Bitcoin briefly climbed to roughly $115,000 on Friday, its highest level in months, after Federal Reserve Chair Jerome Powell opened the annual Jackson Hole Economic Policy Symposium with remarks interpreted by markets as dovish. Traders pushed the world’s largest cryptocurrency higher within minutes of Powell’s appearance, betting that softer policy rhetoric could translate into a looser liquidity backdrop. The move extended a week-long advance for digital assets and outpaced gains in other risk assets during the session.
