2. Stronger U.S. dollar:The U.S. Dollar Index (DXY) has risen, which tends to put downward pressure on Bitcoin prices as a stronger dollar reduces the appeal of riskier assets like cryptocurrencies.

3. Higher bond yields: Rising U.S. Treasury yields also increase the opportunity cost of holding non-yielding assets like Bitcoin, further contributing to the decline.

4. Geopolitical and regulatory concerns: Legal actions, such as the prosecution of the founders of Samourai Wallet, have heightened regulatory concerns, impacting market sentiment.

These factors combined have led to a decrease in Bitcoin's price today.
