred in October. However, as long as leverage remains high and markets are interconnected, the risk of forced selling will continue to be a feature of the crypto landscape.
Bitcoin’s price action in late 2025 has also highlighted the importance of real-time monitoring and adaptive strategies. Traders who were able to adjust their positions quickly and reduce their leverage during the crash were able to preserve more of their capital. Those who relied on static strategies or ignored the warning signs saw much larger losses. The ability to respond to changing market conditions is now more important than ever.
The events of October 2025 have also shown that Bitcoin is increasingly behaving like a highly leveraged technology stock. Its price is closely tied to broader market sentiment and macroeconomic factors, and it can be sold off rapidly when global markets are under stress. This means that investors need to pay close attention to developments in the wider financial world, not just what is happening in the crypto market.
The high levels of long-term holder sales in October 2025, signaling profit-taking and reduced confidence in Bitcoin’s near-term trajectory, further underscore the impact of external factors on the market. When investors lose confidence in the broader economy, they are more likely to sell their Bitcoin holdings to cover margin calls or to move into safer assets.
The collapse of a major stablecoin and the resulting de-pegging event also played
