The world's largest cryptocurrency dropped approximately 6.3 per cent to $69,101.10, according to market data reported by Investing.com on Friday. The decline brought bitcoin to a near three-month low and extended a period of weakness that has affected digital assets since October.

A key factor behind the sell-off is the changing outlook for US interest rates. Higher-than-expected consumer inflation data for October have strengthened expectations that the Federal Reserve could raise borrowing costs as early as December.

Market pricing indicated expectations of between 25 and 50 basis points of potential tightening, according to CME FedWatch data cited in the market report.

The prospect of higher interest rates can weigh on cryptocurrencies because investors may become less willing to hold volatile assets when returns on conventional financial instruments become more attractive. Tighter financial conditions can also reduce liquidity available for speculative investment.

Institutional developments have added to the pressure. MSCI has ruled that Strategy, one of the largest corporate holders of bitcoin, will be removed from its global benchmarks at the end of November. The decision has raised questions about potential changes in institutional exposure to companies whose business models are heavily linked to cryptocurrency holdings.

Strategy's position in the market has made it an important reference point for investors assessing the relationship between publicly listed companies and digital assets. Its removal from MSCI indexes could influence investment flows from funds tracking those benchmarks, although the actual effect will depend on individual fund decisions.

Bitcoin's decline also reflects the broader weakness affecting technology shares and other risk-sensitive assets. Investors are reassessing the outlook for monetary policy, corporate valuations and the durability of recent market gains.

The latest price movement does not, on its own, establish a long-term change in bitcoin's market structure. Cryptocurrency prices remain sensitive to liquidity conditions, regulatory developments, investor positioning and expectations surrounding institutional adoption.

For market participants, the immediate focus will be whether bitcoin can regain the $70,000 level or whether further selling pushes prices towards lower support areas.

The Federal Reserve's December policy decision, subsequent inflation readings and changes in institutional cryptocurrency exposure will be important indicators of the market's direction.
