The cryptocurrency market started the week with sharp sales.
The Bitcoin price fell below $100,000 for the first time since June 23, 2025, falling to as low as $98,944 during the day. This means BTC has lost over 7% of its value in the last 24 hours.
The decline was even deeper for Ethereum, with the price of ETH falling to $3,089, a daily drop of nearly 14%. This was one of the lowest levels for Ethereum in four months.
Analysts believe this decline is primarily due to the US Senate's renewed rejection of the interim budget bill. This federal government shutdown, which began on October 1st, has become the longest in US history, surpassing the 35-day record set in 2018–2019. Liquidity concerns and economic uncertainty have led investors to shift away from risky assets, intensifying selling pressure, particularly in the crypto market.
In addition, US stock indices, which Bitcoin is closely correlated with, also suffered deep losses today.
The average cost basis for spot Bitcoin ETFs traded in the U.S. is $89,613, according to K33 Research data. This figure is about 11% below the current price and represents a key technical support area.
“This asset class is inherently extremely volatile. Whether the current decline is a 'step back' or the start of a new downward wave remains to be seen,” said Bloomberg Intelligence analyst James Seyffart.
Bitcoin has historically rebounded from drops exceeding 50% numerous times. However, current macroeconomic pressures and deteriorating investor sentiment suggest the market is entering a challenging period.
