Bitcoin Falls as Security Fears Pressure Crypto Market

Bitcoin traded around $82,800 on Saturday as the largest cryptocurrency faced a nearly 3% weekly decline. The drop came amid rising oil prices, higher U.S. interest rates and renewed security concerns that pressured investor sentiment across crypto markets.

According to Investing.com, Bitcoin was trading at $82,790.9 by 07:18 ET, after moving between $82,537.7 and $82,941.6. The cryptocurrency had briefly approached $87,000 the previous Sunday before losing ground during the week.

Rising energy prices and higher Treasury yields have pressured cryptocurrency markets, according to Investing.com. The report said concerns about artificial intelligence affecting hardware wallet security, a Ledger-related theft report and the anniversary of last year's October 10 flash crash added uncertainty.

A CoinDesk analysis found Bitcoin recorded 10 days in 2026 when its price moved at least three standard deviations from its recent trading pattern. The figure exceeded the eight such days recorded throughout 2018.

CoinDesk's analysis also showed annualized volatility declined to about 46% in 2026 from 84% in 2018. Average three-standard-deviation moves narrowed to roughly 7% from 10%, while unusually large price swings remained frequent.

Investors are awaiting September consumer price index and producer price index reports scheduled for next week. The data will provide further indications about whether the Federal Reserve could resume raising interest rates.

Markets currently expect the Federal Reserve to keep its benchmark rate unchanged at the October 27-28 meeting, according to the report. A possible 25-basis-point increase is expected in December, while higher rates can reduce demand for speculative assets such as Bitcoin.

Security concerns also affected sentiment after Ledger launched an investigation into reports of missing cryptocurrency linked to devices sold through a Southeast Asian reseller. Ledger has not confirmed the estimated losses or determined the cause.

Blockchain investigators estimated potential losses between $86 million and $93.4 million, according to the report. Ledger asked reseller CryptoBilis to suspend sales and shipments during the investigation, with no confirmed evidence that Ledger's own systems were compromised.
