Bitcoin surged back above $70,000 this week for the first time in more than two months, climbing past $71,500 after a rapid string of catalysts hit the crypto market at once. The move builds on a 7% rally the day before that erased $2.7 billion in short positions, and it comes alongside gains across other digital assets, including a 23% jump in a token tied to the offshore derivatives exchange Hyperliquid.
